Configuring with COM 115F
•
Transferring the error DB via SINEC L1
If you have configured a SINEC L1 LAN, you can send the body of the error DB with the error
message code to the master for evaluation. The S5-115F automatically sends the body of the
error DB to the master in the event of a fault.
You can choose one of the following three options:
S =
Only send an error message to the master if the error causes the S5-115F to assume STOP
status
R =
Send all error messages to the master (even those when the S5-115F remains on RUN)
N =
Do not send any error messages to the master.
•
High-level protection of the destination slave number
High-level protection of the destination slave number is necessary when several SINEC L1
slaves are configured with the same mailbox length. However, we recommend that you also
use high-level protection of the destination slave number in all other cases.
The S5-115F carries out high-level protection of the destination slave number automatically.
Please note the different message structure ( Vol 1, 7.2.2 of the Manual).
•
Change-of-message monitoring
Facilities for recognition of a change of message are essential if you want to send safety-
related broadcast messages via the SINEC L1 LAN. Broadcast messages are messages addressed
to the master and all slaves at the same time. We recommend that you use the monitoring
facility for recognition of a change of message even if you are not sending broadcast
messages.
The S5-115F handles monitoring for a change of message automatically. Please note the
different message structure ( Vol 1, 7.2.2 of the Manual).
Note
If you assign parameters for change-of-message monitoring, the S5-115F will also
automatically perform high-level protection of the destination slave number.
