Fast copying I/O data (Big data support)

The Linking Device primary function is with the fast transfer of large I/O data between the two networks. This offloads your Logix PLC from working with additional calculations.

The Linking Device acts as a slave (adapter) on EtherNet/IP and as a powerful client (master), on the Modbus-TCP network, handling up to 8 KB of I/O data. The data transmission between the two networks is completely transparent.

Minimise costs when connecting Modbus-TCP networks/devices 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 which dynamically generates data structures based on the configuration. No ladder logic files (add-on instructions) needed.

Furthermore, it also supports the 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 Modbus-TCP network configuration. No extra 3rd-party software or licenses needed.
