“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.
