Modbus to Ethernet Converter full guide

Sharing Modbus Data to Ethernet

Serial to Ethernet Connector is a specialized software application that enables you to work with Modbus to Ethernet IP data. The app lets you share data from a locally connected Modbus device over an Ethernet network. This allows network-connected users to interact with the device as if they were directly physically attached to it. The Modbus to Ethernet software enables you to work with up to 500 devices simultaneously and access them from any location that is connected to the network.

Getting started with this Modbus to Ethernet IP converter is simple. All you need to do is download and install the software on the computer that is attached to the Modbus device you wish to share, which will be referred to as the server. The app also needs to be installed on all the client computers which will remotely access the device. Once that is done, you ‘Share’ the device from the server and “Connect’ to it from the clients.

The clients obtain the full functionality of the device in the same way as they would with a direct physical connection. This Modbus serial to Ethernet converter solution transfers serial data over the network and uses virtual serial port technology to make it available to the client computers.

This Ethernet IP to Modbus TCP converter runs as a Windows service in the background, so you don’t need to keep the application open all the time. All connections will be automatically reconfigured after rebooting the system for increased efficiency. A nice feature of the software is that you can also back up a configuration by moving it to another machine.

Serial to Ethernet Connector runs on the Window and Linux operating systems. Currently, the Linux edition is strictly a command-line tool. This Modbus to Ethernet converter allows you to share devices between computers in a mixed Linux and Windows environment.

FAQ

Modbus is a serial communication protocol developed by Modicon® in 1979 for use in their programmable logic controllers (PLCs). It employs a slave/master methodology of enabling serial data to be transferred between devices. The Modbus Master is a device that requests data from the slave devices and can also write to them. In a standard Modbus network, there is one Master and up to 247 Slave devices. Slaves have unique addresses numbered from 1 to 247 and their role is to satisfy the requests made by the Master.
Modbus RTU, or Remote Terminal Unit, is one of the transmission modes that were defined when Modbus was originally developed. There were two modes, RTU and ASCII, which are meant to be used with devices that support the RS232, RS422, and RS485 serial data transmission protocols.
Modbus TCP/IP, which is also called Modbus-TCP is just the Modbus RTU protocol with the addition of a TCP interface running on Ethernet. Data is organized and interpreted using the rules defined in the Modbus messaging structure and is implemented similarly no matter which data transmission medium is used.
The only real difference in the Modbus RTU and Modbus TCP/IP protocols is that Modbus RTU works at the serial level and Modbus TCP/IP operates at the Ethernet physical layer. A six-byte header is employed with Modbus TCP/IP to facilitate routing. Essentially, Modbus TCP/IP and Modbus RTU are the same except for the ability to run on Ethernet with the TCP interface.
