3.4 Fieldbus interface
Response to CPU / master STOP
If the fieldbus interface is interrupted, all control signals are set to 0.
Note
This is only relevant in "automatic" mode.
Group diagnosis
The controller is informed of whether or not a group fault message is present in the device
when "I/O fault bits" on the SAP status tab (S1 = 1) is set. The AS-i master enters the S1
value in the list of I/O faults (LPF) that have been signaled. The controller can read this list
via the "GET_LPF" command and then query a specific diagnostic value from the slave (see
also
Diagnostics via parameter channel (parameter echo) (Page 84)).
The motor st
arter issues a fault message if a fault is present. In this case, the SF LED lights
up red.
Reference
For more information, refer to the documentation for your AS-i master.
