Modbus RTU/ Modbus ASCII Description
The Modbus RTU and Modbus ASCII drivers allow the FieldServer to transfer data to and from
devices over either RS-232 or RS-485 using Modbus RTU or Modbus ASCII protocol
respectively. The driver was developed for Modbus Application Protocol Specification V1.1a"
emulate either a Server or Client.
The information that follows describes how to expand upon the factory defaults provided in the
configuration files included with the FieldServer.
There are various register mapping models being followed by various vendors
To cover all these models FieldServer uses the following three Models
•
Modicon_5digit – Use this format where addresses are defined in 0xxxx, 1xxxx, 3xxxx or
4xxxx format. A maximum of 9999 registers can be mapped of each type. This is
FieldServer driver’s default format.
•
•
ADU –Application Data Unit address. Use this format where addresses of each type are
defined in the range 1-65536
PDU –Protocol Data unit address. Use this format where addresses of each type are
defined in the range 0-65535.
The key difference between ADU and PDU is for example if Address_Type is ADU and address
is 1, the driver will poll for register 0. If Address_Type is PDU, the driver will poll for address 1.
Note 1: If vendor document shows addresses in extended Modicon (i.e. 6 digit) format like
4xxxxx then consider these addresses as xxxxx (omit the first digit) and use either ADU or PDU
Note 2: The purpose of providing 3 different ways of addressing the Modbus registers is to allow
the user to choose the addressing system most compatible with the address list being used. At
the protocol level, the same protocol specification is used for all three with the exception of the
limited address range for Modicon_5digit.

Hardware Connections
It is possible to connect a Modbus RTU or Modbus ASCII device to any of the existing serial
ports on the FieldServer1. These ports simply need to be configured for the appropriate driver in
the configuration file.
Configure the Modbus RTU or Modbus ASCII device according to manufacturer’s instructions.

Configuring the FieldServer as a Modbus RTU or Modbus ASCII Client.
For a detailed discussion on FieldServer configuration, please refer to the FieldServer
Configuration Manual. The information that follows describes how to expand upon the factory
defaults provided in the configuration files included with the FieldServer (See “.csv” sample files
provided with the FieldServer).
This section documents and describes the parameters necessary for configuring the FieldServer
to communicate with a Modbus RTU or Modbus ASCII Server.
4.1.
Data Arrays/Descriptors
The configuration file tells the FieldServer about its interfaces, and the routing of data
required. In order to enable the FieldServer for Modbus RTU or Modbus ASCII
communications, the driver independent FieldServer buffers need to be declared in the
“Data Arrays” section, the destination device addresses need to be declared in the “Client
Side Nodes” section, and the data required from the Servers needs to be mapped in the
“Client Side Map Descriptors” section. Details on how to do this can be found below.
Note that in the tables, * indicates an optional parameter, with the bold legal value being the
default.

Appendix A.2. Single Writes
For pure write operations where the function = WRBC or WRBX, the driver defaults to using
Function Codes 15 and 16 (Multiple writes). It is possible to force the driver to use Function
Codes 5 and 6 (Single Writes) by manipulating the Data_Type parameter as follows:
For Address_Type ADU:
Address range Data_Type
Function Code (Write)
1 - 65536

6
5.
Example: FC 6 = Write Single Register
Add a parameter to the Modbus client side Map Descriptor called Data_Type.
If you specify the Data_Type as Single_Register and the Function as WRBC or WRBX,
then a Modbus poll with FC 6 will be generated.
Logically Single Register implies a length of one, and even if you try to set the length longer
in the csv file, the length is limited to 1 in the driver.
Appendix A.3. Read/write Operation
When using the driver as a Modbus master, the function RDBC allows read/write capability
with Register and Coil data types. If defaults are used, then Function codes 5 and 6 (Single
Writes) are used to write data back to the registers being read, regardless of data length
being read. If multiple writes (FC 15 and 16) are needed for Read/write operation, the user
needs to specify the Node_Type parameter in the Client Side Nodes Section and set it to
Block_Mode.
Note that block writes of length 1 are currently all that is supported.

Transferring 32 bit values with two registers
Page 18 of 21
If a Modbus Server sends two consecutive registers to the FieldServer representing either a
floating point value or a 32 bit integer value, the FieldServer can combine and decode these
registers back into their original format. To do this, the user must read the registers into an
integer data array, and then use the Moves function to move the data to a floating point or
32 bit integer data array. The “function” field in the move must be populated with the correct
move function required. Details of the available function fields are listed in the FieldServer
configuration manual along with a more detailed explanation of moves. Note that functions
also exist to split a floating point value into two integers using the reverse operation.
A diagrammatic representation of this process is depicted below:

that were placed in an integer data array.

Moves
Function,

This Move will cause two integers at offsets 0 and 1 in the integer Data Array DA1 to be
copied to offset 6 in the float Data Array DA2. In the process of copying the values, the
integers will be combined and treated as an IEEE 32 bit floating point number.
Appendix A.5. Connection to York Modbus Microgateway
If connecting the FieldServer to a York Modbus Microgateway, the Node_ID of the
Microgateway is defined by the address DIP switches. If switch 4 is set to ‘On’ and the other
switches are set to ‘off’ then Node_ID of the Microgateway is ‘247’, the parity is ‘Even’, and
the stop bits are 1. Other Node_ID combinations can be found in the York Modbus
Microgateway Installation Manual.

Appendix A.6. Node_Offline_Response
This function is specific to the Modbus RTU driver.
In systems where data is being collected from multiple Server Nodes and made available on
a FieldServer configured as a Modbus RTU Server, when a Server Node goes offline the
default behavior of the FieldServer would be to stop responding to polls for this data. This
might not be what the user wants. Various options exist making it possible to signal that the
data quality has gone bad without creating error conditions in systems sensitive to the
default option.
The following
options
can
be configured
under the Node
parameter,
Node_Offline_Response, to set the response of the FieldServer to the Modbus RTU Client
when the Server Node supplying the data is offline:
•
•
No_Response - this is the default option. The FieldServer simply does not respond when
the corresponding Server Node is offline.
Old_Data - The FieldServer will respond, but with the last known value of the data. This
maintains the communication link in an active state, but may hide the fact that the Server
Node is offline.
•
•
Zero_Data - The FieldServer will respond, but with the data values set to zero. If the
user normally expects non-zero values, this option will signal the offline condition without
disrupting communications.
FFFF_Data - The FieldServer will respond, but with the data values set to FFFF (hex). If
the user normally expects other values, this option will signal the offline condition without
disrupting communications.
