Magnum DX800 and DX40 Serial Device Routers supplied by Dewar Electronics allow users to integrate existing and new Modbus/RTU and Modbus/ASCII serial devices with newer TCP/IP network devices.

Modbus fieldbus technology allows for serial communications between many devices connected to the same network. For example, Modbus is often used to connect a supervisory computer with a remote terminal unit (RTU) in serial supervisory control and data acquisition (SCADA) systems.

Modbus/TCP, an extension of Modbus/RTU, defines how Modbus/RTU and Modbus/ASCII messages are encoded within and transported over TCP/IP-based networks.

Major features of the MNS-DX Modbus/TCP functionality include:

Simultaneous client and server operation, including support for multiple serial master and slave Modbus devices

Support for both the ASCII and RTU serial protocol variants

Modbus Plus gateway exceptions provide feedback to master devices when network configuration or communication errors occur

There are configurable timeouts on both the client and server side. This provides maximum flexibility for connecting to a wide variety of serial Modbus devices

Combining features of a Serial Device Server, Ethernet Switch and IP Router in a single product, Magnum DX Serial Device Routers deliver secure multi-protocol networking in a compact, rugged package built for heavy-duty industrial sites, substations, and other harsh environments.

Each DX unit serves as a multi-protocol concentration and access point for a fiber-based Ethernet connection to a small site.

Encrypted per-session SSL and IPsec VPN capabilities, along with other industrial firewall and port security features, assure cyber-security protections will extend cost effectively all the way to end-point devices and small facilities.

The DX Serial Device Routers introduce a new concept in industrial networking - the Dynamic Serial Edge. Traditional Serial/IP Ethernet products relegated serial devices to static roles. New requirements such as Cyber Security move serial devices into an integral role in Industrial Networks.
