EtherNet/IP to Modbus TCP/IP Communications Gateway

PLX32-EIP-MBTCP

ProSoft Technology’s EtherNet/IP™ to Modbus® TCP/IP communication gateway allows high-speed bi-directional data transfers between Rockwell Automation® PACs and Schneider Electric® PACs. Our Modbus® TCP/IP driver features multiple client and server functionality, for faster data transmission. Two separate Ethernet ports allow each protocol to reside on separate subnets, allowing you to pass data between the two subnets without changing each device’s IP address. In addition, the gateway includes an embedded EDS Add-On Profile, allowing for simplified integration and reduced commissioning time.

A conformal coating option is available for this product.

Features and Benefits

  • Two separate Ethernet ports allow each protocol to reside on separate subnets. This allows you to pass data between the two subnets without changing each device’s IP address to be on the same subnet.
  • Data prioritization: Multiple I/O connections allow you to set RPIs for status and/or control data.
  • Includes an embedded EDS Add-On Profile, allowing for simplified integration and reduced commissioning time.
  • Gateway includes a SD card slot (SD card optional) for storing configuration files. This can be used for disaster recovery.
  • Secure module configuration via module switch (v1.04 and greater).
  • Up to 4000 16-bit registers can be used to exchange large amounts of data.
