FB_ReadTaskExceedCounter
The function block reads the Exceed Counter. The Exceed Counter is incremented by the system whenever the selected task exceeds the set task time. This means that the real-time could not be maintained in the cycle.
The reasons for exceeding the real-time can be very diverse, but usually it is due to the PLC runtime and the application within this runtime. An example of this are programming loops such as FOR, WHILE, REPEAT, since these are always processed in one cycle.
