Fully compliant with Modbus/TCP, the Modbus Gateway Serial Device Server offers a convenient solution to connect existing devices or controllers running Modbus serial protocol (Modbus/ASCII or Modbus/RTU) to an Ethernet network. Featuring built-in Ethernet switches, Advantech’s Modbus Gateways provide transparent connectivity between Modbus/ASCII, Modbus/RTU serial devices and Ethernet-based Modbus/TCP equipment. They are able to fulfill flexible installation and web browser configuration requirements for remote monitoring applications. Our Modbus Gateway products provide a simple and cost-effective way to bring the advantage of remote management and data accessibility to devices that cannot connect to a network, with easily converting Modbus/ASCII and Modbus/RTU to Modbus/TCP. And furthermore, for EKI-1221D/1222D, cascading connections support Ethernet auto-bypass to prevent accidental power failure in the event one of the Modbus Gateways unexpectedly shuts down.
