1.1
UNPACKING PROCEDURE
1. Remove the Profile Controller from its packing. The Controller is
supplied with a panel gasket and push-fit fixing strap. Retain the
packing for future use, should it be necessary to transport the Profile
Controller to a different site or to return it to the supplier for
repair/testing.
2. Examine the delivered items for damage or deficiencies. If any is
found, notify the carrier immediately.
1.2
PANEL-MOUNTING THE CONTROLLER
The panel on which the Profile Controller is to
be mounted must be rigid and may be up to
6.0mm (0.25 inches) thick. The cut-out required
for a single Profile Controller is as shown in
Figure 1-1.
Several instruments may be installed in a single
cut-out, side-by-side. For n Profile Controllers
mounted side-by-side, the width of the cut-out
would be:
45m m +0.5 -0.0
Figure 1-1
(48n - 4) millimetres or (3.78n - 0.16) inches.
The Profile Controller is 110mm deep (measured from the rear face of the front
panel). The front panel is 48mm high and 48mm wide. When panel-mounted, the
front panel projects 10mm from the mounting panel. The main dimensions of the
Profile Controller are shown in Figure 1-2.

The procedure to panel-mount the Profile Controller is shown in Figure 1-3.
CAUTION: Do not remove the panel gasket, as this may result in
inadequate clamping of the instrument in the panel.
NOTE: When installing several instruments side-by-side in one
cut-out, use the ratchets on the top/bottom faces.

2.1.
1.3
CONNECTIONS AND WIRING
The rear terminal connections are illustrated in Figure 1-4.
This instrument is designed for installation in an enclosure
which provides adequate protection against electric shock.
All pertinent local regulations should be rigidly observed.
Consideration should be given to prevention of access to the
rear terminals by unauthorised personnel.

1.3.1
Mains (Line) Input
The Profile Controller will operate on 96 - 264V AC 50/60Hz mains (line) supply.
The power consumption is approximately 4 VA. Power should be connected via a
two-pole isolating switch (preferably situated near the equipment) and a 1A fuse.
If the Profile Controller has relay outputs in which the contacts are to carry mains
(line) voltage, it is recommended that the relay contact mains (line) supply should
be switched and fused in a similar manner but should be separate from the Profile
Controller mains (line) supply.
1.3.2
24V (Nominal) AC/DC Supply
The supply connections for the 24V AC/DC option of the Profile Controller are as
shown in Figure 1-4. Power should be connected via a two-pole isolating switch
and a 315mA slow-blow (anti-surge Type T) fuse.
With the 24V AC/DC supply option fitted, these terminals will accept the following
supply voltage ranges:
24V (nominal) AC 50/60Hz -
24V (nominal) DC -
20 - 50V
22 - 65V
1.3.3
Thermocouple Input
The correct type of thermocouple extension leadwire or compensating cable must
be used for the entire distance between the Profile Controller and the
thermocouple, ensuring that the correct polarity is observed throughout. Joints in
the cable should be avoided, if possible. The CJC facility must be enabled (normal
conditions) for this input (see Subsection 3.4).
NOTE: Do not run thermocouple cables adjacent to power-carrying
conductors. If the wiring is run in a conduit, use a separate conduit for the
thermocouple wiring. If the thermocouple is grounded, this must be done
at one point only. If the thermocouple extension lead is shielded, the shield
must be grounded at one point only.
1.3.4
RTD Inputs
The compensating lead should be connected to Terminal 4. For two-wire RTD
inputs, Terminals 4 and 5 should be linked. The extension leads should be of
copper and the resistance of the wires connecting the resistance element should
not exceed 5 ohms per lead (the leads should be of equal resistance).

