Features and Benefits

  • Supports up to 20 simultaneous client & server connections, allowing for faster communication between devices such as HMIs, SCADA systems, power monitors and flow computers, among others.
  • Includes a SD card slot (SD card optional) for storing configuration files. This can be used for disaster recovery.
  • ProSoft Discovery Service: This utility allows your PC to see the gateway and change its default IP address without being on the same subnet.
  • Secure module configuration via module switch (v1.04 and greater).
  • Up to 10,000 16-bit registers can be used to exchange large amounts of data.
