Watch Window

This toolbox is used to add variables to a dedicated Watch Window to view its value in real time.

• • PLC "Programmable Logic Controller" A Programmable Logic Controller, PLC, or Programmable Controller is a digital computer used for automation of industrial processes, such as control of machinery on factory assembly lines. Used to synchronize the flow of inputs from (physical) sensors and events with the flow of outputs to actuators and events variables viewed in the Watch Window are saved as a part of the project.
    • This means that the next time you open the project, those variables are pre-loaded in the Watch Window.
    • This does not apply to AKD variables, which are not saved with the project.
  • While variables may be changed, locked, or unlocked, parameters are not.
    • See Force a Variable for more information.
    • AKD parameters in the Watch Window are read only.

Multiple Watch Windows

The KAS-IDE "Integrated development environment" An integrated development environment is a type of computer software that assists computer programmers in developing software. IDEs normally consist of a source code editor, a compiler and/or interpreter, build-automation tools, and a debugger allows you to group several variables in a single Watch Window.

• A maximum of 10 different Watch Windows is allowed.
• Each window is shown as a tab with its own label.

Explanation for each icon:

• You can also add an existing variable in the watch window directly by using drag-and-drop from the Dictionary or the PLC editors.

Each variable in the table widget has this information:

Field	Description
Name	Lists the variables as well as structure, arrays, and expressions. Double-click a variable (or press the F2 key when the variable is selected) to edit its name (except for structure and array members).
Value	When the application is running, this is the variable or expression's value. Double-click a value to force modification of the selected variable.

The contextual menu allows you to:

• Add a variable.
• Remove a variable.
• Remove all variables.
