Watch- and Recipe Manager \ Extensions¶
Note
Before you can use Watch- and Recipe Manager, it has to be activated.
For this, check .
The Watch window displays the values in a table oriented view.
The table display is used in both offline and online mode. It is not necessary to switch on/off monitoring mode to insert or delete a variable. It is possible to insert and append a variable in online and offline mode at any time. In addition it is also possible to add an address range.
The online value is displayed in IEC 61131-3 editor in online mode only.
A “+” will appear in the first column in case of Function Block instances, structured variables and arrays. It allows to expand and collapse them.
The editor allows manually to
- add watch entries
- delete watch entries
- change the name of a watch entry.
In online mode, the prepared value can be defined with a dialog. More than one prepared value can be selected. It is possible to enter the same value for all of them. One or more prepared values can be sent to the PLC via .
Tabular Editor
Each watch list is viewed in a separate tabular editor window and multiple windows can be opened at the same time. In this case the available watch lists will be shown as entries in the “Resources” tab indented below the Watch and Recipe Manager. Each can be opened by a doubleclick on the entry.
The tabular editor contains columns for name, address, value, prepared value, recipe value and comment of the watch variable.
name: Here a variable identifier according to the following syntax must be entered of an address in standard format:
<POU name>.<variable name>
In case of global variables the POU name is dropped. The variable name can be multilevel. Addresses can be entered directly (e.g. “%IB0.0”).
Example \ for a multilevel variable:
PLC_PRG.Instance1.Instance2.Structure.Component
Example \ for a global variable:
globalvar.component1
address, comment: As specified in the declaration of the variable.
value: In online mode here the current value of the variable is displayed (Monitoring).
recipe value: Here a value can be entered, which will be transferred to the PLC when command Write Recipe: ‘Extras’ \ ‘Write Recipe’ ‘Extras’ \ ‘Write Recipe’ is applied on the whole watch list. The recipe values of all variables of the list can be replaced by the current values from the PLC by using command Read Recipe: ‘Extras’ \ ‘Read Recipe’ ‘Extras’ \ ‘Read Recipe’.
In case of function block instances and structured variables a plus respectively minus sign appears in front of the name in the first column. It serves to expand resp. collapse the list of components. For function block variables the context menu is extended by the items ‘Open function block’ and ‘Open instance’.
By a double-click on a non-editable position within the editor window, the table gets adapted to the window width and the column widths get optimized.
1-Window-Editor
There is only one bipartite editor window, in the left part of which you find all available watch lists. For the list currently selected the right part of the window shows the associated variables. This editor view is opened via object ‘Watch- and Recipe Manager’ in the ‘Resources’ tab in the Object Organizer. The watch variables are entered line by line and a recipe value can be assigned to each by “:=”.
Adding variables to watch lists is possible in offline mode by typing, or in online mode directly out of the POU editors. See Creating watch lists: Creating Watch Lists, Recipes Creating Watch Lists, Recipes
A ‘Cross Reference List’ can be called directly from a watch list, when one of the watch variables is selected. In this case the command Show Cross References: Show cross references Show cross references in the Extras menu or in the context menu is available.
