Assigning station

For some DP standard slaves you set the station number by means of the
software, e.g. for the ET 200C distributed I/O station or the DP/AS-I Link.
Note that the FB IM308C can be used to change the station numbers of DP
standard slaves only.
DP slaves whose station number can only be set by means of switches set in
the housing, or DP Siemens slaves: you cannot assign the station numbers by
means of the software.
To assign a station number to a DP slave, proceed as follows:
1. Configure the parameterization master IM 308-C and the DP standard
slave with the new station number using COM ET 200 Windows.
Tip: Use the highest possible baud rate for the DP standard slave.
2. Connect the bus to the IM 308-C and to the target DP slave which is to
receive a station number.
3. Connect the PG to the AS 511 interface of the CPU and set up a
configuration as shown in Fig. 9-2 :
