Process monitor In the PLC programming mode you can use the MONITOR and PROCESS
MONITOR soft keys to open a status screen in which the control displays all
parallel processes, including the process for the submit queue. In a time
interval, which can be set with the "+" and "–" soft keys, the control displays:
The name of the process (TASKNAME)
The current status of the process (STATE)
• Executable (SCHED)
• Running (RUN+)
• Waiting for event (EVWAIT)
• Waiting for time period (TMWAIT)
• AND-gating of the bits in the event mask (AND)
• OR-gating of the bits in the event mask (OR)
The event mask (EVMASK)
The PLC module letting the process wait (MOD)
How often the process has changed contexts in the last time interval
(SCHED).
How much CPU time the processor has used from the defined time interval
(CPU(ms)). The control also shows the distribution of CPU time in a bar chart
(RATIO).
Module 9260 Receive events and wait for events
Call the module only in a submit job or spawn job. The module enables a
spawn job or submit job to interrogate or wait for the occurrence of one or
more events. At the same time, the module triggers a change in context.
If you transfer the value zero for the event mask, the control returns all set
events without deleting them. Otherwise, in a call with a waiting period, the
control returns all the requested events and deletes them. For a call without a
waiting period, the control returns and deletes the events only if the condition
is met.
If the events are OR-gated, the control returns and deletes only the set events.
You can specify the events to be deleted by calling without a waiting period
and with an OR gate.
