Setting Up the Counter
To start a counting process at least the signal mode needs to be parameterized and a rising
edge at the bit QX8.2 (“Set SW gate”) of the control word is required.
You can define the counter functions by parameterizing: the counting mode, a primary
direction (counting up or down), the counting behavior, and the hardware gate function
(input gate). In addition, you can parameterize output setting options (comparison
function, hysteresis) as well as producing a process alarm (refer to Section 5.16.10,
