T
ag
Electronic memory. The MDT is fixed to the workpiece pallet and
contains the current information on the workpieces on the work-
piece pallet.
MDT address
Located in the first segment of the SLK address area.
MDT formatting
Fills an MDT memory area with a constant formatting value
MDT ID code
32-bit number that has a different value in each MDT and cannot
be edited. This allows every MDT to be uniquely identified.
MDT status
Information on MDT type and current MDT state.
MDT type code
3-bit coding of the MDT type contained in the MDT status. The
MDT type code provides information on the MDT memory capacity.
Multiple transmit
Pretransmit executed for all MDTs.
Network address
IP address, part of the web address.
Emergency console
Emergency shell
PDP
Abbreviation for the Profibus DP fieldbus system that supports
cyclical data communication in accordance with EN 50170.
Prefetch
Automatic read access to the MDT. Prefetch has to be configured
in advance. Prefetch always occurs before the
CONNECTED
state.
Pretransmit
Automatic write access to the MDT. Pretransmit data has to be
entered in the SLK in advance. Pretransmit occurs as soon as the
MDT is linked and always before prefetch.
RS232 interface
Serial interface for the SLK for parameterization and extended
diagnostics as per RS232 specification.

Segment
Division of the SLK memory area into individual segments that are
64 kB in size.
Shell
Command line-based input option via the serial interface using a
terminal program or ID 40/KONF.
Single transmit
Pretransmit only executed on the next MDT.

Dwell time
Time in which the MDT is in the SLK transmission area.
Web browser
Internet browser or simply “browser”, interactive program for
displaying websites.
Web server
Functional component in the ID 40/SLK, contains the ID 40/SLK
website.
Website
The entire online presence of the SLK.
Web address
URL, Uniform Resource Locator. Addresses the SLK website in the
