Measuring the PLC Cycle Time
The task time is set in PLC Control. The default setting is 20 ms.
In the default setting, the PLC program is called every 20 ms, as long as the general cycle time is less than 20 ms.
The cycle time can be measured in the System Manager in order to determine your system load. To ensure trouble-
free operation, the set task time should be 20 to 30 % higher than the measured cycle time. A precise cycle time
breakdown can be found under K-Bus tab description.
