Convert almost any type of serial protocol

The Linking Device is capable of converting almost any type of serial protocol such as Modbus RTU, DF1, ASCII, or any other type of proprietary; Request/Response or Produce/Consume protocol.

It performs intelligent protocol conversion and presents the serial data to the Logix PLC as easily processed I/O data. This offloads your Logix PLC from working with additional calculations. Connect any RS-232/422/485 serial device to ControlLogix® or CompactLogix® controllers with an EtherNet/IP interface.


Connect, Configure, Done!

EtherNet/IP Linking Devices are configured using a Custom Add On Profile for Studio 5000 Logix Designer. This dynamically generates data structures for each device connected. No ladder logic files (add-on instructions) needed.

Furthermore, it also supports automatic generation of named and structured Studio 5000 controller tags, which eliminates the need to create alias tags

Seamless integration with Studio 5000

With its unique Studio 5000® Logix designer integration, everything is accessible from within Studio 5000, including then serial network configuration. No extra 3rd-party software, licenses or programming required.
