Requirements
In order to use fail-safe DP standard slaves with S7 Distributed Safety, the standard slaves
must be on the PROFIBUS-DP and support the PROFIsafe bus profile. Fail-safe DP
standard slaves that are used in a mixed configurations on PROFIBUS DP and PROFINET
IO after IE/PB links, must support the PROFIsafe bus profile in the V2 mode.
In order to use fail-safe standard I/O devices with S7 Distributed Safety, the standard
devices must be on the PROFINET IO and support the PROFIsafe bus profile in V2 mode.
Configuration with GSD/GSDML Files
As is the case in a standard system, the basis for configuring fail-safe DP standard
slaves/standard I/O devices is the specification of the device in the GSD/GSDML file
(Generic Station Description/Generic Station Description Markup Language).
All the properties of a DP standard slave are saved in a GSD file. Standard I/O device
properties are saved in the GSDML file. For fail-safe DP standard slaves/standard I/O
devices, portions of the specification are ensured by a CRC.
GSD and GSDML files are supplied by the device manufacturers. The user imports the
GSD/GSDML files into his project (see
slave / IO standard devices imported, it can be selected from the hardware catalog of