S077-1
1.3.5
Linear Inputs
For linear mA input ranges, connection is made to Terminals 4 and 6 in the
polarity shown in Figure 1-4. For linear mV and V ranges, connection is made to
Terminals 4 and 5 in the polarity shown in Figure 1-4. For details of the linear
input ranges available, refer to Appendix A.
1.3.6
Remote Run/Hold Input
With this option fitted, Terminals 11 and 12 are used for external Run/Hold
control of the currently-selected program; this has an effect identical to that of the
front panel RUN key. These terminals may be connected to (a) the voltage-free
contacts of a switch or relay, or (b) a TTL-compatible voltage. This is an
edge-sensitive input for which the following convention has been adopted:
For TTL input, OFF = logic 1 and ON = logic 0
For a voltage-free input, OFF = open and ON = closed
Program control is as follows:
OFF-ON transition:
ON-OFF transition:
The currently-selected program will run (or
will resume running if it is currently held).
The currently-running program will be
held.
NOTE: When this input is used, the front panel RUN key can be
used only to abort a program. Powering-up the Profile Controller
whilst this input is ON will not cause a program to run. The RS485
Serial Communications option and the Remote Run/Hold option are
mutually exclusive.
1.3.7
Relay Outputs
The contacts are rated at 2A resistive at 120/240V AC.
1.3.8
SSR Drive Outputs
These outputs produce a time-proportioned non-isolated DC signal (0 - 4.2V
nominal into 1kW minimum).
1.3.9
Solid State Outputs
These outputs provide up to 1A AC drive with a longer lifetime than an
electromechanical relay. For further details, refer to Appendix A.

1.3.10 DC Outputs
See Appendix A.
1.3.11 RS485 Serial Communications Link
The cable used should be suitable for data transfer at the selected rate (1200,
2400, 4800 or 9600 Baud) over the required distance. Transmitters/receivers
conform to the recommendations in the EIA Standard RS485.
The “A” terminal (Terminal 11) on the Profile Controller should be connected to
the “A” terminal on the master device; the “B” terminal (Terminal 12) on the
Profile Controller should be connected to the “B” terminal on the master device.
Where several Profile Controllers are connected to one master port, the master
port transceiver in the active state should be capable of driving a load of 12kW per
Profile Controller; the master port transceiver in the passive state must have
pull-up/pull-down resistors of sufficiently low impedance to ensure that it remains
in the quiescent state whilst supplying up to ±100mA each to the Profile Controller
transceivers in the high impedance state.
NOTE: The RS485 Serial Communications option and the Remote
Run/Hold option are mutually exclusive.

2.1
REMOVING THE PROFILE CONTROLLER FROM ITS
HOUSING
CAUTION: Before removing the instrument from its housing, ensure
that all power has been removed from the rear terminals.
To withdraw the instrument from its housing, simply grip the side edges of the
front panel (there is a finger grip on each edge) and pull the instrument forwards.
This will release the instrument from its rear connectors in the housing and will
give access to the instrument PCBs. Take note of the orientation of the instrument
for subsequent replacement into the housing.The positions of the PCBs in the
instrument are shown in Figure 2-1.

REMOVING/REPLACING THE OUTPUT 2/OUTPUT 3 OPTION
PCBs
With the instrument removed from its housing:
1. Gently push the rear ends of the CPU PCB and Power Supply PCB apart
slightly, until the two tongues on each of the Output 2/Output 3 Option
PCBs become disengaged - see Figure 2-2B; The Output 2 Option PCB
tongues engage in holes in the Power Supply PCB and the Output 3 Option
PCB tongues engage in holes on the CPU PCB.
2. Carefully pull the required Option PCB (Output 2 or Output 3) from its
connector (Output 2 Option PCB is connected to the CPU PCB and Output
3 Option PCB is connected to the Power Supply PCB) - see Figure 2-2C.
Note the orientation of the PCB in preparation for its replacement.
Adjustments may now be made to the link jumpers on the CPU PCB, the Output
2/Output 3 Option PCBs (if DC output) and (if fitted) the DC Output 1 PCB. The
replacement procedure is a simple reversal of the removal procedure.
2.3
REMOVING/REPLACING THE RS485 COMMUNICATIONS
OPTION PCB OR REMOTE RUN/HOLD OPTION PCB
The RS485 Communications Option PCB or Remote Run/Hold Option PCB is
mounted on the inner surface of the Power Supply PCB and can be removed when
the instrument is removed from its housing (see Subsection 2.1) Figure 2-3
illustrates the removal/replacement procedure. It is not necessary to remove the
Output 2/Output 3 Option PCBs to perform this procedure.
2.4
REPLACING THE INSTRUMENT IN ITS HOUSING
To replace the instrument, simply align the CPU PCB and Power Supply PCB with
their guides and connectors in the housing and slowly but firmly push the
instrument into position.
CAUTION: Ensure that the instrument is correctly orientated. A stop
will operate if an attempt is made to insert the instrument in the
wrong orientation (e.g. upside-down). This stop must not be
overridden.

