There
is a system overview panel for the diagnostics of a WinCC OA system. The system
overview panel is a part of the version by default. The panel
provides several possibilities for setting the error weighting
in the complete system as well as for displaying the current status
in the system (e.g. Manager state, RAM memory, hard disk space,
...). The system overview panel can be used for each configuration
(Single system, redundant system or distributed system). Merely
the appearance of the panel is changed via the different configurations.
Single
system components can be controlled and provided with a weighting
in a system. The weighting is used for the calculation of the
error status in case of errors. Components that are controlled
and for which the error status is calculated are e.g. managers,
TCP connections, PLC connections, hard disk capacity, RAM memory
etc. The weighting is a number between 0 and 999 and the user
can assign it specific to the components. How grave the error
is and which number should be set for the weighting is defined
by the user. The loss of a PLC connection is e.g. configured with
a higher weighting than the failure of a UI.
The optimum error state of a system is 0. The error weighting
is configured in the system overview panel.
In
a redundant system the switching of the active/passive level for
the redundant computers is executed in the system overview panel
(therefore you can find specific buttons in the panel). In not
redundant configured systems the overview panel is used for displaying
the status.
In
the following chapter the system overview panel is described in
case of a single, redundant or distributed system. |
