"SIMATIC S7-DP-Slave"
The ET 200M distributed I/O system is a constituent part of the SIMATIC S7 automation
system.
In other words,
programming the ET 200M in the DP master system as well as for the commissioning and
diagnostics. Special services and functions of the IM 153-2 (e.g. configurable FM) can be
used to their full extent only in the SIMATIC S7 / PCS 7.
If you use the ET 200M on a DP standard master (e.g. S5-95U), the configuration tool will
also provide support with the GSD file, but, for example, you must pay attention to the
technical data (project data) of the DP master (possible parameter assignment and
diagnostics message frame lengths etc.).
The PROFIBUS standard IEC 61784-1:2002 Ed1 CP 3/1 also includes the DPV1-mode. You
can use this mode only if you integrated the GSD-file Revision ≥ 3.
The GSD-file Revision 2 remains available and hence the compatibility with earlier versions
of the IM 153-x is assured.
Components