NOTES:
1. If Output 2 is a relay/SSR drive/solid state output, it may be a control
output (COOL), an event output or an alarm output; if it is set to be a DC
output, it can only be a control output (COOL).
2. If Output 3 is a relay/SSR drive output (it cannot be a solid state output),
it can only be an event output or an alarm output; if it is set to be a DC
output, it can only be a recorder (i.e. retransmitted process variable or
setpoint) output.
The maximum setting available for this code is 4887. For example, the code for a
thermocouple input, DC 4 - 20mA primary output (Output 1) and relay Output 3
would be 2701.
NOTE: It is essential that this code is changed promptly
whenever there is a change to the instrument’s hardware
configuration (change of input/output type, alarm/recorder
output added/removed etc.). The instrument software depends
upon this code to ensure that the instrument operates
correctly.
This code may be viewed as a Read Only display in Base Mode (see Volume II,

116-DIN RAMP/SOAK PROFILE CONTROLLER
PRODUCT MANUAL
VOLUME II
OPERATING INSTRUCTIONS
In normal operation, the operator must not remove the Ramp/Soak
Profile Controller from its housing or have unrestricted access to the
rear terminals, as this would provide potential contact with hazardous
live parts.
Installation and configuration must be undertaken only by
technically-competent servicing personnel. This is covered in Volume I
of this manual.

PUTTING A PROGRAM IN HOLD
A program can be put in Hold (i.e. frozen) at any time whilst it is running. The
program setpoint will stay at its value at the instant the program entered Hold
until the program is released (see Subsection 1.4) or aborted (see Subsection 1.5).
To put a program in hold, momentarily press the RUN key. The RUN indicator
will flash whilst the program is in hold.
1.4
RELEASING A PROGRAM FROM HOLD
To release a program currently in Hold, momentarily press the RUN key. The
RUN indicator will then go ON continuously.
1.5
ABORTING A PROGRAM
To abort the current-running (or held) program, hold down the RUN key for 5
seconds. The program will be aborted, the RUN indicator will go OFF and the
normal Controller functions will be resumed.

NOTE: When a program is aborted, the instrument returns to the Controller
Setpoint value. If a program is successfully completed, the Controller
Setpoint is automatically set to the final setpoint value of the program. If it
is desired to restore the initial Controller Setpoint value after the program
is completed, this value should be used as the program Final Setpoint
value.

RaPID CONTROL FEATURE
The RaPID control feature may be used when extra fast responses and minimum
overshoot are required. The RaPID feature works best when PID terms are
well-tuned; therefore, it is recommended that the Pre-Tune feature (see
Subsection 1.8) is run before the RaPID feature is engaged.
Press simultaneously twice
in quick succession
To disengage RaPID control, use the same key actions. NOTE: The RaPID feature
cannot be engaged if Proportional Band 1 or Proportional Band 2 is set to 0. For a
more detailed description of the RaPID feature, refer to Appendix C.
1.8
PRE-TUNE FEATURE
This facility may be used to provide initial tuning of the Profile Controller’s PID
parameters. Pre-Tune may be engaged (and subsequently disengaged) as follows:
NOTE: The Pre-Tune facility will not engage if (a) a program is currently
running, (b) the process variable is within 5% of input span of the setpoint,
or (c) an erroneous key sequence is used. Pre-Tune is a single-shot process
which automatically disengages itself when completed.

3.2
CREATING A PROGRAM
A program is created in two steps:
1. Define the segments of your program; the parameters used depend on
what Program Mode has been configured - Rate Mode (see Subsection
3.2.2) or Time Mode (see Subsection 3.2.3). The segment definitions
determine whether the selected segment is a Ramp Segment, a Soak
Segment or an End Segment.
2. Set the required Program Options (see Subsection 3.2.4). These
determine:
(i) The number of cycles performed by the program,
(Ii) The timebase to be used (hours/minutes or minutes/seconds)
(Iii) The width of the Guaranteed Soak Band (if enabled),
(Iv) The state of the event indicator for each segment in the
program,
(v) The lock code to be used for subsequent entries into Program
Define Mode.
3.2.1
Basic Guidelines
1. The Ramp/Soak Profile Controller may contain up to four programs.
2. Each program may comprise up to 16 segments.
3. Each segment may be:
(a) a Ramp Segment (setpoint changing at a defined rate or between
the initial value and a pre-determined final value over a defined
time),
(b) a Soak Segment (setpoint constant for a defined time,) or
(c) an End Segment (marking the end of the program).
4. A program may contain only one End Segment (the last segment in the
program).
5. If the program comprises 16 segments, Segment 16 is automatically an
End Segment.

