Description
Required action
Hardware failure
Error
ON only
Created when the module
hardware supervision
detects A/D saturation of an
error in the digital input
potential sampling.
Check
connection of
digital inputs.
Check
connection of
analog inputs.
Missing stream
Error /
Information
ON /
OFF
Error log created when the
module does not receive on
the SAM600 system bus a
sampled values stream that
it is configured to merge.
Information log created when
the error condition vanishes.
In case of the
error log: check
connection of all
SAM600
modules to the
SAM600 system
bus.
Path delay failure
Error
ON /
OFF
A link failure was detected
on SAM600 system bus or
on a SAM600-TS access
point supporting time
synchronization.
Check physical
connections.
System bus
redundancy error
Error
ON /
OFF
A link failure was detected
on SAM600 system bus.
Check physical
connection of
SAM600 system
bus. Check
power supply of
SAM600
modules.
Process bus 1
redundancy error
Error
ON /
OFF
A link failure was detected
on SAM600-TS process bus
connection supporting time
synchronization.
Check physical
connection.
Check correct
function and
configuration of
IEEE 1588 on
connected
device.
RTC to PTP sync
fail
Error
ON only
The SAM600-TS module
failed during startup to apply
its battery-buffered time
information to other SW
components.
Call help line.
Time sync failure
Error /
Information
ON /
OFF
Error log created when the
module supervision detects
a mismatch in the sample
synchronization status.
Information log created when
the error condition vanishes.
Depending on
the Time
synchronization
setting check the
connection to the
external GPS
time source /
master clock / 1-
PPS source.
X10* link status
Information
ON /
OFF
Created when the link status
of the respective network
port changes.
None
