Mounting instructions
The DP/P-bus link must be installed horizontally as shown in the diagram, to ensure
that heat is dissipated.
Rail mounting
The housing base is designed for snap-
mounting on a DIN rail, type EN50022-
35x7.5 (access with a screwdriver)
Surface mounting
There are four drill holes for screw
mounting (see “Dimensions” for drilling
diagram). The housing base is fitted
with raised supports.
Screws: max. 3.5 mm
When mounting note the following:
• There must be a means of dissipating the heat generated during operation.
• Easy access is required for service personnel
• Local installation regulations must be observed.
The mounting instructions are printed on the packaging.
Engineering notes
The master device file (GSD file), which defines the technical characteristic of a
Profibus DP link, is used as the basis for project engineering.
As part of the engineering process, the engineering tool (SIMATIC Manager) needs
information about which GSD file to use for the DP/P-bus link. This is normally
achieved by copying the GSD files to the hard disk of the PC. (For the exact path
details refer to the description of the engineering tool.) When engineering a plant, the
project engineering tool interprets the data in the GSD file for the DP/P-bus link.
It also runs plausibility checks to ensure that the engineering data is correctly structured
in terms of logic. At the end of the engineering process, the user can transfer the
collated engineering data to the master (SIMATIC S7). At system start-up, the master
transmits this engineering data to the DP/P-bus link. Apart from addressing, no other
settings are required for the DP/P-bus link.
