A.1 A.1 Connection point recognition
A.1.1 Overview
Introduction
You can divide a system into several zones or functional areas by using several terminal
boxes. For this purpose it may be necessary for different system screens to be displayed,
depending on the terminal box used.
This is achieved by means of connection point recognition.
Note
The following sections are intended for the configuring engineer of the HMI device.
Note
If the same screens and functions are used predominantly for all PLCs and the PLCs are of
the same type, the configuration can be designed in such a way that only one PLC
connection is configured.
The configuring engineer can enable you to switch between the various PLCs usig a single
operating object.
Connection point recognition
You can implement the connection point recognition as follows:
• Reading out of the box ID set in the terminal box by the HMI device
• Wiring the terminal box to a digital input of the PLC.
Note
Connection point recognition via box ID
The solution with box ID functions for different system configurations.
