is created using all five IEC 61131-3 programing languages:
- IL;
- FBD;
- LD;
- ST;
- SFC.
Function block is a counter with reset control input.
If reset is True counter value is reset to the value defined by
global configuration constant ResetCounterValue.
If reset is False, counter is incremented every cycle.
