10-7-5 Turning OFF Outputs

Turn ON the Output OFF Bit (A500.15) to turn OFF the outputs of all Output Units regardless of the sta-
tus of the output bits in I/O memory. This can be used for urgent error processing when the Unit is oper-
ating in RUN or MONITOR mode. The INH indicator on the front of the CPU Unit will light yellow.
The status of the Output OFF Bit is maintained even if power is turned OFF and ON if there is a battery.

Additional Information
By default (i.e., if the IOM Hold Bit (A500.12) is turned OFF), all the outputs will be cleared (i.e.,
turned OFF) if the operating mode is switched from RUN or MONITOR mode to PROGRAM
mode. If an output bit in I/O memory is turned ON by the user program, the output will turn ON
when I/O is refreshed. To turn OFF all outputs from the Output Units regardless of the operating
mode, use the Output OFF Bit.
