retries, segment no.) cannot
be written.
Slave not visible in DCS
Diagnostic module error or
module missing
ADM: System maintenance
required

Problems with Gateway Operation

Symptom
Built-in slave does not accept the address
assigned via the DIP switch on the
motherboard.
Default values are not taken over when
restarting with default settings.
62
Possible cause
Poor signal quality
■
Hardware error
■
Devices use different firmware
versions.
Device was not rebooted.
Redundant system, but built-in
slave was not added to cyclic
data exchange.
PA bus master parameters are
write-protected. Reason: Built-
in slave is in cyclic data
exchange using PA bus
configuration module.
Respective segment is
■
deactivated
Poor signal quality on PA
■
side
Diagnostic module is defect or
was removed (by active ADM
alarm observer only).
At least one monitored system
value has violated the preset
limit.
Remedy/Background
Reboot gateway.
In case of redundancy: Restart both
gateways at the same time.
Caution: No redundancy available while
booting!
In case of redundancy: Restart both
gateways at the same time.
For detailed information, see chapter 6.3.6.
Caution: No redundancy available while
booting!
Remedy
Perform physical layer
■
diagnostics.
Send gateway to Pepperl+
■
Fuchs.
Harmonize firmware versions.
Reboot device. Firmware is
not active until device was
rebooted.
Add built-in slave to cyclic
data exchange
Use different module to
configure cyclic data
exchange.
Harmonize number of
■
PA segments at gateway
and actual number of
existing segments.
Perform physical layer
■
diagnostics on PA side
with advanced diagnostic
module.
Replace diagnostic
■
module
Switch off ADM alarm
■
observer
Perform diagnostics with the
DTM diagnostic manager for
detailed information.
For further information see the
documentation on the
"Advanced Diagnostic Module
HD2-DM-A".
