Modbus traffic on 1200R

Maarten_Sjouw — Wed, 05 Feb 2020 06:03:37 GMT

Hi, I got a question from a customer:

Is it possible to filter modbus traffic and would this also work in transparent mode?

Does anyone have experience running this?

AppWiki reports that Gateways support granular visibility and control of ~25 Modbus commands.

Modbus is also specifically documented on the 1200R datasheet.

Sure that should work without any issues

Maarten,

we had a customer filtering this but not in transparent mode.

No problems known with this.
