12.3.11 Error codes returned to request source during communication with CPU module

POINT
This error code is not an error that is detected by the CPU module self-diagnosis
function, so it is not stored in the special relay (SD0).
When the request source is a GX Developer, a message or an error code is
displayed.
When the request source is an intelligent function module or network system, an
error is returned to the process that was requested.
