MLCompReadRef
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. - Returns 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.
