General functionality

Brief description
To make measurements at real machines, probes must be connected which supply switching
signals at certain positions. Probes are not used when making measurements in simulated
environments - the switching positions are specified in a different way.
Simulated measuring supports two ways of entering switching positions:
● Position-related switch request: The switching position is derived from the axial end position
programmed in the measuring block.
● External switching request: The switching position is defined by controlling a digital output.
