Grounding
Grounding means connecting an electrically conductive part to a grounding
electrode by means of a grounding system.
Grouping
The opening of a new potential group by a power module. This permits the
individual grouping of the sensor and load supplies.
GSD file
The properties of a PROFINET device are described in a GSD file (General Station
Description), which contains all information required for configuration.
Just as with PROFIBUS, you can integrate a PROFINET device in STEP 7 with a
GSD file.
In PROFINET I/O the GSD file is in XM format. The structure of the GSD file
complies with ISO 15734, the world standard for device descriptions.
In PROFIBUS the GSD file in in ASCII format (compliant with IEC 61784-1:2002
Ed1 CP 3/1).
Hot Swapping
This is the removal and insertion of modules during the operation of the ET 200S.
Isolated
In the case of isolated input/output modules, the reference potentials of the control
and load circuit are galvanically isolated -- for example, by means of optical
isolators, relays, or transformers. Input/output circuits can be grouped.
MAC address
A unique device identification is assigned to every PROFINET device at the
factory. The 6-byte-long device identification is the MAC address.
The MA address is divided into:
•
3 bytes manufacturer ID and
•
3 bytes device ID (sequential number).
The MAC address is generally placed on the front of the device for easy access.
For Example. : 08–00–06–6B–80–C0
Master
When it has a token, a master can send data to and request data from other nodes
(= active participants). Examples of DP masters are the CPU 315-2 DP or the
IM308-C.
