12.3.11 Error codes returned to request source during communication with
CPU module
The Q series CPU module returns an error code to the request source if an error occurs at
a request of communication from GX Developer, intelligent function module or 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 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.
The error contents of the error codes (4000H to 4FFFH) detected by the CPU module and
the messages displayed by the GX Developer are shown in Table12.12.
