Modbus IL_ModBusTCPClient connection problem

[Chirag03]

Hello ,

I am using ctrlx PLC 1.20.4 and works 1.20.2  . I  try to connect modbus communication via IL_ModbusTCPClient function block . In which  Enable is true but InOperation is not true. I am not able to communicate with specify address but, i can ping this address via command prompt. Previously it was working fine but, now it is not showing InOperation true . Please see  attached picture for your reference  and give me solution.

When you can't connect you should check the following:

• Is the Modbus server running
• Is the ip and port correct
• are there any firewall settings (or e.g. VPN connections), which blocks the connection

You said it was working. What did you change since it is not working anymore?

Good morning

See if these manuals on Modbus communication between XM and ctrlX Core is helpful.

We have even used this to pass states from the IOs in Ethercat to the XM
