SLK operation
Check the actual link state until the value
CONNECTED
appears (2). A new MDT has
now arrived. The controller reads the MDT status (4). When the MDT status does not
indicate an error, the user data can now be read starting with MDT address 0x0110.
Once this data has been evaluated and the workpiece processed, the result of
the processing is written to the MDT (6). Communication with the MDT is then
terminated.
