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 bCount1_Compare output is set to TRUE.
• If there is a FALSE/TRUE edge at the bCountIn1_ResetCompare input, the bCountIn1_Compare
output can be reset to FALSE.
• If there is a FALSE-TRUE edge at the input bCountIn1_LoadStartValue, the current counter
content can be reset to the parameterised starting value.
