Response to CPU/Master STOP

This device parameter enables you to specify how the motor starter is to respond to
CPU/Master STOP:
● Retain last value:
The PIO is retained.
● Switch substitute value:

Group diagnostics

You use this parameter to specify whether diagnostics via the fieldbus interface is to be
enabled or disabled. If group diagnostics is parameterized as "block", no error messages are
transmitted.
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 137)).
The motor starter issues a fault message if a fault is present. In this case, the SF LED lights
up red.
