The WAGO I/O System

The WAGO I/O SYSTEM consists of various components which are capable of

providing modular and application specific fieldbus nodes for various fieldbusses.

I11.1 Setting up a fieldbus node with the WAGO I/O SYSTEM

General remark:

A fieldbus node consists in principle of a fieldbus coupler at the front end, a number of

special function modules and a termination module which is placed at the other end.

1 - Buscoupler

The Buscoupler forms the link between the fieldbus and the field devices with their I/O

functions. All control functions required for the faultless operation of the I/O functions

are carried out by the coupler. The connection to different fieldbus systems is

established by each of the corresponding Buscouplers, e.g. for PROFIBUS, INTERBUS

S, II/O LIGHTBUS, CAN, ModBus etc. In this way a change of the fieldbus system is

possible.

2 - Function modules

In the function modules, the incoming process data ais converted. Corresponding to the

different requirements, special function modules are available for a variety of functions.

There are digital and analog inputs and outputs and modules for special functions. The

modules are described in the following chapters.

3 - Termination module

A termination module is needed for faultless operation of the node. The termination

module is always placed as the last module in order to obtain a termination of the

fieldbus node. This module has no I/O function.

Assembly of the WAGO I/O System

All components of the system can be snapped directly on a carrier rail according to EN

50022 (DIN 35).

When snapping the analog or digital components onto the rail, no special sequence must

be observed. The secure positioning and connection of the individual function modules

and the coupler is provided by a snap-in system. This snap-in system provides automatic

interlocking onto the DIN rail assembly. It is always possible to remove a function

module or the Buscoupler from the assembly by pulling the orange pull-tab.

Please note, that the power supply of the field side as well as the data transmission are

interrupted. It has to be ensured that the interruption of PE will not put personnel or

equipment in danger.

With a CAGE CLAMP, conductors with a cross section of 0.08 to 2.5mm²/AWG 18-14

can be connected. Vibration proof, fast and maintenance-free. You simply introduce a

screwdriver or an operating tool into the operating slot under the clamping unit. The

CAGE CLAMP spring is pressed down. You can now introduce the wire into the

clamping unit. Withdraw the operating tool and the conductor is automatically clamped.

Interbus / Introduction

Download from Www.Somanuals.com. All Manuals Search And Download.

The clamping force adjusts automatically to the conductor cross section. The flat

clamping face of the CAGE CLAMP spring presses the conductor against the current

bar without damage. Any deformation or movement of the conductor is compensated,

thus eliminating the risk of a loose connection. The contact point between conductor

and CAGE CLAMP is well protected against corrosive deterioration. This connection is

made fast and, furthermore, it is maintenance-free. There is no need for costly periodical

examination of the connections.

The supply modules of the WAGO I/O system are partly equipped with a fuse holder.

This fuse holder can be pulled out in order to break the circuit of the following modules.

To do so, you first have to insert a screwdriver into one of the slots on both sides in

order to pull out the front side of the fuse holder.

The front side now being hinged down makes it possible to remove or to insert the fuse.

After that, you lift up the front side again and push the fuse holder back into its original

position.

Buscoupler - INTERBUS S

2.1 Buscoupler - Hardware

Ill. 2: The INTERBUS buscoupler

The 750-304 Interbus coupler consists of two major electronic sub systems:

left side:

This housing contains the electronics for the coupling to the bus, the processor

and the fieldbus connection. (ill. 2.1)

right side:

This housing contains the DC to DC converter and power distribution for the internal K

bus, local processor and external 24 V DC connections to other discrete I/O modules.

Illustration 2.2 identifies the 24 V DC connection points to supply voltage to I/O

modules. Illustration 2.3 identifies the ground connection.

2.2 Supply Voltage - Electronics

Ill. 3: Termination points for the power supply and the internal electronics

The nominal operating voltage of the Buscoupler and the control electronics in the

function modules is 5 V DC. The supply is connected to the first two CAGE CLAMPS

at the top of the coupler as seen in Ill. 3.

The 24 V DC supply voltage is generated by an internal voltage regulator (DC/DC

converter) and fed to the electronics (5 V DC). The electrical isolation of the external

bus system is made by utilizing an optocoupler.

Please note that the power supply for the control electronics in the function modules is

made automatically by the data contacts of the following module when it is snapped on

the assembly (ill. 3.1). The power supply to the attached I/O modules is provided by

gold-plated self-cleaning slide contacts. If an attached module is taken out of the

existing configuration, the connection via the K bus is broken and the coupler is able to

detect this.

WARNING

If a module is taken out of the existing configuration, there may be undefined states.

You should disconnect the power supply when changing anything in the configuration.

2.3 Supply Voltage - Field Side

Ill. 4: Termination points for the supply voltage - Field side

The connection of the supply voltage is electrically isolated from the internal

electronics. Two CAGE CLAMPS are always connected by a power contact. By this

way, the power supply is taken to different points of the configuration.

