Input PV of a Counter

To this value the counter will be set if a rising edge is detected at the S-input. This input will not have to be connected if you do not need this function. But the pure down-counter is quite useless with an unconnected S- or ZW-input. The value that is fed into this input has to be BCD coded. The easiest way to do this is to write it as C# constant. Naturally, here can also be any word variable. The counter can only be set to values from 0 up to 999.
