Configuring the Safety-Related Broadcast Mode
You can easily install the safety-related broadcast mode with the parameters
stored in the default DB1.
You assign parameters for the safety-related broadcast mode via the CP 541
as shown in the following table.
Step
Action
Remark
1
Load DB1 into the programmer.
–
2
Enter the station number of the CP 541 with
parameter TLN in the SL2 block.
The station number of the CP 541 must be
identical to the node address of the con-
nected PLC.
3
Write the modified DB1 into the CP 541.
–
4
Switch the CP 541 to RUN.
Only upon transition from STOP to RUN
will the modified DB1 be stored in the EE-
PROM of the CP 541.
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 safety-related broadcast in the connected programmable con-
troller.
Each safety-related broadcast message can contain up to 60 bytes of net
data.
If you cannot receive a broadcast or the transwithted broadcast cannot be
received by other stations, you must modify parameter BSAP (broadcast ser-
vice access point) in the COM block of DB1.
Follow the instructions in Appendices C and 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.
