SUSPEND - Suspend Program or Task

The Suspend Program or Task (SUSPEND) instruction is used to programmatically stop the designated Program or Task from running.

When this instruction has power flow the designated Program or Task will not run. The current state of all of the ladder logic in the Program or Task will be maintained. When this instruction loses power flow the designated Program or Task will resume running from the point it was suspended.

When a Program or Task that is suspended, its .InstrSuspend structure member will be ON and the name of that Program or Task will be shown with a  yellow  background in the Project Browser.

Note: a Program or Task cannot contain a SUSPEND instruction that targets itself, that is, a Program or Task can NOT suspend itself.
