Modbus simulation in machine expert

Hello,

 

I am newbie with shneider software, I am using machine expert v2.0 and I am trying to simulate my m241 project with modbus slave simulator even when I simulate 2 plcs M241 ( 2 projects) there is no data exchange via Modbus Tcp/ip.

Can you help me please? Shall I use Read_VAR or only generic modbus Tcp slave configuration ?

I haven't used the Machine Expert platform, but typically when running code in a Simulator, field communications (including Modbus) aren't operative.

 

You'd need to use real hardware to get the Modbus communications working (typically).

Thank you for your response. I know that serial communications need real HW but with tcp/ip communications we can simulate as you see in attachment I was able to do that with Control expert v15 and modbus poll.  ControlExpert.png

The online manual seems to refer to simulation here
