Serial to Ethernet Converter Applications

Serial to Ethernet converters can be used to transmit serial data over Ethernet and TCP/IP network. The applications of the serial to Ethernet converters include acting as a serial (RS-232, RS-485, RS-422, etc.) to Ethernet converter or a Modbus RTU to Modbus TCP protocol converter; controlling serial devices from remote Modbus TCP software or Modbus RTU master via Ethernet network; making a wide variety of M2M communication applications possible by enabling client access independent of any operating system or proprietary protocol; extending serial communication distance over Ethernet network; and converting conventional serial data network to TCP/IP network. CommFront serial to Ethernet converters are designed for harsh industrial applications and provide a simple yet reliable solution for the following applications:

  • Device Server
  • Serial over Ethernet
  • Modbus Gateway
  • Modbus Protocol Converter
  • Converting Serial Network into TCP/IP
  • Remote Control and Monitor

Application 1: Device Server

The device server makes a wide variety of M2M communication applications possible by enabling client access independent of any operating system or proprietary protocol. In addition, because conventional serial protocol are converted into TCP/IP protocol, the device server can be accessed by remote TCP/IP software and/or control stations. This makes the remote control, management, monitoring, and diagnose possible and, in turn, adds an unprecedented level of intelligence and efficiency to the operation.

Application 2: Serial over Ethernet

Serial to Ethernet converters support one or more channels bi-directional serial to Ethernet conversion which can be used to transmit serial data over Ethernet and TCP/IP network. “Serial over Ethernet” allows you to make use of an existing Ethernet network and extend the distance across a facility or to other facilities all over the globe.

Application 3: Modbus Gateway

Modbus RTU is the most widely used industrial protocol. A typical Modbus system consists of one master and multiple slaves that run over the same single twisted pair cable. CommFront serial to Ethernet converters (e.g. DVS-232-2, DVS-485-2, etc.) can act as a Modbus gateway that encapsulates Modbus packets in standard TCP/IP packets. This enables the filed Modbus devices to connect and communicate over existing Ethernet and fiber networks instantly. In addition, conventional Modbus RTU has a limitation of 247 nodes per network, while Modbus TCP networks can have as many slaves as the physical layer can handle, which often go around 1,024.

Application 4: Modbus Protocol Converter

CommFront serial to Ethernet converters can act as a Modbus protocol converter that encapsulates Modbus packets in standard TCP/IP packets. A Modbus protocol converter allows conventional Modbus RTU master and slave devices that run on twisted-pair cable to run over Ethernet and fiber networks with greater distance and flexibility (e.g. the COM port settings for client and server can be different).

Application 5: Converting Serial Network into TCP/IP

By using serial to Ethernet converters, you can convert existing RS-232/RS-485/RS-422 field devices such as PLC and RTU into TCP/IP devices, which can directly be controlled by the TCP/IP control software. With CommFront’s Serial-TCP software (an advanced serial to TCP/IP bridging software), you can also convert conventional serial control software into TCP/IP software instantly and seamlessly without a need of software modifications. In addition, various serial devices with different COM settings (RFC2217 supported) can be merged into the same TCP/IP network, thus making the entire network conversion fast, easy, and secure.
