PLX31-EIP_MBS

EtherNet/IP to Modbus Serial

PLX31-EIP-MBS

ProSoft Technology’s EtherNet/IP™ to Modbus® Serial communication gateway allows high-speed bi-directional data transfers between EtherNet/IP™ PACs or devices and Modbus®-enabled PACs or devices.

EtherNet/IP™ PACs include Rockwell Automation® ControlLogix® and CompactLogix™, as well as several Schneider Electric® controllers. Modbus® Serial devices are widely used in nearly every industry and include SCADA systems and Power Monitors.

The gateway includes several features that allow for simplified integration, reduced commissioning time and optimized performance

Features and Benefits

  • Data prioritization: Multiple I/O connections allow you to set RPIs for status and/or control data, optimizing Ethernet bandwidth. 
  • Includes an embedded EDS Add-On Profile, allowing for simplified integration and reduced commissioning time. 
  • 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 4000 16-bit registers can be used to exchange large amounts of data.
