APPENDIX 1 Error Code Return to Origin During General Data Processing
The CPU module returns an error code to the general data processing request origin
when an error occurs and there is a general data processing request form the
peripheral equipment, intelligent function module, or network system. If an error occurs
when a general data processing is requested from the peripheral devices, intelligent
function module, and network system.
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 origin is a GX Developer, a message or an error code is
displayed.
When the request origin is an intelligent function module or network system, an
error is returned to the process that was requested.
