2 Designations and Abbreviations
2.1 Profibus DP-Specific
PNO Profibus user organisation [“Profibus-Nutzerorganisation”]
DP Profibus decentralised periphery
ID Identifier
GSD
Device master file – An electronic data sheet is a template provided by the
manufacturer, which stipulates how to present information and which matching
entries can be made.
DPM1
DP Master Class 1 – Central control which, in a set message cycle, exchanges
information with the decentralised stations (DP slaves). Typical devices are e.g.
programmable logic controllers (PLCs), PC systems or VME systems.
DPM2
DP Master Class 2 – Programming, projection or operating devices. They are
used during commissioning, to produce the configuration of the DP system or to
operate the running system.
Node
A node is a hardware unit with a unique address in the network (also known as
device).
MAC ID Address of a Profibus node (Medium Access Control).
SAP Service Access Point – in Profibus layer 2
FDL Fieldbus Data Link – Profibus data link layer 2.
DDLM
Direct Data Link Mapper – the interface between basic DP functions and the
user interface (also known as profiles).
IO (I/O) Input and output data.
Input data
This data is produced by a Profibus device (slave device) and collected by a
master device and made available for reading by the processor of the PLC.
Output data
This data is produced by a PLC processor and written to the memory of the
master device. The master device sends this data to other Profibus devices
(slave devices).