It is possible to supply the following at the termination points (Ill. 4):

Volts: 24 V DC - Amps: 10 A DC

WARNING!

120 and 230 V AC can only be supplied via modules 750-609, 750-611 and 750-612!

The supply modules which are permanently integrated on the buscouplers, can be

supplied with 24 V DC only. The current on the power contacts should be max. 10 A.

The voltage is automatically supplied when the function modules are snapped together.

Self-cleaning power jumper contacts (P.J.C.s) ensure safe connections (Ill. 4). Female

contacts (current supply) are integrated in the buscoupler and I/O housings. The male

contacts on the buscoupler and I/O housings supply the voltage to the I/O modules when

inserted together from left to right.

The ground (earth) contact makes first and breaks last conforming to electrical standards

and can be used as protective grounding.

Depending on the I/O function, some modules do not have P.J.C.s. It is important to

note this when assembling a node. Many modules require field side power, many do

not. Please review the circuit diagrams of the individual modules. An additional power

supply module may be necessary.

When using the supply module 750-601/602, the field supply from the bus coupler is

interrupted. From that point a new power supply connection is necessary to provide DC

to any additional I/O modules.

WARNING!

The ground ( earth) field side contact should be disconnected when testing the isolation.

Otherwise the results could be wrong or even the module could be destroyed.

Interbus S buscoupler with extended diagnostics 750-304/000-001

The Interbus S buscoupler with no. 750-304/000-001 has the possibility of extented

diagnostic functions. The technical data is the same as 750-304.

Different from the standard buscoupler, a word for diagnostic messages is put into the

input data process image and a word for the control of the diagnostic input is put into

the output data process image.

The maximum number of input and output modules is reduced by the additional

diagnostic function because Interbus S transmits only 31 words of a process image.

INTERBUS S

The Interbus S system (DIN 19245 part 1.2) is set up as a data ring with a central master

slave access procedure. All modules are understood as one logical module. Each partner

receives data at its input and sends it to the next partner at its output. There is no

addressing with a data frame because each partner knows by special control signals

(CLOCK, RESET, SELECT, CONTROL) where it is placed in the ring. So there is no

bus address. „Addressing“ is done via the physical place in the system.

Interbus S has the structure of a spatially distributed shift register. Each cycle is input

and output at the same time. While the master gives output data to the shift register, it

gets input data from the other end of the ring.

Each part of Interbus S has an ID register. This register keeps information about the type

of module, the number of I/O registers and the status and error information.

Interbus S has two general operating modes:

1) ID cycle

The interface module of all devices connected to the bus system reads out the ID register

in the ID cycle and builds up the process image with the aid of this information. The

cycle serves as an initialization and is carried out on request.

2) Data cycle

Within the data cycle all input data from the registers is transferred from all devices into

the master card (Host Controller) and all output data from the master card (Host

controller) to the devices.

4.1 Master Cards (Scanners, Host Controllers)

The operation of the master is carried out in most cases via a central controller like a

PLC, PC or NC. Connection to the remote stations is made via master cards.

Common master modules are:

- Phoenix IBS S5 DCB/I-T

- Phoenix IBS S5 DSC/I-T

- Phoenix 100 CB-T

- Hilscher CIF 30 (via Synergetic Micro Systems in USA)

4.2 Configuration software

In order to make the connection between a PLC or PC and the remote stations, the

master cards must be configured with the individual station data.

For this, the following software packages are available. For example, the following are

available from Phoenix:

5.1 Identification Code

In the ID cycle which is carried out for the initialization of the Interbus system, the users

connected users are identified by their function and their byte length. The Interbus S

coupler identifies its length after being started in the initialization phase of the bus

modules and forms a corresponding ID code. To this effect each slave has an

implemented identification register (ID register) comprising 2 bytes.

A 2 byte wide data unit is called a word. It enables the encoding of 65536 different

states. In Interbus S, different types of users and data widths are called for the coding.

This enables the master to find out what type the device belongs to, which means for

example, recognizing either frequency inverters or I/O units, like the

:$*2Ç,ꢁ2Ç6<67(0ꢂ In Interbus S the manufacturers of device types are not

recognized. The structure of the ID code is explained below as well as the significance

of the individual bits of the ID code.

The length information can be coded from 0 to 32 words:

messages

data width

class of user

type of user

data direction I, O, I/O

Table 2: Structure of the Interbus ID code

-In the ID registers, the device group is coded in the lowest value (LSB) 8 bits (ID 0 to

7).

-In the following 5 bits (ID 8 to 12), the data width is coded. The 3 bits with the highest

value (MSB) (ID 13 to 15) are used for management functions. Via these bits, dynamic

fault messages are transferred during operation. These bits are not defined by the

hardware.

