The Operator Window

Fig The operator window

The operator window is placed at the upper edge of the screen, and lacks title row and
pushbuttons to iconify and delete the window. It is divided in tree parts, to the left
current alarms and messages are viewed, in the middle there are pushbuttons for some base
functions, and to the left there are pushbuttons configured for this operator place.

Status bar

The top row is a status bar. It shows who is logged in on which node. For tha current
node, and for all nodes that there are node supervision configured, an indicator for system
status is viewed. Green states that everything is all right, yellow indicates warning, red
error and flashing red fatal error. If you click on a node, the status graph for the node
is opened.

Alarms and messages

In the left part of the operator window alarm and messages are displayed.

The alarms are divided into four priority levels A, B, C and D, where A has the highest
priority and D the lowest. A alarms are marked red, B alarms yellow, C alarms blue and D
alarms violet. Furthermore there is the category Info messages that are marked with green.

In the upper field, the latest unacknowledged A alarm are displayed. Depending on the height
of the operator window, 2 to 5 alarms are viewed. There is also a button marked with a tick
to acknowledge A alarms.

In the lower field the latest unacknowledged B, C, D alarms, and info messages are viewed.
These alarms are displayed in priority order rather than in chronological order, i.e. if
there are unacknowledged B alarms, the latest of these will be displayed. Only if there are
no acknowledged B alarms, possible C alarms are viewed etc. There is also an acknowledge
button to acknowledge the B, C, D alarms and the info messaged.

An alarm is prevailing if the alarm condition still is fulfilled. This is marked with a
warning triangle to the left of the alarm text.
