Causal factors
Failure of I/O bus or I/O bus connecting equipment. (I/O bus check: once a scan)
Extended I/O modules are mounted more than the maximum number of modules mounted 8 modules.
Countermeasures
Replace the equipment. Remove all I/O modules once, mount one module at a time, and check for any
abnormal modules. Set the number of extended I/O modules to 8 or less.

different.
Countermeasures
If the sequence is intentionally changed, register the sequence. If it is unintentional, check the alignment
and re-align it to the normal alignment.
