Counter 1 – 12 (40023, 40024 – 40045, 40046)
The modules have 32-bit counters, one for each Digital Input.
In the register with lower number is stored lower byte of the counter and in the register with
higher number is stored higher byte of the counter.
In the case you would like to change the value of the register you can write any value (called
preset) for pulse counting registers. In the particular case, you can reset the counter by
entering 0. Reset counter is also possible via the registry 40022.
