Description
See >Fieldbus master
Electronic memory. The MDT is fixed to the workpiece pallet and
contains the current information on the workpieces on the work-
piece pallet.
Located in the first segment of the SLK address area.
Fills an MDT memory area with a constant formatting value
32-bit number that has a different value in each MDT and cannot
be edited. This allows every MDT to be uniquely identified.
Information on MDT type and current MDT state.
3-bit coding of the MDT type contained in the MDT status. The
MDT type code provides information on the MDT memory capacity.
Pretransmit executed for all MDTs.
IP address, part of the web address.
Emergency shell
Abbreviation for the Profibus DP fieldbus system that supports
cyclical data communication in accordance with EN 50170.
Automatic read access to the MDT. Prefetch has to be configured
in advance. Prefetch always occurs before the CONNECTED state.
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.
Serial interface for the SLK for parameterization and extended
diagnostics as per RS232 specification.
Receive Process Data Object: event-oriented CANopen communi-
cation service that transmits data from the bus master to the SLK.
Division of the SLK memory area into individual segments that are
64 kB in size.
Command line-based input option via the serial interface using a
terminal program or ID 40/KONF.
Pretransmit only executed on the next MDT.
See >Fieldbus slave
Fieldbus slave with HF communication unit for non-stationary, no-
contact communication between user controller and MDT.
Required to read and write data via the fieldbus.
Buffer for recording system internal events.
Bit for controlling command-oriented data exchange.
Transmit Process Data Object: event-oriented CANopen communi-
cation service that transmits data from the SLK to the bus master.
Time in which the MDT is in the SLK transmission area.
Internet browser or simply "browser", interactive program for
displaying websites.
Functional component in the ID 40/SLK, contains the ID 40/SLK
website.
The entire online presence of the SLK.
URL, Uniform Resource Locator. Addresses the SLK website in the
browser. Contains the network address for the SLK.
