1-Port Modbus Hardened Serial Server

Easily link a serial Modbus device to a TCP Modbus device in harsh environments.

Price: $384.80



5 YEAR DoubleDiamond™ Warranty (Standard)

Product Features

  • Provides a gateway between Modbus® TCP and Modbus ASCII or RTU devices.
  • Allows older PLCs and similar devices to talk to newer TCP sensors and meters.
  • Enables you to monitor a serial industrial device from your office.
  • Rugged design for operation in a wide temperature range.
  • Details

  • UL® Listed for use in Class 1 Division 2 hazardous areas.
  • NEMA TS-2 rated for use in transportation applications.
  • Routes Modbus traffic based on Modbus ID, and remaps conflicting Modbus IDs.
  • Offers Modbus messaging priority control, selectable by source or function code.
  • Features a built-in Web server and easy-to-use management software.
  • Can be easily integrated into most Modbus network configurations.
  • Converts ASCII to RTU as well as ASCII or RTU to Modbus TCP.
  • Features a DB9 port and terminal block for serial connections.
  • Equipped with a 10-/100-Mbps port for TCP connectivity.
  • Boasts high throughput with low latency.
  • Slim IP30 enclosure saves you on DIN rail space.
  • Includes a DIN mounting clip and spring.

  • Easily integrate an older serial Modbus device into your Ethernet Modbus network. This rugged serial server gives you a simple way to migrate to an Ethernet-based industrial control system—without having to replace the older Modbus equipment you've already invested in.

    Translating older and newer protocols, the 1-Port Modbus Hardened Serial Server converts mismatched serial baud rates and settings, enabling the serial Modbus device to become a node on your Ethernet network. Older PLCs can then talk to newer sensors, meters, scales, and other industrial monitoring and automation instruments.

    Configuration can be done through a direct serial connection or via the network, so you can improve productivity and cut down on the amount of time required to troubleshoot a serial device on a factory floor or in a remote location. Configure devices, upgrade firmware, and more—all this from the comfort of your office.

    A simple-to-install, user-friendly software application enables programming. No time-consuming setup is required. The software also features Modbus messaging priority control and allows management through multiple TCP/IP client sessions. The serial server can be configured for TCP client or server operation.

    A built-in traffic monitor provides instant verification of a successful installation, and you can view the serial server's operational status in real time.

    The 1-Port Modbus Hardened Serial Server has a standard DB9 serial port for RS-232 device connections and a removable terminal block for an RS-422 or RS-485 device connection. It also has an autodetecting 10BASE-T/100BASE-TX port for the Ethernet network connection.

    Either device on either side can be a Modbus master or slave, customizable to your application. A serial master can be configured to control an IP slave, for instance. Also, a serial slave device can be accessed over a LAN or WAN by up to 16 simultaneous Modbus TCP masters.
