  1. GE Fanuc 90-30 communication module?

    I need to connect 4 PLC’s models 90-30 with the following CPU: Rack 1 CPU 332 Rack 2 CPU 340 Rack 3 CPU 331 Rack 4 CPU 363 The project requires a PC HMI reading all the variable registers inside the PLC’s. I have at least one empty slot in each PLC. Could someone please recommend a communication module to place on each of the PLC? I need you help with the following issues: Which communication part number Modules and Cables to buy for each PLC? Which PLC do you recommend as the Master? Thanks for all your answers. Andy
