Technical term Description
Master See >Fieldbus master
MDT
Mobile Data Tag
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.
RPDO Receive Process Data Object: event-oriented CANopen communi-
cation service that transmits data from the bus master to the SLK.
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.
Slave See >Fieldbus slave
SLK
Schreib-Lese-Kopf
Fieldbus slave with HF communication unit for non-stationary, no-
contact communication between user controller and MDT.
SLK address Required to read and write data via the fieldbus.
Syslog buffer Buffer for recording system internal events.
Toggle bit Bit for controlling command-oriented data exchange.
TPDO Transmit Process Data Object: event-oriented CANopen communi-
cation service that transmits data from the SLK to the bus master.
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
browser. Contains the network address for the SLK.
