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