Example for a Battery Error
Note Use the same methods as for actual system errors to clear the simulated sys-
tem errors. Refer to the 9-2 Troubleshooting for details. All system errors sim-
ulated with FAL(006) and FALS(007) can be cleared by cycling the power
supply.

Output OFF Bit
As an emergency measure when an error occurs, all outputs from Output
Units can be turned OFF by turning ON the Output OFF Bit (A500.15). The
operating mode will remain in RUN or MONITOR mode, but all outputs will be
turned OFF.
Note Normally (when IOM Hold Bit = OFF), all outputs from Output Units are turned
OFF when the operating mode is changed from RUN/MONITOR mode to
PROGRAM mode. The Output OFF Bit can be used to turn OFF all outputs
without switching to PROGRAM mode.
Application Precaution for
DeviceNet
When the CPM1A-DRT21 is used, all slave outputs will be turned OFF, i.e., all
inputs to the master will be OFF.
