"Workstation" application

This example is for a workstation with a lift positioning unit. Since a link cannot be
established between the SLK and the MDT when the workpiece pallet is raised, data
is exchanged in two stages.
Stage 1: Reading the workpiece-specific data to check whether or not this workpiece
can be processed at this station. The data is read from the MDT in an event-oriented
manner. The SLK then automatically switches to DISCONNECTED. Only when the lift
positioning device lowers after processing does the SLK switch to CONNECTING.
This eliminates the risk of an unexpected break in communication as the MDT
approaches the SLK from above.
Stage 2: Entering measurement data obtained while the workpiece was being
processed. Only the pretransmit function is used here.
