This example shows how to use the Industrial Edge app Modbus TCP Connector.
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.
These PLC variants are supported:
- Schneider Quantum TCP/IP 140 CPU 113 03
- Schneider TSX Premium TSXP573634
- Schneider TSX Momentum 171CCC98020 (TCP/IP)
- Schneider Micro TSX 3710001
- Schneider M 340
- Schneider TM218LDAE24DRHN
- Schneider TM238LDD24DT
- Schneider TM258LD42DT
- Siemens SIWAREX WP231
- Siemens SIWAREX WP241
The Modbus TCP Connector is an application that runs on the individual IED. Connections can be configured using the IIH Configurator 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.

You can find further information about the following steps in the Configuration documentation:
- Overview
- Install Modbus TCP Connector
- Configure IE Databus
- Configure Modbus TCP via IIH 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:
