When looking at a station’s output, you are usually troubleshooting.
As part of troubleshooting, you should always check the station’s
log histories, which should contain recently recorded station errors
and (if configured) warnings. This information may help when evaluating
live output from the station.
You are connected to a platform and its running station. The
station has been configured with the LogHistoryService.
- Expand and
double-click LogHistoryService.
The LogHistoryService’s AX Property
Sheet opens.
- Expand History Config and Last Record.
All properties are available for configuration.

By default,
the log level property Minimum Severity is set
to Info. This is the minimum message type to be sent
from station output to the log.
- You may wish to change this to Warning.
The station maintains a buffered history (LogHistory)
of some of the messages seen in the station’s standard output.
For more information about log history, refer to the Niagara Histories Guide.
