6.3.11—Troubleshooting and Tuning
The MicroNet CPU module runs off-line and on-line diagnostics that display troubleshooting messages
through the debug Service Port and AppManager. Off-line diagnostics run automatically on power-up and
when the Reset switch is asserted. On-line diagnostics run during normal Control System operation when
the GAP application is active. More information on diagnostics tests, subsequent LED flash codes, and
serial port messages is contained in the VxWorks manual.
