The task time is set in PLC Control. The default setting is 20ms.
Fig.47: Setting the task time
In the default setting, the PLC program is called every 20ms, as long as the general cycle time is less than
20ms. To determine the load of your system, the PLC cycle time can be measured in the System Manager.
In order to ensure trouble-free operation, the set task time should be 20-30% higher than the measured total
cycle time. A precise cycle time breakdown can be found under K-Bus tab [}46] description. The total cycle
time is displayed with the TcBase library (see TcBase.lbx or TcBaseBCxx50.lbx).
