When a faceplate is placed on a page (via drag & drop from the toolbox), it initially only contains the standard properties that each control element contains. The faceplate does not automatically publish all the properties of the controls it contains.

To access individual properties of internal control elements from outside, these must be defined in the Properties tab of the faceplate inspector .

Let’s take a look at this faceplate as an example:

It contains a label, three conveyor technology elements and two buttons. Here, for example, it may be necessary to be able to control the enabled property of the two buttons at runtime.

We can add further properties to the faceplate by first switching to the Properties tab.

In the right-hand input field Target property, we now select a property of an internal control element that we also want to control externally. In the left-hand input field Name, we then assign a unique name under which this property can be addressed in the faceplate.

If this faceplate is now placed, these two properties now appear in the control element inspector and can be changed in value or assigned rules.
