ControlLogix with Modsim32 for Modbus Server Testing

[Chibu]

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.

Give QModMaster a try:

https://sourceforge.net/projects/qmodmaster/

its free, its open source, and it works, just used it last friday to do just that (but with a Siemens PLC)!

I'm looking for the Modbus Slave simulator

The Modbus Tools's Modbus Slave is not free of charge but it is not too expensive either. I have used it for years.

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

Yees, the demo version has some limitations. I used the licensed version, It is not open source.

I alternate modsim with the modRSsim2 here, it is free:

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.