5.2 ID Code for WAGO I/O System

Due to the combined use of digital, analog and special functions on one fieldbus station

and with the given structure of the Interbus ID codes, it is impossible to manage with

one ID code.

The WAGO Interbus S buscoupler is identified as a digital slave with variable length!

Table 3: ID codes for the WAGO Interbus S buscoupler

For the master, it is important to know how many data registers each user assigns in the

Interbus S system. If a user has, for example, 16 bits of input and 32 bits of output, he

assigns 2 words in the bus because there are 2 words of output. In this case the higher

value of data width is decisive. The data width is coded by the bits ID 8 to ID 12 as

shown in section 5.1.

The following table shows the register widths depending on the function modules

Buscoupler startup and troubleshooting

After configuration of the master connection and electrical installation of the fieldbus

node/station, operation of the system can begin.

After power to the Buscoupler and I/O modules has been applied, the Buscoupler

verifies all internal functions, components and the communication interface by an

internal diagnostic routine. Then the function modules and the existing configuration is

determined. At the same time a hidden file is stored. It consists of an input and an output

area which is located on the fieldbus RAM of the log chip. During the power up phase

the ‘I/O ERR’ LED flashes with an increased frequency. After a faultless power up the

fieldbus coupler enters the state ‘fieldbus start’. The green LED ‘RUN’ indicates that

the Bus is operating normally.

In case of a fault the red ‘I/O ERR’ LED will continue flashing.

By counting the number and frequency of flashes the fault can be easily identified

quickly and accurately. A varying number of flashes and frequencies defines the fault.

The table below describes the fault condition based on the counted number of ‘I/O ERR’

LED flashes.

After elimination of the fault, the buscoupler can only be set to the normal working

condition by another POWER ON sequence.

The green I/O LED flashes when accessing the I/O modules internal data channels.

After being switched on, the buscoupler queries the configuration of the bus modules

but does not carry out a data exchange with the I/O modules. This means that the red I/O

LED will extinguish after a faultless startup. The green I/O LED will indicate when data

is being exchanged by the Interbus network.

Digital Inputs (24 V AC/DC, 120 V AC, 230 V AC, 48 V DC)

PN: 750-400...415

Technical description

The supply is applied by a series-connected termination to each I/O module for the

respective operating voltage. Power connections are made automatically from module to

module when snapped onto the DIN rail.

Attention:

The lowest power jumper contact is not carried out for some modules (e.g. 4-channel)!

A module which needs all contacts (e.g. 2 channel digital) may not be connected to the

right hand side of modules which do not have 3 power jumper contacts (e.g. 4 channel

modules).

All 2-channel digital inputs are 4-conductor devices allowing the direct connection of 4-

conductor sensors with the terminations V+, 0V, ground and signal.

The 4-channel digital inputs are suitable for the direct connection of two 3-conductor

sensors (V+, 0V, signal). The power distribution module 750-614 is available for the

connection of more sensors to V+ and 0V.

The modules 750-408 and 750-409 are low-side switching.

A 2-wire proximity switch can be connected to the modules 750-410 and 750-411.

RC filters are series-connected to the 5, 24 and 48 V versions for noise rejection and

switch debouncing. They are available with time constants of 3.0 ms and 0.2 ms.

The standard numerical assignment for bus operations is from left to right, starting with

the LSB. The positions of the different I/O modules in the configured node/station are

selectable by the user. A block type configuration is not necessary.

The Input module can be connected to all buscouplers of the WAGOÇI/OÇSYSTEM.

Organization of the in- and output data:

The counter begins processing with pulses at the CLOCK input. The changes from 0 V

to 24 V are counted.

The counter counts up, if the input U/D is set at 24 V. With an open circuit input or 0 V

the counter counts backwards.

The two bottom contacts each include another output. These outputs are activated

through bits in the control byte.

The control byte has the following bits:

With the control and status-byte the following tasks are possible:

Set the counter: Put Bit 5 into the control byte. The counter with the 32 bit value is

loaded into output bytes 0-3. As long as the bits are set, the counter can stop and

information is stored. The ensuing data of the counter will be conveyed to the status

byte.

Blocking the counter: Bit 4 is set into the control byte, then the count process is

suppressed. Bit 4 in the status byte communicates the suppression of the counter.

Set the outputs: Bits 2 and 3 set the additional two outputs of the counter module.

The result of the counter is in binary.

Technical Description

The counter module 750-404/000-003 measures the period of the 24 V DC input signal

at the CLOCK terminal and converts it into a corresponding frequency value. The

measurement is enabled if the GATE terminal is an open circuit input or 0V. To disable

processing, the GATE input is to be set to 24 V DC.

The terminals O1 and O2 work as binary outputs. Each output can be activated via

Functional description

The counter module acquires the time between one or more rising edges of the CLOCK

input signal and calculates the frequency of the applied signal.

