13.20 Watch List Editor
The watch list functionality is provided by the "Watch List" plug-in.
A watch view can be opened via the Watch command submenu (by default in the View
menu). It provides an editor for creating watch lists.
A watch list can be used to define and monitor a list of expressions of various objects
and to write or force values to those expressions on the controller in online mode. By
default four individual watch lists can be set up in the watch views Watch 1, Watch 2,
Watch 3, Watch 4. View Watch all Forces in online mode always gets filled
automatically with all currently forced values of the active application.
13.20.1 Create watch list
To set up a Watch <n> list in the watch view perform a mouse-click in a field of the
Expression column to open an edit frame. Enter the complete path for the desired
watch expression:
Syntax for watch expression:
<device name>.<application name>.<object name>.<variable name>,
Example: "Dev1.App1.PLC_PRG.ivar" (as shown in the image below)
The type of the variable will be indicated by an icon: = input, = output, = "normal"
variable. If a comment has been added to the declaration of a variable, it will be
displaced in column Comment.
After having closed the edit frame the type will be added automatically in column
Type.
The Value column will be used in online mode for displaying the current value of the
expression.
To appoint a prepared value to a variable you may click in the assigned field of the
column Prepared value and directly type in the desired value.
In case of a boolean variable the handling is even easier: You can toggle boolean
preparation values by use of the Return or Space key according to the following order:
If the value is TRUE, the preparation steps are FALSE -> TRUE -> no entry; else, if the
value is FALSE, the preparation steps are TRUE -> FALSE -> no entry.
