• 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

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.
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 Timer for the paused step will continue to
operate even while the step is paused.
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 Timer for the paused step will continue to operate even
while the step is paused.
Restarts execution of an SFC task that was ended or paused using one of the other SFC Task Control Instructions.
