Good morning all,
I have many robot cell controllers here where a fanuc robot loads and unloads a part through various machines, then drops them out on an exit conveyor. All of the machines in the cell already have its own PLC, but they are all tied to a Main PLC / Cell controller PLC, which controls when each machine will cycle, making sure the robot is out of way, part present, fixture unclamped, etc etc.
This seems common in my facility, unsure about yours. Why have a separate cell controller, when this can be tied to the fanuc robot controller (for example R30iA or R30iB?). So instead of machines receiving signals from cell controller plc, why not just receive directly from robot?
I feel the master plc is unnecessary? What's the reason behind having a master plc controller in these cells?
Thanks,
