ProgOperReq BOOL Program operator request. Set to true by the user
program to request Operator control. Holding this true
locks the instruction into Operator control.

ProgOverrideReq BOOL Program override request. Set to true by the user program
to request the device to enter Override mode. Ignored if
ProgHandReq is true.
Default is false.
ProgHandReq BOOL Program hand request. Set to true by the user program to
request the device to enter Hand mode.
Default is false.
OperProgReq BOOL Operator program request. Set to true by the operator

Default is false.
Output Parameter Data Type Description
EnableOut BOOL Indicates if instruction is enabled.
Out BOOL The output of the 2-state instruction.
Device0State BOOL Device 0 state output. Set to true when the device is
commanded to the 0 state and the feedbacks indicate the
device really is in the 0 state.
Device1State BOOL Device 1 state output. Set to true when the device is
commanded to the 1 state and the feedbacks indicate the
device really is in the 1 state.
CommandStatus BOOL Command status output. Set to true when the device is
being commanded to the 1 state and cleared when the
device is being commanded to the 0 state.
FaultAlarm BOOL Fault alarm output. Set to true if the device was
commanded to a new state and the FaultTime has expired
without the feedbacks indicating that the new state has
actually been reached. Also set to true if, after reaching a
commanded state, the feedbacks suddenly indicate that
the device is no longer in the commanded state.
ModeAlarm BOOL Mode alarm output. Set to true if the device is in Operator
control and a program command changes to a state which
is different from the state currently commanded by the
operator. This alarm is intended as a reminder that a
device was left in Operator control.
ProgOper BOOL Program/Operator control indicator. True when in
Program control. False when in Operator control.
Override BOOL Override mode. True when the device is in the Override
mode.
