Unistream, Read Modbus from 3rd party PLC

Recommended Posts

I have a Schneider M340. I am just new to Unilogic programming. The documentation seems to indicate that I can just setup the communication section with a remote slave under the Modbus Master section and add some operations to read addresses and it should work. Am I missing something. Do I need ladder code as well or can I just use the periodic reads in the communications section.
