This tutorial shows how to use the Industrial Edge application Modbus TCP Connector to establish a connection between an Industrial Edge Device (IED) and a PLC that supports Modbus TCP, a data communications protocol (client/server) that runs on Ethernet.

The Modbus TCP Connector is an application that runs on the individual IED. It can communicate with any Modbus TCP PLC that uses the standard protocol. Connections can be configured using the Common Configurato for Industrial Edge. The connector transfers the value series of selected data points from a PLC to the Databus. From there the data can be used within other Edge apps, e.g. the Flow Creator.

Here we configure a connection between a Modbus server and client. The IED acts as the Modbus client and the Modbus server can be any hardware that is able to instantiate standard Modbus communication. The data is published on the IE Databus. By using the application IE Flow Creator, we fetch the metadata of the Modbus TCP Connector, write some data on the configured tags and read out data.

• Access to an Industrial Edge Management (IEM) with onboarded Industrial Edge Device (IED)
• IEM: Installed system configurator for Databus
• IED: Installed apps Modbus TCP Connector, Databus, Databus Gateway, Flow Creator, Common Configurator, IIH Registry Service, Common Import Converter, IIH Essentials (optional)
• IED is connected to Modbus TCP Server
• Google Chrome (Version ≥ 72)

• Industrial Edge Management (IEM Pro) V1.7.6
  • Databus Configurator V2.3.2-2
• Industrial Edge Virtual Device (OS) ievd-1.16.1-1-a
  • Modbus TCP Connector V 3.0.1-0
  • Databus V2.3.3-2
  • Databus Gateway V1.10.0-0
  • Flow Creator V1.17.0-2
  • Common Configurator V1.10.0-4
  • IIH Registry Service V1.10.0-0
  • Common Import Converter V2.2.0-0
  • IIH Essentials V1.10.3
• Modbus TCP Server - ModRSsim2 Modbus TCP Server Simulator

You can find further information about the following steps in the Configuration documentation:

• Overview
• Install Modbus TCP Connector
• Configure Databus
• Configure Modbus TCP via Common Configurator

As soon as the Modbus TCP Connector is configured, data can be transfered.

You can find further information about how to handle the data via the IE Flow Creator in the Usage documentation:

• Read metadata
• Write data
• Read data
• Use IIH Essentials
• Use Common Configurator
