8.2.6 PLC Configuration in Online Mode
In online mode the PLC configuration displays the states of the inputs and outputs of
the PLC. If a boolean input or output has the value TRUE, the little box at the
beginning of the entry line in the configuration tree will get blue, non-boolean values
will be added at the end of the entry line (e.g. "=12").
The boolean inputs can be toggled by mouse-clicks. At other inputs a mouse-click on
the beginning of the line opens a dialog, where the value can be modified. The
modified value will be set in the PLC as soon as the dialog is closed with OK.
Also regard the target specific possibilities for online diagnosis.
8.3 Alarm configuration
8.3.1 Alarm configuration, Overview
The alarm system integrated in »PLC Designer« allows to detect critical process states,
to record them and to visualize them for the user with the aid of a visualization
element. The alarm handling can be done in »PLC Designer« or alternatively in the PLC.
For alarm handling in the PLC please see the target settings in category 'Visualization'.
If supported by the target system, the dialogs for 'Alarm configuration' are available in
the 'Resources' tab.
Here you define Alarm classes and Alarm groups. An alarm class serves for the typing
of an alarm, that means it assigns certain parameters to the alarm. An alarm group
serves for the concrete configuration of one or several alarms (which get assigned a
certain class and further parameters) for the use in the project. Thus a class is useful
for structuring the available alarms. The different alarm groups are defined by the
user by inserting appropriate entries below the header 'System' in the configuration
tree.
For the visualization of alarms the 'Alarm table element is available in the PLC
Designer visualization. Using this table the user can watch and acknowledge alarms.
The language of the displayed alarm message texts might be switched dynamically.
If a History, i.e. recording of Alarm Events should be written to a log-file, such a file
must be defined and for each alarm group the saving behaviour must be defined.
When you open the 'Alarm configuration' in the Resources tab, the dialog 'Alarm
configuration' opens with a bi-partited window, which concerning the mode of
operation is similar to that of the PLC Configuration or Task configuration. In the left
part the configuration tree is displayed, in the right part the appropriate configuration
dialog will be opened.
