Remarks
- The Transition Flag of a comparator object turns TRUE if the input position to the comparator is greater or equal to the reference.
- The Comparator Transition Flag stays TRUE until it is reset.
- If the input ThroughZero is set to TRUE, system must cross zero and then the reference position before the Transition Flag is set.
- If ThroughZero is FALSE, Transition Flag is set immediately if the input pipe position is greater then or equal to the Reference value.
