Configuring the Distributed I/O (DP)
STEP 7 V5.3
This version of STEP 7 can interpret GSD files up to GSD Revision 5. This means
that you can use new functions also for DP slaves that are installed using GSD
(Revision 5):
• Using a DP Slaver as a receiver (subscriber) for direct data exchange (lateral
communication).
• Redundant configuration of a DP slave in an H station.
A DP slave can be redundantly configured if the GSD entry
"Slave_Redundancy_supp = 8" is present.
• Clock Synchronization for DP slaves.
A DP slave with the GSD entry "Time_Sync_supp = 1" provides the "Clock
Synchronization" tab for configuring this function.
STEP 7 V5.3 Service Pack 1
In addition to GSD files for DP slaves (up to Revision 5), this version of STEP 7
can also interpret GSD files for PROFINET IO devices in XML format (Generic
Station Description). Both types of GSD files are handled identically.
There are special considerations with respect to naming these new GSD files and
specifying their versions. STEP 7 V5.3, Service Pack 1, interprets GSD files with
the GSDML schema V1.0.
