Diagnostics Monitor
The Diagnostic Monitor (ROA Diagnostics) application is a tool for
monitoring the status of the MIDAS IV system. In Diagnostic
Monitor, you can view the status of a CDU (Central Data Unit), ROA
(Remote Object Architecture) objects and ROA users. You can also
check the location of a sensor.
When you get an Internal Event message in Event Monitor, there may
be a problem with the CDU. In such a situation, you need to use
Diagnostic Monitor to view the system status more closely. When
there is a Technical Event message in Event Monitor, you need to use
Diagnostic Monitor to look up the location of the sensor causing the
event.
CAUTION
Diagnostic Monitor is also an installation tool used by Vaisala
personnel. For this reason, it contains some functions you must not
use. Incorrect use of these functions can result in serious system
problems.
This manual includes instructions only for those functions that you
can safely use in your troubleshooting tasks. Do not use functions
that are not covered in this manual.
When starting troubleshooting with Diagnostic Monitor, you need to
connect to the system in question.
1. Select System - Connect.
2. The Connect window appears.
3. Select the CDU (for example MIDAS IV TACMET) and click
OK.
4. The Statuses tab appears.
