Module 9262 Context change between spawn processes
You can call Module 9262 only in a submit job or spawn job. The module
switches the context to another PLC process or submit queue if such a
process exists and is not waiting for an event or for the expiration of a dwell
time. Markers 4200 to 4202 and 4204 have undefined changes after the
module call.
Call:
CM 9262

Module 9263 Interrupting a spawn process for a defined time
You can call Module 9263 only in a submit job or spawn job. The module
interrupts the calling process for at least the specified time. If other processes
or the submit queue are ready to run, the TNC changes the context to one of
these processes. Markers 4200 to 4202 and 4204 have undefined changes
after the module call. The waiting period is interpreted as an unsigned number,
so that negative values result in very long waiting periods.
Call:
PS B/W/D/K <Waiting period in ms>
