This module enables the integration of a GEM80 controller into a Rockwell Logix platform (e.g. ControlLogix or CompactLogix) or Rockwell HMI (e.g. FTView / PanelView) with minimal effort.​

The The module can be configured to either exchange data between a Logix controller and a GEM80 controller at a fixed interval, or as an AB Ethernet PCCC slave and DECNet master allowing a Rockwell SCADA to directly communicate with a GEM80 controller.

The module also provides a range of statistics to help fault find any problem.

A built-in webserver provides detailed diagnostics of system configuration and operation, including the display of GemLan operation and communication statistics, without the need for any additional software.
