Hi Guys,

Can ControlLogix with Modsim32 for Modbus Server Testing?

I have ControlLogix via Anybus Modbus TCP and I need to Test the configuration.

Any ideas will be appreciated.
 
I tried it, I was able to write from controllogix to Modbus Server Simulator only twice and it never worked again even with restarts/reconnection of the Demo
 
I alternate modsim with the modRSsim2 here, it is free:
https://sourceforge.net/projects/modrssim2/


I like modRSsim when I just need a quick set of registers, it takes less time to configure. I have found that in Serial situations, where a person might want to have a mix of Real nodes and a simulated node, this simulator will not play nice. It really wants to be the only serial node on a chain/line.
TCP works fine.
