GSD file
The properties of a PROFINET device are described in a GSD file (Generic Station
Description), which contains all required information for the configuration.
A PROFINET device can also be integrated into STEP 7 by means of a GSD file, in the
same way as PROFIBUS.
In the case of PROFINET IO, the GSD file is in XML format. The structure corresponds to
ISO 15734, the worldwide standard for device specifications.
For PROFIBUS, the GSD file is in ASCII format
(according to IEC 61784-1:2002 Ed1 CP 3/1).
Hot-swapping
The removal and insertion of modules while ET 200pro is in run.
IM
Interface module: The interface module interconnects ET 200pro with the DP master and
prepares the data for the electronic modules.
Industrial Ethernet
Industrial Ethernet (previously SINEC H1) is a technology that allows data to be transferred
fail-safely in an industrial environment.
Standard Ethernet components can be used since PROFINET is an open system. However,
we recommend setting up PROFINET as Industrial Ethernet.
Industrial Wireless LAN
In addition to data communication, Industrial Wireless LAN from SIMATIC NET with the
standard IEEE 802.11, offers a multitude of extensions (I-Features) that are of great benefit
to industrial users. IWLAN is particularly suited for complex industrial applications with
requirement for reliable radio communication, owing to:
● Automatic roaming if connection to Industrial Ethernet is interrupted (Rapid Roaming)
● Cost savings generated by using a single wireless network for secure operation of a
● Cost-effective connection to devices in remote, difficult-to-access environments
Internal lightning protection
Shielding of buildings, rooms or devices Corresponds with lightning protection zone 1, 2 or 3.