The calculation and process image update are initiated every 1^st, every 4^thor every 16^th

rising edge depending on the integration time selected via the CONTROL byte. The first

detection of a rising edge starts the cyclic period measurement and cannot provide a

valid frequency value. In this case the module will send 0xFFFFFFFF_Hfor input

information. The same input value is returned when a static high or static low signal is

applied to the CLOCK input.

If there are no signal changes seen at the CLOCK input, the module can be forced to

update the process image after defined parameterizable time spans. In this state the

module will send the non valid value 0xFFFFFFFF_Htoo.

The following figures illustrate a process data cycle.

Structure of Input and Output data

The input data contain the CLOCK frequency as a binary value. The representation

depends on the RANGE_SEL bits in the CONTROL byte. Even the method of

measuring is selected via these bits. The following table illustrates the different modes.

)UHTXHQF\ꢀLQꢀ+]

Attention:

When a new frequency range is requested, the application has to wait for valid data until

the RANGE_SEL ACK bits contain the new frequency range. The maximum delay can

be calculated using the following formula

number of periods to be integrated

T_Dmax= 2 *

actual frequency

If the gate is enabled the input data contains the last valid frequency value. In this state

the application cannot request a new range.

The valid frequency range stretches from 0.1 Hz (100_D) up to

10 kHz (100000_D).

To recognize static CLOCK signals, a watchdog timer is implemented. The default

value for the timer is 10s. The timer resets on every Power On.

The application is able to change the watchdog time during operation by using the

CONTROL byte.

This can be initiated by writing the corresponding value into the output bytes

OUTPUT_DATA 1 and OUTPUT_DATA 0 before setting the T_VDREQ bit in the

CONTROL byte.

The success of the parameter transfer is acknowledged by the module via the T_VDACK

bit in the STATUS information.

Attention:

The range of the watchdog timer stretches from 0 to 16383ms (0x0000_Hto 0x3FFF_H) in

steps of 1ms per digit.

Values which raise the permitted range of the watchdog timer are masked with 0x3FFF.

If the maximum possible frequency of the different ranges is raised (see the table with

maximum frequency ratings), the module will return the non valid data 0xFFFFFFFF_H.

Digital Outputs (Standard)

PN 750-501...504, 516, 519

Technical description:

The power supply is provided by a series-connected supply module for the respective

operating voltage. Power connections are made automatically from module to module

via the internal P.J.C.s when snapped onto the DIN rail.

Attention:

The lowest power jumper contact is not carried out for some modules (e.g. 4-channel)!

A module which needs all contacts (e.g. 2 channel digital) may not be connected to the

right hand side of modules which do not have 3 power jumper contacts (e.g. 4 channel

modules).

For the digital outputs (without diagnostic) four-conductor devices (V+; 0 V; signal;

ground) are standard. In case of 12 mm wide 4-channel digital output modules it is not

possible to use 4-conductor devices. 4 signal outputs, 2xV+ and 2x0V are provided.

All digital outputs are short-circuit protected.

In case of overloads a supply module with fuse (750-601) must be connected on the

line side to protect the output modules.

The module 750-516 is low-side switching. The indicated output values have been

determined for 100% duty cycle. However, in case of the 2 A versions it is possible to

operate single channels at higher load currents, however always verify that the total

current does not exceed 3.5 A per module. Example: 2x2A (standard); 1x3.0A; 1x0.5A

(total current: 3.5 A) The standard numerical assignment for bus operations is from left

to right, starting with the LSB. The positions of the different I/O modules in the

configured node/station are selectable by the user. A block type configuration is not

necessary.The Output module can be connected to all buscouplers of the

WAGOÇI/OÇSYSTEM.

Digital Outputs (Standard with diagnostics)

PN 750-506

Technical description:

The power supply is provided by a series-connected supply module for the respective

operating voltage. Power connections are made automatically from module to module

via the internal P.J.C.s when snapped onto the DIN rail.

Attention:

The lowest power jumper contact is not carried out for some modules (e.g. 4-channel)!

A module which needs all contacts (e.g. 2 channel digital) may not be connected to the

right hand side of modules which do not have 3 power jumper contacts (e.g. 4 channel

modules).

Using the digital outputs with diagnostic bit outputs (750-506) allows verification of the

I/O channel by the connected bus. Example: a short-circuit at the output or an open

circuit will set the appropriate error bit true indicating I/O failure. In this configuration

the function module includes 2 digital outputs and 2 separate digital inputs. For the

digital outputs with diagnostic four-conductor devices (V+; 0V; signal; ground) are

standard. All digital outputs are short-circuit protected.

In case of overloads a supply module with fuse (750-601) must be connected on the

line side to protect the output modules.

