This key is enabled by default. It enables or disables the intermodule bus over Eth-

ernet discovery feature. When discovery is disabled (the value is set to 0), software

tools will not discover the device.

This record is not in the setup.csv file by default. To use this feature, add this key and

Modbus®

TCP

Server

Full file name / path where the Modbus® TCP field bus gateway file

lives. This file associates Modbus® TCP registers with data points

from any of the four local busses.

Setup Key: Modbus® TCP

The RMA PLUS is a Modbus® TCP server and provides up to three (priority based) Modbus® TCP sessions. This ser-
vice is enabled by default for all model numbers. It may be disabled by writing “No” to the Modbus® TCP Enable mem-
ber. NOTE: A reset is required for this change to take effect.

Modbus® TCP does not proxy requests and there is virtually no delay between request and response. A keep-alive fea-
ture is enabled on all accepted sockets to prevent leaks if a socket is not closed properly after an applicationcrash, loss
of link, severed network, half-close, etc.

The RMA PLUS implements the following Modbus® function codes:

l

3: Read Holding Registers

l

4: Read Input Registers

l

6: Write Single Register

l

16: Write Multiple Registers

Modbus® TCP supports all integer data types, floats, enums, and parameter types, but not strings.

The 16-bit word / register order of multi-register data types may be changed. By default, the word order is low, high.
