Possible cause
Device has not been re-
booted
Redundant system, but
Built-In-Slave has not
been added to cyclic data
exchange
PA-Bus-Master parame-
ters are write-protected
because Built-In-Slave
has been added to cyclic
data exchange using PA
bus configuration module
Respective segment is
deactivated
Poor signal quality on PA
side
Diagnostic Module is de-
fekt or has been removed
(by active ADM Alarm Ob-
server only).
At least one monitored sy-
stem value has violated
the preset limit
At least one monitored sy-
stem value has violated
the specification limit
At least one monitored
segment value has viola-
ted the preset limit
At least one monitored
segment value has viola-
ted the specification limit

Remedy
Reboot device. Firmware
is not active until device
has been rebooted
Add Built-In-Slave to cy-
clic data exchange
Use different module to
configure cyclic data ex-
change
Harmonize number of PA
segments at Gateway
and actual number of exi-
sting segments
Perform Physical Layer
Diagnosis on PA side with
Advanced DIagnostic Mo-
dule
Replace Diagnostic
Module
Switch off ADM Alarm
Observer
Execute diagnosis with
DTM Diagnostic Manager
for detail information (for
further information see
Advanced Diagnostic Mo-
dule HD2-DM-A manual).
