I am starting a system and cannot make 3 plcs communicating through CIP messaging. Specifically i am using CIPUCMMWrite instruction to send a simple structure (array of 48 booleans) to each of two plc, they will also reply in the same exact way with another array of 48 booleans. The istruction will fail with codes: ErrorID: 1C00 ErrorIDex: 20008022 and the extended code is undocumented in the literature i have with me. So far i changed cpu units and redone ethernet wiring, to no avail. What meaning have the code 20008022? and what can be possible checked to make sure the communication is taking place?
