  • Ctrl + Spacebar opens this dialog box

KAS-IDE automatically checks if the variable already exists. When the variable is new, you have to:

  • Select its type in the drop-down menu: for FBD and FFLD, it is set by default according to the In or Out data type of the function block
  • Specify where it is defined: the default is the current PLC program, but you can choose to make the variable Global or declared as a retain variable
