Designing HMI

Designing a link between human and machine

The HMI (Human Machine Interface) 155PH1 consists of a KTP400 Comfort panel from Siemens. 400 stands for the screen size, which in this case is 4.3". The resolution is 480 by 272 pixels.

For comparison: a Samsung Galaxy S22 smartphone with a 6.1" display has a resolution of 1080 x 2340 pixels. Regarding the design we are a bit restricted, but you can create a nice and clear design nevertheless, to facilitate the usage of the robot for the operator.

Click on the HMI 155PH1 in the Project navigation to create a template with Image management > Templates. In the course of the tutorial 3 images based off the templates will be created:

• Image_1 - Overview
• Image_2 - Messages
• Image_3 - Switches etc

The images and displays can be switched with buttons (click > action). The data exchange between PLC and HMI is managed by the data block DB122.

Next to the signal lamp text list, create a signal lamp called graphics list.
