Address
The following programming can be used with the flags in A023 to detect when
the system switches from duplex to simplex operation.
If the contents of A023 is not 0, the “duplex error” output is turned ON to indi-
cate that the system has switched to simplex operation.

#0
ON: A duplex verification error caused a switch from duplex
to simplex operation. Only operation is switched and the
active CPU Unit will not be switched.
This flag is turned OFF when duplex operation is restored.
ON: A duplex bus error caused a switch from duplex to sim-
plex operation. Only operation is switched and the active
CPU Unit will not be switched.
This flag is turned OFF when duplex operation is restored.
ON: An error during duplex initialization caused a switch
from duplex to simplex operation and duplex operation was
never started. The active CPU Unit will not be switched.
This flag is turned OFF when duplex operation is restored.
ON: Changing the CPU Unit’s switch from USE to NO USE
caused a switch from duplex to simplex operation. The
active CPU Unit will be switched.
This flag is turned OFF when duplex operation is restored.
ON: A CPU Unit error (WDT) caused a switch from duplex to
simplex operation. The active CPU Unit will be switched.
This flag is turned OFF when duplex operation is restored.
ON: Execution of an FALS instruction caused a switch from
duplex to simplex operation. The active CPU Unit will be
switched.
This flag is turned OFF when duplex operation is restored.
ON: Exceeding the cycle time caused a switch from duplex
to simplex operation. The active CPU Unit will be switched.
This flag is turned OFF when duplex operation is restored.
ON: A program error caused a switch from duplex to simplex
operation.The active CPU Unit will be switched.
This flag is turned OFF when duplex operation is restored.
ON: A fatal Inner Board error caused a switch from duplex to
simplex operation. The active CPU Unit will be switched.
This flag is turned OFF when duplex operation is restored.
ON: A memory error caused a switch from duplex to simplex
operation. The active CPU Unit will be switched.
This flag is turned OFF when duplex operation is restored.
