Error Messages¶
Note
If a function block returns an “invalid” (i.e. internal) error code which is not listed here, check for a possible version mismatch between PLC firmware and the CAA File Libraries. If the function block is supported definitely by the firmware version in the PLC, the IEC application might have too many active function blocks in parallel (maximum number is 20).
