Tips for users of the ET 200U
The modules of the ET 200U have address identifiers.
There is a list of all modules and their address identifiers at
the end of this chapter.
Intelligent I/O modules (IPs) and communications proces-
sors (CPs) are treated like analog modules.
The following table shows how the modules are repre-
sented:

The foldout at the beginning of this manual contains a table
explaining the “KM” and “KH” formats in detail.
What do DP Siemens and DP Standard mean?
DP Siemens is the bus protocol developed by Siemens. In
cooperation with the PROFIBUS user organisation, SIE-
MENS has extended the bus protocol, which is now an
open, multi–vendor system. This extended bus protocol was
submitted to the German Electrotechnical Commission
(DKE) and adopted as national draft standard DIN E 19245,
Part 3.
The DP Standard bus protocol complies with the draft stan-
dard PROFIBUS DIN E 19245, Part 3.
The actual advantage of the standardized bus protocol for
you is that all ET 200 partners are now able to communi-
cate provided they comply with the draft standard PROFI-
BUS DIN E 19245, Part 3.
The figure below shows the sequence for an ET 200U sta-
tion; a detailed description is given on the following pages.
At the beginning, it is specified whether the ET 200U acts
according to either DP Siemens (ET 200U) or DP Standard
(DP slave ET 200U).
All the other displays are identical for both ET 200Us.