Segment Event Status
For every segment in a program there is an event indicator. This may be set ON
or OFF for that segment. The status for the segments in the currently-selected
program appears in the following form in the upper display:
DISPLAY 1
ON
ON
OFF
OFF
DISPLAY 2
ON
ON
OFF
OFF
The first display shows the current event status for Segments 1 - 8 and the second
display shows the current event status for Segments 9 - 16. Each event marker
may be set ON (Up key) or OFF (Down key) in order of segment number. Only the
event indicators for the segments in the program are displayed. If the program
has less than 16 segments (including the End Segment), the non-applicable
display positions are blank; if the program has eight segments or less, the second
display is not included.. The lower display shows the current segment number.
Thus, the key sequence to define the event markers for Segments 1 - 8 could be:

4 MODBUS COMMUNICATIONS
4.1
INTRODUCTION
This Section specifies the MODBUS communications protocol as implemented on
1
the -DIN Ramp/Soak Profile Controller.
16
Certain restrictions have been imposed upon this implementation:
(i) Baud rates may be set to 1200, 2400, 4800 and 9600 only
(ii) Support for multi-parameter Writes is limited to support of the
Multi-word Write Function (Number 16) but will permit writing of one
parameter only per message
(iii) The multi-parameter Read function supports a maximum of 10
parameters in one message.
4.2
MODBUS FUNCTIONS SUPPORTED
In the following list, the original Gould MODBUS function names have been used,
followed by the JBUS names in italics, where such an equivalence exists. The
MODBUS Function number follows the names.
A
B
C
D
E
Read Coil Status (Read n Bits)
01/02
03/04
05
Read Holding Registers (Read n Words)
Force Single Coil (Write 1 Bit)
Preset Single Register (Write 1 Word)
Loopback Diagnostic Test
06
08
F
Preset Multiple Registers (Write n Words)
16
The instrument will identify itself in reply to a Read Holding Registers message
which enquires the values of parameter numbers 121 & 122, as specified in the
CNOMO documentation, and MODBUS Function 17 (Report Slave ID) will not be
supported.
4.3
MESSAGE FORMATS
The first character of every message is an instrument address. The valid range of
such an address is 0 to 255. The second character is always the Function
Download from Www.Somanuals.com. All Manuals Search And Download.
Volume II
O077-4
4-1
Number. The contents of the remainder of the message depends upon the
function number.
In most cases the instrument is required to reply by echoing the address and
function number, together with an echo of all or part of the message received (in
the case of a request to write a value or carry out a command) or the information
requested (in the case of a read parameter operation). Broadcast Messages (to
which the controller responds by taking some action without sending back a reply)
are supported at instrument address zero. Commands which can be broadcast
are marked with the symbol B.
Data is transmitted as eight-bit binary bytes with 1 start bit, 1 stop bit and
optional parity checking (None, Even or Odd).
A message is terminated solely by a delay of more than three character lengths at
the given Baud Rate, and any character received after such a delay is treated as a
potential address at the start of a new message.
The following individual message formats apply. Since only the RTU form of the
protocol is being supported, each message is followed by a two-byte CRC16.
Details of how the checksum must be calculated are given at the end of this
section.
A.
Read Coil Status (Read n Bits)
01/02
The message sent to the controller will consist of 8 bytes, as follows:
Addr. of
1st Bit
Addr. Func.
No. of bits
HI LO
CRC16
HI LO
1/2
HI
LO
The normal reply will echo the first two characters of the message received, and
will then contain a single-byte data byte count, which will not include itself or the
CRC. For this message, there will be one byte of data per eight bits-worth of
information requested, with the LSbit of the first data byte transmitted depicting
the state of the lowest-numbered bit required.
Addr. Func.

O077-4
This function will be used largely to report controller status information, and so a
bit set to 1 indicates that the corresponding feature is currently enabled/active,
and a bit reset to 0 indicates the opposite.
If an exact multiple of eight bits is not requested, the data is padded with trailing
zeros to preserve the 8-bit format. After the data has been transmitted, the
CRC16 value is sent.
B.
Read Holding Registers (Read n Words)
03/04
The message sent to the controller to obtain the value of one or more registers is
an eight-byte message as follows:
Addr. of
1st Word
Addr. Func.
No. of words
HI LO
CRC16
HI LO
3/4
HI
LO
The reply sent by the controller echoes the first 2 characters received and then
contains a single-byte data byte count, the value of which does not include either
itself or the CRC value to be sent. For this message, the count equals the number
of parameters read times two. Following the byte count, that number of
parameter values are transmitted, MSB first, followed by the CRC16.
Addr. Func.

