How can a TAC Vista system communicate with a Profibus device?

Issue

How can a TAC Vista system communicate with a Profibus device?

Product Line

TAC Vista

Environment

TAC Vista system

3rd Party Profibus device

Cause

A site may have existing devices that communicate via the Profibus field bus protocol and these are to be kept and integrated into the TAC Vista system

Resolution

There is no standard way to do this, but one way would be to use a Modbus to Profibus converter. On one side of the converter a X913 can communicate via Modbus and on the other side the Profibus device would communicate with the converter via Profibus. The X913 can then be integrated into Vista if/as required.