The standard numerical assignment for bus operations is from left to right, starting with

the LSB. The positions of the different I/O modules in the configured node/station are

selectable by the user. A block type configuration is not necessary. When using I/O

modules with diagnostics, the existing inputs must be considered accordingly in the

Digital Outputs (Solid State Relay)

PN 750-509

Technical Description

The power supply for the solid state relay module is connected by a series-connected

supply module for the respective operating voltage of 230 V. Power connections are

made automatically from module to module via the internal P.J.C.s when snapped onto

the DIN rail.

Attention:

The lowest power jumper contact is not carried out for some modules (e.g. 4-channel)!

A module which needs all contacts (e.g. 2 channel digital) may not be connected to the

right hand side of modules which do not have 3 power jumper contacts (e.g. 4 channel

modules).

The power supply of the control side is not made via the power jumper contacts but

directly from the electronics. The respective output contacts of the switching element

are therefore always positioned at the field side. One termination point of these contacts

must be directly connected to the power supply. For the digital outputs four-conductor

devices (V+; 0V; signal; ground) are standard. All digital outputs are short-circuit

protected. In case of overloads a supply module with fuse (750-609) must be

connected on the line side to protect the output modules.

The standard numerical assignment for Bus operation is from left to right, starting with

the LSB. The positions of the different inputs in the configured station are via the user’s

choice. A block type assembly is not necessary. The Output module can be connected to

all buscouplers of the WAGOÇI/OÇSYSTEM.

Pulsewidth Module

PN 750-511

Technical Description:

This description is for hard and software version X X X X 2 B 0 2- - - - . The part

number is displayed on the right side of the module.

The initial pre-programmed base frequency is for 250 Hz. The resolution is 10 Bits and

the pulsewidth is modulated.

Attention:

The lowest power jumper contact is not carried out for some modules (e.g. 4-channel)!

A module which needs all contacts (e.g. 2 channel digital) may not be connected to the

right hand side of modules which do not have 3 power jumper contacts (e.g. 4 channel

modules).

The following description is preliminary and is applicable to the factory configuration.

The pulsewidth output module 750-511 produces a binary modulated signal of 24 V.

The connection of the consuming device should be made via the „O“ and 0 V (common)

contacts of the module. The distribution of the 24 V DC is made via the power jumper

contacts. If galvanic isolation is desired, a new power feed via a 750-602 is required.

The PWM module can be connected to all buscouplers of the WAGOÇI/OÇSYSTEM

(except for the economy type).

Version 1: non-floating (750-512)

The power supply is made via a series-connected supply terminal block for the

respective operating voltage. Power connections are made automatically from module to

module when snapped onto the DIN rail. One termination point of these contacts must

be directly connected to the power supply.

Version 2: isolated outputs (750-513, 750-514)

These I/O modules are not provided with integrated power jumper contacts. Care should

be taken to supply each isolated module with separate power supply connections.

The standard numerical assignment for Bus operation is from left to right, starting with

the LSB. The positions of the different inputs in the configured station are via the user’s

choice. A block type configuration is not necessary. The output module can be

connected to all buscouplers of the WAGOÇI/OÇSYSTEM.

The function module 750-461 allows the direct connection of PT- or Ni-resistance

sensors. The module is suitable for 2- or 3-wire RTDs. Connection is made according to

the above wiring diagram.

Linearization is accomplished over the entire measurement range by a microprocessor.

The temperature ranges of the above listed RTD types is available to the user. The

temperature ranges of the sensors are represented with a resolution of 1 bit per 0.1° C in

one word (16 bits). Resulting from this, 0°C corresponds to the hexadecimal value 0000

and 100°C is 03E8 (dez.1000). Temperatures below 0° are represented in two’s

complement with a leading ‘1’.

The function module works in the defined temperature range for the PT100 sensors of

-200°C to +850°C. The voltage resolution is represented with 16 bits. An A/D

converter and processor converts the voltage value to a numerical value proportional to

the temperature of the selected resistance temperature sensor.

A short circuit or an interruption of the RTD wire is transmitted to the bus module and

indicated by the red error LED. The green LED identifies that the module is

communicating properly with the connected Buscoupler.

All temperature values will be shown in a unit numerical format. If the mode

‘DEFAULT’ is selected each bit corresponds to 0.1°C. The possible numerical range

refers to the standardized temperature range of the used sensors. The following table

The function module 750-462 permits the direct connection of thermocouple sensors.

The module is suitable for 2 or 3-wire thermocouples. For the 2-wire connection

technique, connect the thermocouple wires between TC- and TC+ . For the 3-conductor

technique the shield is also connected. The operation of grounded sensors is provided by

means of internal electrical isolation.

The function module 750-469 alos detects a broken wire. You can find the PNs for the

different sensor types for 750-462 in the following table.

Warning: Both inputs are referenced to a common potential (not isolated)!

