Counting behaviour
The following temporal characteristic shows the counting process depending on the
signals of the interfaces described before:
[6-1] Transient characteristic of a quick counter block, sampling cycle = 1 ms
 The counter starts with the parameterised starting value.
 If the comparison value is reached or exceeded:
– The counter jumps back to its starting value.
– The output bCount1(6)_Compare is set to TRUE.
 If there is a FALSE-TRUE edge is at the input bCountIn1(6)_ResetCompare, the output 
bCountIn1(6)_Compare can be reset to FALSE.
 If there is a FALSE-TRUE edge at the input bCountIn1(6)_LoadStartValue, the current 
counter content can be reset to the parameterised starting value.
