error)
Turns ON when there is an error in the memory. FQM1 operation will
stop and the ERR indicators on the front of the Modules will light.
Module
A403 00 UM Error Flag Turns ON when there is an error in the user memory.
04 System Setup Error
Flag
Turns ON when there is an error in the System Setup in the Coordina-
tor Module or Motion Control Module.

Checksum Error Flag
Turns ON when there is an error in the DM Area data backed up in
flash memory in the Coordinator Module.
A404 14 Memory Not Held Flag Turns ON when corruption is found in the check performed after turn-
ing ON power in the areas backed up during power interruptions (DM
Area (Coordinator Module only) and Error Log Area).
