Message explanations
385585/C A-73
Stack overflow (see message)
Description: BITE (Built In Test Equipment) has checked the bottom 1024 bytes of every stack
and detected that one of these data areas has been used or written to.
•
It is an indication that somewhere in the software, a task has used more
stack than assumed to be normal,
•
or a software failure has caused an uncontrolled memory write, accidentally
being in the stack area.
Possible
consequences:
•
If the alarm is caused by an excessive stack usage from a task, and the free
stack area for the actual task is not near zero (i.e. closer to 1024 than to 0),
it is possible that the system would continue to function without problems,
•
but if it is caused by an uncontrolled memory write, the functional
consequences are unpredictable.
•
The PS (Process Station) may stop.
Corrective
actions:
•
As indicated in the alarm-text, some extra information is found in a system
message received simultaneously as the alarm, containing size of the
remaining stack, and indication of which task is the stack owner. Note error
data and operational information.
•
Contact Kongsberg Maritime Service.
Swbd/Generator/Thruster/Reserved connection failure
Description This message is reported if the connect signal has a fault status.
The reason for the fault may be an error in the digital input interface or in the
cabling.
The method of detection is by monitoring the status of the digital input signals.
Additional
information
The identifier for the connection.
Possible
consequences
The DP system will keep the status of the signal as it was when the failure
occurred. I.e. the DP system will not detect any changes for the connect signal.
Corrective
actions
Check cabling. Replace appropriate input interface.
System file decode error
Description: There was a file decode error when decoding the ASCII (American Standard Code
for Information Interchange) system parameter files or the ASCII files do not
exist.
Additional
information:
Explanatory text
Possible
consequences:
The system parameters were not read properly. The system may become unstable
and the PS (Process Station) may stop.
Corrective
actions:
Switch from DP to Manual control. Try to reset the PS. Contact Kongsberg
Maritime Service.
