WinCC Basic V13 SP1 – Simple Sample: sending HMI status to controller

“Simple Samples” are small projects that demonstrate simple features. The target is give a quick overview about the theme and be used as start point for related discussions. Follow there are a short description and the configuration main steps.

Description:

Some applications demands that the controller (PLC) knows if an HMI is operating (i.e. communicating).

In this simple sample, the area pointer is used to send the HMI status to the controller. A simple controller logic are used to interpreter the information.

Requirements:

WinCC Basic V13 SP1.

Project with a minimum configuration (stop button, tags, etc.).

Configuration main steps:

• Configure a controller – HMI communication as usual (e.g. by dragning and droping a controller tag to the HMI screen).

• Set the coordination area pointer: HMI → Connections → Area Pointer → Set “Coordination” → Address → define a free word address on controller.

• In the controller, it is necessary to monitor the word third bit, checking if it changes in less of 2 seconds (e.g. by positive edge detection plus timer function).
