7.6.1 Error Logging
MCNRCD provides the capability to continuously monitor your
comparator/voting receiver system. MCNRCD optionally reports detected errors
to the display screen and/or a log file. Maintenance and supervisory personnel use
these reports to track down intermittent system problems.
Errors are detected for all of the receivers in each MCN Group being monitored
by the loaded screen file, not just the receivers shown on the currently loaded
screen. Error conditions detected by MCNRCD include any receiver
Fails,
Disables
, or
Errors
. An error indicates some invalid comparator action.
An example would be if the comparator control lines showed a receiver as being
Voted and Disabled at the same time.
Each Group Configuration File can monitor up to 128 receivers when fully
loaded. When an error is detected, MCNRCD takes one of the following user
configured actions:
• The receiver information and error condition is shown on the screen.
• The error is written to the log file on disk.
• The error is ignored.
• The error is shown both on screen and logged to disk.
Selecting Error Logging Options
1. From the Logging menu select Options... to display the Log Options Dialog
Box.
2. To show errors on the display screen as they occur, select the Show Errors on
Screen check box with a mouse, or press the
H s
keys.
3. To log errors to disk select the Log Errors to Disk check box with a mouse, or
press the
H l
keys.
Errors are logged to disk and stored in a file named MCNERR.LOG.
The file size (in MB) for logging errors is set by the Command Line Option
switch ‘/En’, where n = 1 to 10. The default file size is 1 MB if no option is
given. See Section 7.8.1 for more details on the Command Line Options. Error
log entries are stored as ASCII text consisting of 107 bytes per log.
An Error log file size selection of 1 MB (default) can hold 9570 entries.
When the MCNERR.LOG
file is 90% full
, a warning beep and a percent full
message is on the top right of the menu bar are given on each subsequent log.
Pressing
F1
brings up the
On line help text
, giving you detailed instruction on
how to backup the log file. The On line help is available only when the
MCNERR.LOG file is over 90% full. If a copy of the MCNERR.LOG error log
file is desired, exit MCNRCD, copy the MCNERR.LOG to a new file name, and
then delete the MCNERR.LOG file.
