EtherNet/IP to Modbus TCP/IP to OPC UA Server Gateway
PLX32-EIP-MBTCP-UA
Need to get data from your EtherNet/IP™ or Modbus® TCP/IP-based devices to your OPC UA clients to be analyzed so you can reduce your operating costs or increase your production?
ProSoft Technology’s EtherNet/IP to Modbus TCP/IP to OPC UA Server communication gateway allows high-speed tri-directional data transfers between EtherNet/IP PACs and Modbus TCP/IP devices, while also providing an OPC UA Server connection.
The Modbus TCP/IP driver features multiple, simultaneous client and server connections for faster data transmission. For simplified integration and reduced commissioning time for Rockwell Automation® EtherNet/IP-enabled PACs, an EDS AOP is provided.
The highly reliable and secure OPC UA Server supports 10 simultaneous OPC UA sessions that provide access to EtherNet/IP and Modbus TCP/IP data from the respective networks.

Features and Benefits
- Two separate Ethernet ports allow EtherNet/IP and Modbus TCP/IP to reside on a different subnet than the OPC UA Server.
- All three protocols operate independently and simultaneously while accessing common process data.
- Data prioritization: Multiple EtherNet/IP I/O connections allow for different RPIs for status and/or control data.
- Includes an embedded EDS Add-On Profile, allowing for simplified integration and reduced commissioning time.
- Gateway includes an SD card slot (SD card optional) for storing configuration files. This can be used for disaster recovery.
