Connect any RS-232/422/485 serial device to ControlLogix® or CompactLogix® controllers with an EtherNet/IP interface.

The Linking Device performs intelligent protocol conversion. It presents serial data to the Logix PLC as easily processed I/O data. This offloads additional calculations from your Logix PLC.

Convert Almost Any Type of Serial Protocol
The device converts almost any serial protocol. Supported protocols include Modbus RTU, DF1, and ASCII. It also handles proprietary Request/Response or Produce/Consume protocols.

Seamless Integration with Studio 5000
Studio 5000® Logix Designer integration makes everything easily accessible. You can manage the serial network configuration directly within Studio 5000. No extra third-party software, licenses, or programming are required.

Connect, Configure, Done
Configure devices using a Custom Add-On Profile for Studio 5000 Logix Designer. This generates dynamic data structures for each connected device. No ladder logic files are needed. It also supports the automatic generation of structured Studio 5000 controller tags. This eliminates the need to create alias tags manually.