The linearization is provided over the complete range by a microprocessor. The

temperature ranges of the sensors are represented with a resolution of 1 bit per 0.1°C in

one word (16 Bit). Thus, 0°C corresponds to the value 0000, and 25.5°C correspond to

the value 0 x 00FF. Temperatures below 0°C are represented in two’s complement with

a leading ‘1’.

Within the whole range of all thermocouples, the function module works like a ‘µV

meter’. The voltage resolution is represented with 16 bits. A processor converts the

voltage value into a numerical value proportional to the measured temperature of the

selected type of thermocouple.

In order to compensate the offset voltage at the clamping point, a cold junction

thermocouple compensation calculation is carried out. The circuit contains a

temperature measuring sensor at the ‘CAGE CLAMP’ connection and considers the

temperature offset voltage when calculating the measured value.

The numerical formats

All temperature values are represented in a uniform numerical format. In the default

setting (type K) one Bit corresponds to 0.1°C. The output value corresponds to the

temperature range of each sensor as defined according to standards. By using a

configuration tool, the output formats can be chosen. The linearization can be switched

off and the building of the reference temperature can be switched off also. The

following table identifies the numerical format on the default range (type K).

Technical Description

After the fieldbus node is assembled with the correct buscoupler and selected I/O

modules, the end module is snapped onto the assembly. It completes the internal data

circuit and ensures correct data flow.

The potential multiplication module allows additional + and - voltage connection points

(up to 4 additional). This eliminates external terminal blocks.

Supply modules

PN750-601, 602, 609, 610, 611, 612, 613, 615

Technical Description

The supply module provides I/O module power through the power jumper contacts.

Maximum current supply to all connected modules is 10 A. Maximum current supply to

the modules with fuse holder is 6.3 A. Should higher currents be necessary, intermediate

supply modules may be added in the assembly.

The modules 750-601, 609, 615, 610 and 611 are additionally equipped with a fuse

holder. The change of the fuse is very easy by drawing out the fuse holder and changing

the fuse. A blown fuse is indicated by a LED.

The modules 750-610 and 611 send information about the status of the supply module

to the fieldbus coupler through two input bits.

Using the supply modules you have to look for the allowed voltage. The following table

shows the voltage for the supply modules.

The supply module 750-613 supplies the field side and te internal databus system

Input

The use of this module in conjunction with a SSI encoder provides direct positional

information rather than the type of data resultant from incremental type encoders.

Absolute encoders are comprised of several data disks which generate a data

word which is unique through out the 360 degrees of rotation. The data format

is a modified binary pattern in either Graycode or Dualcode.

The resolution of the sensor depends upon the configuration of the sensor and

the physical number of revolutions in the motion profile. Since the basis of the

encoder is to provide absolute positional information based upon a mechanical

configuration limited to one revolution or less. The maximum resolution of this

module is 24 bit.

The frequency of the data signal input to the SSI module is maintained at 125 kHz.

Listed below are the recommended cable lengths for the various clock signal Baud

rates.

Operational Characteristics:

The quadrature encoder interface accepts up to two input signals for the counting

increment. The index pulse may also be considered should the control configuration

require. There is also a Latch and Gate input available on the module for added

functionality.

The quadrature encoder provides two signals that are shifted 90 degrees from each

other, signals A and B. In order to achieve a better common mode noise rejection ratio,

the output signals from the encoder are transmitted via a differential signal. Their

complement signals, A(inv.) and B(inv.) are also transmitted. A directional

determination may be made by which signal leads. If the A signal leads, the direction is

considered to be forward. If the B signal leads, the direction is considered to be reverse.

By exchanging the A and A(inv.) the phase relationship will be changed by 180 degrees,

thus allowing the direction to be preset via the wiring configuration.

Most quadrature encoders have an Index signal, or Z rev, as well as the incremental

signal. This signal provides one pulse per revolution with a duration equal to an

incremental pulse.

The inputs to the quadrature encoder module must be supplied from an encoder with

Line Driver Outputs for proper operation. The 5 Volt DC output may be used to power

the encoder. The 24 Volt DC input supply must be provided from an external power

supply.

The Gate and Latch inputs are 24 Volt DC.

It is possible to process and/or check the below listed actions via the control and status

bits.

Extending the 16 bit counting range: The internal counting range is 16 bits or a

maximum value of 65535. Should the application require an extended count range the

location-difference-integration method may be employed. This method uses the control

system to store the interrogated counter value. Any new interrogated value will have the

previously stored counter value subtracted from it. This value will then be added to an

accumulated register value. It is assumed that the counter difference of the two

interrogated values is smaller than 16 bits therefore overflows need not be considered.

Another method calculates the extended counter range via the underflow and overflow

status bits. The interrogated value is either added or subtracted to the accumulation

Set Counter Position: The presetting of the counter is possible via the CNT_SET bit.

