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(5)_Compare is set to TRUE.
• If there is a FALSE-TRUE edge is at the input bCountIn1(5)_ResetCompare, the output
bCountIn1(5)_Compare can be reset to FALSE.
• If there is a FALSE-TRUE edge at the input bCountIn1(5)_LoadStartValue, the current counter
content can be reset to the parameterised starting value.
