Function
A function calculates a result according to the current value of its inputs.
A function has no internal data and is not linked to declared instances. - Sets the reference position Position means a point in space which is described by different coordinates.
Depending on the used system and transformation it can consist of a maximum of six dimensions (coordinates).This means three Cartesian coordinates in space and coordinates for the orientation.
In ACS there can be even more than six coordinates.
If the same position is described in different coordinate systems the values of the coordinates are different. of a comparator block.

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 New start of the microprocessor..
- 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.
