7 Configuring PROFIBUS DP When Using the
BM141/BM142
During startup, the PROFIBUS DP master sends a configuration frame to the ET 200X containing a
DP identifier for each ET 200X expansion module. The DP identifier is used to distinguish individual
modules (see /4/).
The following identifiers apply to the CP 142-2 depending on whether the special or general ID format
is used:
Special ID format:
ID (hexadecimal)
Byte 0
Byte 1
Byte 2

General ID Format:

If you use a SIEMENS configuration tool for your DP master (for example STEP 7 or COM
PROFIBUS), these settings are generated automatically.
