Tab ‘Monitor’

Object: Task Configuration

This tab shows the following information in online mode: status for tasks in the task configuration and some current measurements of the cycles and cycle times. CODESYS updates the values in the same time interval as for the monitoring of values from the PLC.

Reset the displayed values 0 by right-clicking the task and then clicking the Reset command in the context menu.

Task	Task name (as defined in the task configuration)
Status	Not generated: The task has not been started since the last update (especially for event tasks). Generated: The task is recognized in the runtime system, but not yet in operation. Valid: The task is operating normally. Exception: The task has produced an exception status.
IEC Cycle Count	Number of cycles executed since starting the application where the IEC code was executed (0 if the target system does not support the counter function)
Cycle Count	Number of executed cycles since logging in to the PLC. It depends on the target system whether cycles are also counted where the application is not running. In these cases, the Cycle Count may be greater than the IEC-Cycle Count.
Last Cycle Time (µs)	Last measured cycle time (in µs)
Average Cycle Time (µs)	Average cycle time over all cycles (in µs)
Max. Cycle Time (µs)	Maximum measured cycle time over all cycles (in µs)
Min. Cycle Time (µs)	Minimum measured cycle time over all cycles (in µs)
Jitter (µs)	Last measured jitter (in µs) Jitter is the difference between the time when the task should be started and the time when the task is actually started. For example, if the task should be started every 1000 µs and it actually starts after 1100 µs, then the jitter is 100 µs.
Min. Jitter (µs)	Minimum measured jitter (in µs)
Max. Jitter (µs)	Maximum measured jitter (in µs)
