Method for Checking Errors

The errors for the I/O module can be classified into the following three categories. The checking methods for each error are as
follows.
Classification
I/O module specific error
CC-Link IE Field Network Basic related error
SLMP communication related error
When multiple I/O module specific errors have occurred, the error codes are stored in the following priority.
• When the error type differs, they are stored in the order of major error > moderate error > minor error.
• When the error status is the same, they are stored in reverse chronological order.
Method for clearing an error
■Method for clearing I/O module specific error
The method for clearing an error depends on the error type.
Error type
Major error
Moderate error
Minor error
■Method for clearing CC-Link IE Field Network Basic related error
After eliminating the error cause of I/O module, clear the error on the CC-Link IE Field Network Basic diagnostic window. For
how to use the CC-Link IE Field Network Basic diagnostics, refer to the following.
 CC-Link IE Field Network Basic Reference Manual
■Method for clearing SLMP communication related error
When the I/O module detects an SLMP command error, error status does not occur in the I/O module. Thus, error clear is not
needed.
