“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.

SLK preparation

An unbuffered prefetch is configured that transmits both the MDT status (see
Chapter 4.3.2.1 “MDT status register”) and the control data (e.g., 16 bytes as of
MDT address 0x0024) in the event-oriented data channel. The SLK switches to auto
disconnect mode and the link state switches to

CONNECTING

.

No.

Wait until event counter in event-oriented data channel (see Chapter 7.3.1 “Status informa-
tion in event-oriented data channel”) to increase by 1. At this point, a workpiece pallet has
arrived, the event-oriented data is valid and the link is

DISCONNECTED

. The MDT status and

control data can be checked and the workpiece pallet can be raised.
