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 maintaining real-time in the cycle was not possible.

There can be many reasons for exceeding real-time, but it is usually due to the PLC runtime and the application within this runtime. An example of this is programming loops such as FOR, WHILE, REPEAT, since these are always processed in one cycle.
