Configuring the Broadcast Mode
Introduction
Assigning Parame-
ters to CP 541
Step
1
Load DB1 into the programmer.
2
Enter the station number of the CP 541 with
parameter TLN in frame SL2.
3
Write the modified DB1 into the CP 541.
4
Switch the CP 541 to RUN.

Assigning Parameters to the CP 541 for the Connections
You can easily establish the broadcast mode with the parameters stored in the
default DB1.
You assign parameters for the broadcast mode via the CP 541 as shown in the
following table.
Action
In the connected programmable controller, you must observe the following
points when assigning parameters:
The station number set in the CP 541 must be identical to the node ad-
dress of the connected programmable controller.
Install the broadcast mode in the connected programmable controller us-
ing node address 31.
Each broadcast message can contain up to 64 bytes of data.
If you cannot receive a broadcast or the transmitted broadcast cannot be re-
ceived by other stations, you must modify parameter BSAP (broadcast ser-
vice access point) in the COM block of DB1.
Follow the instructions in Appendix C and Appendix G.
Parameter BSAP in the COM block has the internal default value 52. If you
do not change parameter BSAP, you must not remove the comment charac-
ters for the COM block.
Remark
–
The station number of the CP 541 must be
identical to the node address of the con-
nected PLC.
–
Only upon transition from STOP to RUN
will the modified DB1 be stored in the EE-
PROM of the CP 541.