The desired preset is loaded into the data register and the CNT_SET bit is set from 0 to

1. The CNTSET_ACC bit will be set to 1 when the preset value is loaded into the count

Maintaining the Present Counter Position: The counter present value may be

maintained or latched via the external Latch input. First the external latch must be

enabled via the EN_LATEXT bit. Once the input is enabled, the data will be latched

into the counter module upon a 0 to 1 transition. Upon completion of the latch process

the external latch valid bit LATEXT_VAL will be set to 1.

Maintaining a Reference Point: The storage of a present counter value may also

accomplished via the Index pulse from the encoder. First the index latch enable bit must

be set, EN_LACT, to a value 1. The counter present value will be latched upon the low

to high transition of the Index input. Upon completion of the data latch process the

Index Latch Valid bit, LACT_VAL will be set to 1.

Description of RS 232:

The interface module is designed to operate with all WAGO I/O fieldbus couplers. The

serial interface module allows the connection of RS 232-Interface devices to the WAGO

I/O SYSTEM. The RS 232 Interface module can provide gateways within the fieldbus

protocol. This allows serial equipment such as printers, barcode readers, and links to

local operator interfaces to communicate directly by thefieldbus protocol with the PLC

or PC Master.

This module supports no higher level of protocol. Communication is made completely

transparent to the fieldbus allowing flexibility in further applications of the serial

interface module. The communication protocols are configured at the Master PLC or

PC.

The 128 byte input buffer provides for high rates of data transmission. When using

lower rates of transmission speed you can collect the received data, with less priority,

without loosing data.

The 16 byte output buffer provides for faster transmission of larger data strings.

FUNCTION

The data transmission takes place at 9.600 baud (default value). 1 startbit, 8 databits and 1

stopbit will be transmitted. No parity is available. The user controls data via the RTS and

CTS signals. These signals are generated in the module depending on the loading status of

the buffers. These controls can be deactivated by means of an external jumper. RTS and

CTS are to be connected.

For testing purposes the Windows 3.11 terminal emulation can be used. A cable with a 9-

pole sub-D socket is required. Pin 5 is connected to input M. Pin 2 is connected to TxD and

Pin 3 to RxD. RTS and CTS of the module are connected. A hardwarehandshake between

terminal emulation and SPS is not possible though.

Description of data exchange module

The data exchange module allows the exchange of 4 (5) bytes between different fieldbus

systems via multiplexing of a serial connection. The delay which is caused by the

multiplexor is < 5ms. The integrated watchdog function switches all outputs to zero if

there is no valid information for more than 200 ms via the multiplex connection.

The 128 bytes input buffer provides for high rates of data transmission. When using

lower rates of transmission speed you can collect the received data, with less priority,

without loosing data.

The 16 byte output buffer provides for faster transmission of larger data strings.

The data exchange module is connected peer-to-peer. For the wiring of the serial

multiplex connection the RxD and TxD cables are crossed. The following illustrations

show the peer-to-peer connection and the internal structure of the data exchange

module.

Structure of input and output data:

The module is a combined special function input and output module with 1 x 32 (40) Bit

input and output data. The tranfer of the data to be transmitted and the received data is

made via up to 5 input and 5 output Bytes. One control byte and one status byte are used

to control the floating data.

The control byte consists of the following bits:

The PLC is able to control transmission and reception of data by means of the control

byte and the status byte.

Control of the multiplex connection: In the process image of the transmitting

buscoupler one Bit is set to „1“ for the whole time. As long as this Bit is „1“ in the

receiving coupler, further input Bits can be evaluated. If the Bit is „0“ the multiplex

connection has been disrupted. The further Bits are also 0 because of the watchdog.

Control of the multiplex connection with acknowledge: If the transmitting

buscoupler gets an acknowledge from the receiving buscoupler, the received bit must be

transfered as an output bit to the process image. The transmission is successful as long

as the Bit is „1“.

Handshake: If a serial data exchange should be made with the data exchange module,

the handshake can be made via „Toggle Bits“. Therefore an input bit and an output bit

are reserved. As soon as those bits are different from each other, a request from the

opposite module is made. As soon as the request is executed the output bit is toggled.

Application in Explosive Environments

Foreword

• 1

Ex-1 Application in Explosive Environments

Ex-1.1 Foreword

Today’s development shows that many chemical and petrochemical

companies have production plants, production, and process automation

machines in operation which use gas-air, vapor-air and dust-air mixtures

which can be explosive. For this reason, the electrical components used in

such plants and systems must not pose a risk of explosion resulting in injury to

persons or damage to property. This is backed by law, directives or

regulations, on a national and international scale. WAGO-I/O-SYSTEM 750

(electrical components) is designed for use in zone 2 explosive environments.

The following basic explosion protection related terms have been defined.

