I set up a Modbus card to communicate with an analyzer . But when trying to simulate the words communication using a Modbus simulator could not establish communication between the simulator and my AC800M .
My MB Conecct block is not valid. The LEDs of the Modbus card flash tx and Rx when sending data from the simulator , however not get the values in the AC 800M .
Could someone help me with a simple configuration so that I can test this link ?
With your brief description we can only predict some point about the communication problem.
For Serial Modbus and Modbus TCP communication, there are some documents exist on the AKS. Please see below links for these documents:
Could you please check your configuration once again, according to these documents.
Hope it helps you.
