Keyword: ‎PROPERTY‎

Properties are an extension of the IEC 61131-3 standard and a tool for object-oriented programming.

Properties are used for data encapsulation because they allow for external access to data and act as filters at the same time. For this purpose, a property provides the accessor methods ‎Get‎ and ‎Set‎ which allows for read and write access to the data of the instance below the property.

You can add a property with accessor methods below a program, a function block, or a global variable list. Click “Project  Add Object  Property” to open the “Add Property” dialog.

You can add an ⮫ interface property below an interface.

When you copy a property that is inserted below a POU and add it below an interface, or if you move the property there, the included implementations are removed automatically.
