Grounding
Grounding means connecting a conductive part to ground via a grounding system.
Grounding conductor PA
Term for electrical equipment used in the hazardous area to which the
equipotential bonding is connected.
GSD file
A GSD file (device database file) contains all the properties specific to a DP slave.
The format of the GSD file is specified in the standard IEC 61158/EN 50170,
Volume 2, PROFIBUS.
HART
Highway Adressable Remote Transducer
Hot swapping
Removing and inserting modules while the ET 200iS is operational.
Identification data
The identification data allow you to read out module information (vendor, type,
product version etc.) using SIMATIC PDM. The module information is resident in
the module memory.
Line compensation
Resistance and RTD measurements with 2/3-wire connection without measuring
circuits result in additional measuring inaccuracies. These are compensated by line
compensation.
Master
When a master is in possession of the token, it can send data to other nodes and
request data from other nodes (= active node). The DP master can, for example,
be the master interface module IM 308 C or the CPU 315-2 DP.
Node
Device that sends, receives, or amplifies data over the network, for example, DP
master, DP slave, RS-485 repeater.
