General Information

Overview

EcoStruxure Machine Expert Twin provides the Connections view that allows you to create connections to your controllers or higher level systems. A general description of the Connections view is provided in the EcoStruxure Machine Expert Twin Getting Started User Guide.

This document provides detailed information on how to configure the individual connection types for the supported communication protocols.

Supported Communication Protocols

By default, the following communication protocols are supported:

Address-based communication protocols:

  • Siemens

  • Modbus

  • Serial (Raw)

  • XCom

NOTE: For address-based communication protocols, perform the configuration offline before a connection can be established.

Tag-based communication protocols:

  • Beckhoff ADS

  • Ethernet/IP - CIP Browsable

  • OPC UA Client

NOTE: For tag-based communication protocols, establish a connection to the controller to display the available variables.

Messages-based communication protocols:

  • STC/ETX

  • 3964R

  • RFC 1006

Configuring Connections

You can configure a connection in two steps:

  1. Create and manage connections in the Connections view.

  2. Select a connection in the Connections view and configure the corresponding settings in the Properties view.

Both the Connections and the Properties views provide general settings and commands that apply to all types of connections. They are listed in this chapter. The settings and commands that are specific to a certain type of connection are listed in the individual chapters.

General Commands of the Connections View

The Connections view provides the following general commands in the contextual menu upon right-clicking a connection in the list:

Command

General Parameters of the Properties View

Auto Connect

Select the check box to establish the selected connection automatically when opening the EcoStruxure Machine Expert Twin project.

Auto Connect Delay

When Auto Connect is selected, enter a delay (in ms) that must elapse after the EcoStruxure Machine Expert Twin project has been opened before the attempt to establish the connection.
