Modbus to FOUNDATION fieldbus converter

T610 Modbus to FOUNDATION fieldbus converter

The T610 is a built-in module for interfacing Modbus RTU transmitters to a FOUNDATION fieldbus network(FF).

T610 includes a Modbus master in order to communicate with a Modbus instrument. The module reads the variables from the instrument and converts this to a dynamic variable on FF. Four AI Function Blocks are supported. The location of the Modbus registers and data type of the Modbus variable can be configured from any FF configurator. The T610 is tested against ITK 5.2.0 Other Function blocks can be added on request. The device has LAS (Master functionality).


The T610 is intended for Modbus RTU instruments that shall be upgraded to interface to FOUNDATION fieldbus

The following power options are available for powering and galvanic isolation:

The T610 comes with Galvanic isolation for instruments that are separately powered
Power supply for the instrument (3.3Vdc).
Option 2 is only possible for low power consuming devices. The electrical interface should be CMOS.

The following physical interfaces are supported:

RS 232
RS 485
FF functionality supported:

Low pass filtering
Unit conversion
User calibration
Diagnostic information
Before starting to use the T610, it is recommended to purchase the Starter kit, ST61. It contains all the necessary tools for configuration and evaluation of the FF technology.
