22.3 Error Code List
When an error occurs at PLC power ON, on switching to the RUN status, or during the
RUN status, the self-diagnostics function displays the error content (by LED indication, or
message display on an LED indicator), and stores the error information at a special relay
(SM) and special register (SD).
If an error occurs on a data communicaton request from peripheral devices, a special
function module and the network system to the CPU module, error codes (4000H to
4FFFH) are returned to the request source.
QnACPU errors and corrective actions are described in this section.
