SFC Task Control Instruction Specifications
The following type of control can be achieved by using the SFC Task Control Instructions
•
Ending SFC task execution using the SFCOFF instruction
•
Pausing SFC task execution and resetting outputs using the SFCPR instruction
•
Pausing SFC task execution and holding outputs using the SFCPRN instruction
•
Restarting execution of SFC tasks that have been ended or paused using the SFCON
instruction
SFC OFF: SFCOFF
Ends execution of an SFC task. The outputs from any actions that are being
executed in the task that is ended will be held and processing will be ended.
When execution is started again with the SFCON instruction, it will start from the
initial step.
SFC PAUSE WITH
RESET: SFCPR
All outputs in the task that is paused will be reset and processing will be paused.
Be careful when using this command if any outputs that will be reset are used in
other tasks.
When execution is started again with the SFCON instruction, it will start from the
step that was active before the task was paused.
The Step Time for the paused step will continue to operate even while the step is
paused.
SFC PAUSE WITH NO
RESET: SFCPRN
Pauses execution of an SFC task. The outputs from any actions that are being
executed in the task that is paused will be held and processing will be paused.
When execution is started again with the SFCON instruction, it will start from the
step that was active before the task was paused.
The Step Time for the paused step will continue to operate even while the step is
paused.
SFC ON: SFCON
Restarts execution of an SFC task that was ended or paused using one of the other
SFC Task Control Instructions.