HI LO
2nd value
HI LO

C.
Force Single Coil (Write 1 Bit)
05 B
The message received by the controller is 8 bytes long, consisting of the standard
preamble and the address of the bit to force, followed by a two-byte word whose
MSB contains the desired truth value of the bit expressed as 0xFF (TRUE) or 0x00
(FALSE).
Addr. of Bit

Generally, this function will be used to control such features as Auto/Manual and
Tuning.
The normal reply sent by the controller will be a byte-for-byte echo of the
message received.

Volume II
O077-4
4-3
D.
Preset Single Register (Write 1 Word)
06 B
The message sent to the controller consists of 8 bytes: the address and function
number as usual, the address of the parameter to be written, and the two-byte
value to which the parameter will be set, and finally the CRC16.
Addr. of Word
Addr. Func.

HI LO
CRC16

The normal response is to echo the message in its entirety.
E.
Loopback Diagnostic Test

The controller is sent an 8 byte message consisting of the usual preamble, a
two-byte diagnostic code, and two bytes of data, followed by the CRC16.
Diag. Code
HI LO
Addr. Func.
Value
HI LO
CRC16
HI LO

Full MODBUS support in this area is not appropriate - consequently, the only
Diagnostic Code supported is code 00. In response to the message, the controller
must echo the message received exactly.
F.
Preset Multiple Registers (Write n Words) 16 B
This message consists of eleven bytes. Only one parameter may be written at a
time, even though this function number is supported. The preamble is followed
by the address of the parameter to be written, and then a two-byte word count
(always set to 1) and a single-byte byte count (always set to 2). Finally, the value
to be written is followed by the CRC16.

G.
Error and Exception Responses
If the controller receives a message which contains a corrupted character (parity
check fail, framing error etc.), or if the CRC16 check fails, the controller ignores
the message. If the message is otherwise syntactically flawed (e.g. the byte count
or word count is incorrect) the controller will also not reply.
However, if the controller receives a syntactically correct message which
nonetheless contains an illegal value, it will send an exception response,
consisting of five bytes as follows:
Exception No.
Addr. Func.
CRC16
The Function Number field consists of the function number contained in the
message which caused the error, with its top bit set (i.e. function 3 becomes
0x83), and the Exception Number is one of the codes contained in the following
table:
Code
1

CRC16 Calculation
This is a 16-bit cyclic redundancy checksum. It is calculated in accordance with a
formula which involves recursive division of the data by a polynomial, with the
input to each division being the remainder of the results of the previous one.
The formula specifies that input is treated as a continuous bit-stream binary
number, with the most significant bit being transmitted first. However, the
transmitting device sends the least significant bit first.
According to the formula, the dividing polynomial is 216 + 215 + 22 + 1 (Hex
18005), but this is modified in two ways:
i. Because the bit-order is reversed, the binary pattern is reversed also,
making the MSB the rightmost bit, and
Download from Www.Somanuals.com. All Manuals Search And Download.
Volume II
O077-4
4-5
ii. Because only the remainder is of interest, the MSB (the rightmost bit)
may be discarded.
This means the polynomial has the value Hex A001. The CRC algorithm is as
follows:
XOR 1st 8 bits
Pre-load 16-bit
of data with MSB
result with 0x0FF

XOR next 8 bits of

Some of the parameters which do not apply to a particular instrument
configuration (e.g. PB2 on a single output instrument) will accept reads & writes.
Others will accept reads only, and will return an exception if an attempt is made
to write values to them. The values read will in all cases be undefined. It is the
user’s responsibility to make sure that values read reflect a possible state of the
instrument.

RaPID Control Feature
The RaPID (Response - assisted PID) feature offers dramatic improvements in control
quality compared with conventional PID techniques. It responds much more effectively
than PID techniques to load conditions. With this feature, the instrument's response at
start-up, during setpoint changes and during disturbances shows considerably reduced
overshoot and much more shorter settling times (see below).

RaPID works best with well-tuned terms. It is therefore recommended, on newly in-
stalled instruments, that the Pre-Tune facility is run before RaPID is engaged.
Note: If Pre-Tune and RaPID are both engaged, Pre-Tune will run first. Once Pre-Tune
(a single shot process) is automatically disengaged, RaPID will operate automatically.
The responses to RaPID being engaged are:
