4.6 Alarm Codes, Descriptions, and Suggested Actions
Description
System error
System error
The EEPROM does not contain valid fac‐
tory calibration information for a local AO
channel. Default calibration values are
used. The module is operational.
System error
System error
Indicates that at least one CAN node
failed during the initialization process. No
I/O operations are allowed on the node.
Indicates that at least one CAN node
failed during normal operation. This flag
is generated only if the node worked
properly during initialization but failed at
a later time. No further I/O operations
are allowed on the node. The communi‐
cation with the card will be stopped and
the card will set itself to failsafe output.
Indicates a failure of the CAN bus detec‐
ted during the CAN bus initialization.
No communication is possible with any
node. This can be as a result of either:
a) No CAN card is present, but yet at
least one card is defined in the database
b) The CAN hardware cannot communi‐
cate with a CAN device as a result of a
hardware error (e.g. broken or shorted
cable) and the PIC CAN module is re‐
porting a transmitter error.
Indicates a fatal failure of the CAN bus
detected during the normal operation.
This flag is generated only if the CAN
system worked properly during initializa‐
tion but failed at a later time. No commu‐
nication is possible with any node.
A read or a write was attempted to a
channel that does not exist.
Indicates that at least one serial number
has changed and that, as a result, the
CAN bridge PIC will soon reset. This is
normal as a result of a CAN node list
configuration change.
