HMI DesignWINCCBASIC OVERVIEW OF FACEPLATE AND HMI UDT TECHNOLGIES

Faceplate Technology

What is a faceplate?

Why use a faceplate?

A faceplate is a group of HMI objects arranged and combined into a single object by the programmer.

These faceplate objects can be tailor made to your specific needs.

Faceplates are reusable from project to project.

Faceplates, if setup with a UDT interface, only have to be tagged out once.

Once this type of faceplate has been tagged out and debugged you never have to do it again.

Tremendous time savings during development, startup and life cycle.

Faceplate Technology

The following are a few faceplates I have created. These faceplates utilize an HMI UDT in their interface.

HMI UDT

An HMI UDT is a data type created by the programmer

In these examples, my UDT is structured exactly the same as my instance data block in my controller

You can then use this UDT to create faceplates with an interface that matches a corresponding function block in your controller

Why??? Because you only have to tag out the faceplate objects once. From then on all you have to do is copy and paste the faceplate and point it to its data block.

Let’s get started…

HMI UDT - Creating the UDT

HMI UDT – Assign the UDT to a DB

Faceplate – Tag objects to UDT variables

Faceplate – Tag objects to UDT variables

UDT Expanded

Using the faceplate

Create a tag, assign the data type, point it to correct data block

Drag and drop the faceplate from the library onto an area of the screen.

Assign it to the tag.

Done.

One object with one tag…
