• The I/O module status is different from the I/O module
information at power ON.
• The I/O module (or intelligent function module) is nearly
removed, completely removed, or mounted during running.
■Collateral information
• Common Information (SD5 to SD15): Network No./Station
No.
• Individual Information (SD16 to SD26): -
■Diagnostic Timing
• Always
• Read common information of the error using GX
Works2 or GX Developer to identify the numeric
value (module No.). Check the module
corresponding to the value and replace it as
necessary.
• Monitor the special register SD1400 to SD1431 using
GX Works2 or GX Developer to identify the module
whose data bit is "1". Then check the module and
replace it as necessary.
