Function
The time of the previous switch from
duplex to simplex operation is stored.
Seconds (00 to 59)
Minutes (00 to 59)
Hours (00 to 23)
Day of month (01 to 31)
Month (01 to 12)
Year (00 to 99)
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 oper-
ation is restored.
ON: A duplex bus 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 oper-
ation 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 oper-
ation 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 oper-
ation 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 oper-
ation 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 oper-
ation is restored.
