Monitor/Modify, Programming Via Profibus; Power-Up Of The Dp Master System; Profibus Address Of The Dp Master; From En 50170 To Dpv1 - Siemens SIMATIC S7-400H Manual

Note
Is one of the PROFIBUS DP slaves a CPU 31x or a CPU 41x?
If it is, you will find it in the PROFIBUS DP catalog as a preconfigured station.
Assign this DP slave CPU a slave diagnostics address in the DP master. You must
link the DP master to the DP slave CPU and specify the address areas for the
transfer of data to the DP slave CPU.

Monitor/Modify, Programming via PROFIBUS

As an alternative to the MPI interface, you can use the PROFIBUS DP interface to
program the CPU or execute the Monitor/Modify programming device functions via
the PROFIBUS DP interface.
Note
The Programming and Monitor/Modify applications via the PROFIBUS DP
interface extend the DP cycle.

Power-Up of the DP Master System

Use the following parameters to set power-up monitoring of the DP master:
• Transfer of the Parameters to Module
• "Finished" Message by Means of Modules
In other words, the DP slaves must power up and be configured by the CPU (as
DP master) in the set time.

PROFIBUS Address of the DP Master

All PROFIBUS addresses are permissible.

From EN 50170 to DPV1

The EN 50170 standard for distributed I/O has been further developed. The
development results are included in IEC 61158 / IEC 61784-1:2002 Ed1 CP 3/1. In
the SIMATIC documentation we refer to this as DPV1. The new version features a
few additions and simplifications.
Some SIEMENS automation components already feature DPV1 functions. To be
able to use these new features you first have to perform a few small modifications
to your system. A detailed description of the conversion from EN 50170 to DPV1 is
available as FAQ with the title "Changing from EN 50170 to DPV1", FAQ
