22.2.Declaring variables #

You can declare your variables in the Variables Window:

22.2.1

 

There are four types of variables to use:

  • Input variables: use these variables for reading data from the PLC; each time the script is evaluated it first reads the PLC tags and stores them in the input variables
  • Output variables: after the script evaluation, the output variable values are written into the PLC; you can set whether it will write the value each time the script is evaluated or only upon change – this is controlled via the Update field (Always, On Change)
  • Value Memory: here you can declare your persistent variables; when a view is loaded, memory variable has its default value; you can change this value in   the script and it will prevail until you switch to a different view or close  the application
  • String Memory: String Memory variables are the same as Value Memory variables, but are of string type
