Main Processor System Logs
MON 2009-03-23
17:02:56 25 Cfg: Configuration file loaded.
17:02:56 26 IMB: LRAM power up test passed
17:02:59 51 ISaGRAF: Create Comms space (req=1024, max=1024)
17:03:06 22 A/S: Processor mode set to Active
17:03:06 26 IMB: Expander configuration complete
17:03:06 26 IMB: Found CI module - Chassis 1 Slot 7
17:03:06 28 IMB: Slave connection manager started - Chassis 1 Slot 7
17:03:06 33 NIO: Found TMR 24Vdc Digital Input - Chassis 1 Slot 1
17:03:06 33 NIO: Found TMR Analogue Input - Chassis 1 Slot 3
These logs show date-stamps at the start of each day (e.g.
MON 2009-03-23
above). Each entry has a
time stamp, the number and name of the task that wrote the entry (e.g.
26 IMB:
) and a text description
of the entry. Most entries will be due to normal operation. To find the current state of the system, read
the log from the bottom, up to the first ‘fault reset’ entry. Some possible entries are shown below.
NIO: Disabling interface (Rack 1 Slot
5), slice C
A module slice is being set offline by the processor;
this will appear in the I/O module as an 0x8741 fault.
Check the First-Line Diagnostics advice for a steady
red I/O module 'Healthy' LED
NIO: CLI error (FAIL) - Chassis 3 Slot 7
Slice C
The I/O module slice has stopped communicating
NIO: Lost (Rack 3 Slot 1) … A module has been removed
NIO: Simulating … The system is running without the module
NIO: Module(s)
removed/unconfigured/simulated
The processor is warning that it is still running without
all modules
IMB: Expander FCR fault set - … Communications via expander modules has failed
NIO: Channel 6 Discrepancy (Rack 6 Slot
5), slice C
I/O point measurement discrepancy; this will appear in
the I/O module as a 0x70nn fault. Check the First-Line
Diagnostics advice for a flashing red I/O module
'Healthy' LED
CLI Response Error FAIL - Chassis 2 Slot
11
A module is missing on startup
FPS: [Manual] System fault reset The reset pushbutton has been pressed
NIO: Linked (or) Unlinked Chassis 3 Slot
7 - Chassis 3 Slot 12
Two I/O modules have been partnered for a hot swap
(linked) or the partnership has been broken (unlinked)
NIO: Impending module removal set (or)
cleared - Chassis 2 Slot 9
The ejector tabs on this module have been opened (or)
closed. If the log reports alternating set/cleared
messages, the ejector switches are faulty.
NIO: Slice fault - Chassis 4 Slot 9 A module has a fault but is still running. Check the
First-Line Diagnostics advice for a flashing red I/O
module 'Healthy' LED
NIO: Module not properly configured -
Chassis 3 Slot 2
The I/O module has rejected its System.INI
configuration. It will have shut down on starting the
system.
NIO: Illegal 'standby' module state
(fatal) - Chassis 4 Slot 1
The I/O module was set Active but went back to
Standby. This probably indicates that it has rejected its
System.INI configuration.
IMB: Permanent minor fault (MBCU)
Chassis 4 Slot 13 FCR C
Indicates a permanent problem with system
communication to the given chassis, slot and slice.
