PLX82-MBTCP-PNC Modbus TCP/IP to PROFINET Controller Gateway Protocol Converter Product Photo

Modbus® TCP/IP to PROFINET Controller Gateway


The Modbus® TCP/IP to PROFINET Controller Gateway allows you to connect two giants of industrial automation through secure, high-speed communications. The gateway provides Modbus TCP/IP-based controllers the ability to control up to 36 PROFINET RT devices such as field I/O, drives, HMIs, and controllers.

The PLX82-MBTCP-PNC gateways are stand-alone DIN-rail mounted units that provide two Ethernet ports for communications, remote configuration, and diagnostics. The onboard SD Card slot (SD card optional) is used for storing configuration files that can be used for recovery, transferring the configuration to another gateway, or general configuration backup.
