7.6.3 MCN System Messages
During system initialization and operation, MCNRCD may detect various system
errors. These system errors will always be logged to the screen, regardless of the
Show Errors on Screen option setting. If the Log Errors to Disk option is
enabled, then these system errors will also be logged to the MCNERR.LOG file.
The following system errors are detected and logged by MCNRCD:
•
Invalid configuration data received. Error code F0
The specified Comparator I/O Module is not compatible with this version of
MCNRCD.
•
Comparator communication failure detected. Error Code F1
A communication link failure has occurred between the specified Comparator
I/O Module and the comparator it is attached to. Comparator link failures will
only be reported if the Comparator I/O Module implements Link Failure
Reporting. Refer to the hardware reference manual of the Comparator I/O
Module being used to see if it supports this feature (for example, Link Failure
Reporting is supported in the AIB module, but not in the CIB module).
•
Module error has been corrected. Error code F3
The previously reported Comparator I/O Module error has been fixed and the
module is now ready for normal operation. This will happen, for example, if
an AIB module that has reported a comparator communication link failure
resume communications with the comparator (i.e. the cable between the AIB
and the comparator was disconnected, causing the comparator link failure
message, and was then reconnected).
•
No configuration data received from module. Error code F4
MCNRCD could not establish communications with the specified Comparator
I/O Module. The module is configured in the Group Configuration File of the
loaded screen file, but the module is not connected to the MCN network or is
not powered.
MCNRCD will periodically attempt to initialize previously unrecognized
modules so that status monitoring and control can begin with that module.
Generally, a module connected to the network or powered up after the screen
file has been loaded should be brought on-line within a couple of minutes.
•
Module is back on-line. Error code F5
MCNRCD has resumed communications with a Comparator I/O Module that
previously had a network communication link failure. When the module is
back on-line, MCNRCD is able to resume normal status monitoring and
control of the Comparator I/O Module.
