I am using Weintek MT8100i HMI and Schneider Modicon M340 PLC. In easybuilder file, I have Defined the PLC as Schneider Modbus TCP/IP type. Now when I connect PLC to Weintek HMI using ethernet crossover cable, neither the PLC is detecting the HMI nor is HMI getting any response from PLC. Has anybody ever encountered this type of problem before because I am doing just as weintek manual and PLC connection guide says still there is no communication between PLC & HMI.
