The ProSoft Technology PLX32-EIP-MBTCP is an industrial communication gateway enabling bi-directional data transfer between EtherNet/IP and Modbus TCP/IP networks. It bridges devices from manufacturers such as Rockwell Automation and Schneider Electric, supporting their respective PACs without requiring IP address changes on connected devices.
