Adding Faceplates
Faceplates are used to view, interact and change properties for devices and other
process objects. The operator of the plant opens the faceplates by clicking on
objects in graphic displays. For more information about the operator handling of
faceplates, see Industrial
In this example we will create a faceplate aspect that activates the start signal for the
Motor "SimpleOnOffMotor". The faceplate is created on the object type.
Before starting this section a new signal named "Motor_Start" should be added to
the object type as shown i chapter Creating the Device Object Instances.
To create the faceplate, follow the steps below.
1.
Go to the Object Type Structure, select the PLC Faceplate Templates. Copy the
"Faceplate standard".
2.
Then select your object type for which a faceplate is required, e.g.
SimpleOnOffMotor, and paste the copied "Faceplate standard".
3.
Open the Config View for the faceplate aspect, by using the context menu
(right-click) on the aspect.
4.
Select the Buttons tab.
5.
Double-click the Object column in the row with a 1 Icon and browse to the
newly created "Motor_Start" signal.
6.
Click on the Property Name column and select the value property. (Resize the
window if the screen does not show up properly.)
7.
Select property type "boolean" and property value "true" and click OK.
8.
Click on the Enabled column and edit the code to the following:
iif($'./[Control Structure]:ObjectPCA:LOCK'=3,True,False).
9.
Now we have configured the 1-Icon button, when the button is clicked, the
value true will be sent to the PLC signal Motor_Start if the object is reserved
(e.g. LOCK=3).
10. Click ToolTip text and write "start motor" in the box, click OK.
11. Click Apply.
