Program operator request. Set to true by the user
program to request Operator control. Holding this true
locks the instruction into Operator control.
Default is false.
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.
Program hand request. Set to true by the user program to
request the device to enter Hand mode.
Default is false.
Operator program request. Set to true by the operator
interface to request Program control. The instruction
clears this input to false.
Default is false.
Operator operator request. Set to true by the operator
interface to request Operator control. The instruction
clears this input to false.
Default is false.
Reset program control values. When true, all the program
request inputs are cleared to false at each execution of the
instruction.
Default is false.
Description
Indicates if instruction is enabled.
The output of the 2-state instruction.
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.
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.
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.
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.
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.
Program/Operator control indicator. True when in
Program control. False when in Operator control.
Override mode. True when the device is in the Override
mode.
