Transmission via PROFIsafe
Once SLA has been parameterized and selected, the monitoring results are transmitted in
status words S_ZSW1.8 or S_ZSW2.8 (see Chapter "Process data (Page 217)").
Note
Response to bus failure
If p9580 ≠ 0 and SLA is active, in the event of a communication failure, the parameterized
ESR reaction only occurs if a STOP with delayed pulse suppression when the bus fails has
been parameterized as the SLA response (p9579 ≥ 10).
Transfer via SIC
Once SLA has been parameterized and selected, the monitoring results are also transmitted
in SIC in status word S_ZSW1B.8 (Chapter "Safety Info Channel and Safety Control Channel
(Page 251)"). You will find this status word in telegrams 700 and 701.
