Note
Usage of this example program
This example program was created on a powerful Beckhoff C6920 Industrial PC and re-
quires high computing power.
While testing this program, the following factors should be considered:
• In all tasks, the exceeding counters should not increment and an even utilization should be displayed.
• If an uneven execution of the PLC program is unavoidable, the activation of IoAtTaskBegin should be
considered
• You should decrease the buffer size, if necessary, advice regarding this is given below
• If the EL3773 indicates sync errors in the ADS logger window
or in the DiagMessages,
