I am novice in LabVIEW, and i need help in the configuration between LabVIEW and the PLC. My PLC is Omron CJ1M-CPU11-ETN21. I have DSC Module and i have OPC Server as well. I did create tags or even used shared variables to try to write to the output of the PLC, but it does not works. The configuration for the PLC ethernet had done, and i can control the PLC using CX-programmer through Ethernet module. May i know what are the problems?
