Good day all, i need advice for Modbus TCP configuration on mitsubishi iQ-R PLC. I have 4 PLC iQ-R R08P CPUs with the configuration as shown in the picture. PLC 1,2,3 communicate with the master PLC using simple CPU Read/Write communication. from the master PLC, all tags on PLC 1,2,3 are configured to be modbus TCP with the RJ71EN71 module. The problem I am facing is how do I get the communication status of each PLC to the master PLC with simple CPU communication. I want to display the communication results of each PLC as a tag on modbus TCP. Thank you very much