Ex-1.2 Protective measures

Primarily, explosion protection describes how to prevent the formation of an

explosive atmosphere. For instance by avoiding the use of combustible

liquids, reducing the concentration levels, ventilation measures, to name but a

few. But there are a large number of applications, which do not allow the

implementation of primary protection measures. In such cases, the secondary

explosion protection comes into play. Following is a detailed description of

such secondary measures.

Ex-1.3 Classification meeting CENELEC and IEC

The specifications outlined here are valid for use in Europe and are based on

the following standards: EN50... of CENELEC (European Committee for

Electrotechnical Standardisation). On an international scale, these are reflected

by the IEC 60079-... standards of the IEC (International Electrotechnical

Commission).

Ex-1.3.1 Divisions

Explosive environments are areas in which the atmosphere can potentially

become explosive. The term explosive means a special mixture of ignitable

substances existing in the form of air-borne gases, fumes, mist or dust under

atmospheric conditions which, when heated beyond a tolerable temperature or

subjected to an electric arc or sparks, can produce explosions. Explosive zones

have been created to describe the concentrations level of an explosive

atmosphere. This division based on the probability of an explosion occurring

is of great importance both for technical safety and feasibility reasons,

knowing that the demands placed on electrical components permanently

employed in an explosive environment have to be much more stringent than

those placed on electrical components that are only rarely and, if at all, for

short periods, subject to a dangerous explosive environment.

Application in Explosive Environments

Classification meeting CENELEC and IEC

Explosive areas resulting from gases, fumes or mist:

• Zone 0 areas are subject to an explosive atmosphere

(> 1000 h /year) continuously or for extended periods.

• Zone 1 areas can expect the occasional occurrence of an explosive

atmosphere (> 10 h ≤ 1000 h /year).

• Zone 2 areas can expect the rare or short-term occurrence of an explosive

atmosphere (> 0 h ≤ 10 h /year).

Explosive areas subject to air-borne dust:

• Zone 20 areas are subject to an explosive atmosphere

(> 1000 h /year) continuously or for extended periods.

• Zone 21 areas can expect the occasional occurrence of an explosive

atmosphere (> 10 h ≤ 1000 h /year).

• Zone 22 areas can expect the rare or short-term occurrence of an explosive

atmosphere (> 0 h ≤ 10 h /year).

Ex-1.3.2 Explosion protection group

In addition, the electrical components for explosive areas are subdivided into

two groups:

Group I:

Group I includes electrical components for use in fire-damp

endangered mine structures.

Group II:

Group II includes electrical components for use in all other

explosive environments. The group is further subdivided by

pertinent combustible gases in the environment.

Subdivision IIA, IIB and IIC takes into account that

different materials/substances/gases have various ignition

energy characteristic values. For this reason the three sub-

groups are assigned representative types of gases:

• IIA – Propane

• IIB – Ethylene

• IIC – Hydrogen

Ex-1.3.4 Temperature classes

The maximum surface temperature for electrical components of explosion

protection group I is 150 °C (danger due to coal dust deposits) or 450 °C (if

there is no danger of coal dust deposit).

In line with the maximum surface temperature for all ignition protection types,

the electrical components are subdivided into temperature classes, as far as

electrical components of explosion protection group II are concerned. Here the

temperatures refer to a surrounding temperature of 40 °C for operation and

testing of the electrical components. The lowest ignition temperature of the

existing explosive atmosphere must be higher than the maximum surface

temperature.

explosive atmospheres can only be expected to occur rarely or short-term. It

represents the transition between the area of zone 1, which requires an

explosion protection and safe area in which for instance welding is allowed at

any time.

Regulations covering these electrical components are being prepared on a

world-wide scale. The standard EN 50 021 allows electrical component

manufacturers to obtain certificates from the corresponding authorities for

instance KEMA in the Netherlands or the PTB in Germany, certifying that the

tested components meet the above mentioned standards draft.

Type “n” ignition protection additionally requires electrical components to be

marked , with the following extended identification:

• A – non spark generating (function modules without relay /without

switches)

• AC – spark generating, contacts protected by seals (function modules with

relays / without switches)

• L – limited energy (function modules with switch)

Danger

For the use of WAGO-I/O SYSTEM 750 (electrical operating means) with Ex

approval the observance of the following points is mandatory:

• The electrical operating means are exclusively suitable for applications in

explosion endangered areas (Europe Group II, Zone 2 or America: Class I,

Division 2, Group A, B, C, D) or in non explosion endangered areas!

• Ensure that only approved modules of the electrical operating means will

be used. Replacement of components can jeopardize the suitability of the

system in explosion endangered zones!

• Only disconnect and/or connect electrical operating means when the

voltage supply is isolated or when a non-explosive atmosphere has been

ascertained!

• Adhere to the specified data regarding voltage supply and fusing. (See

data on the fuse holder)!
