Configured for ControlNet to Fieldbus protocol conversion in industrial communication networks, the Allen-Bradley 1788-CN2FF (1788-CN2FF Linking Device) provides direct communication interface conversion between control network infrastructure and field-level devices.

Model Identification

The 1788-CN2FF is a DIN-rail mounted linking device designed to connect ControlNet communication systems with Fieldbus networks. The unit operates with an 11-30 VDC supply range and provides physical interface conversion through 9-pin SUB-D connectors.

Hardware Specifications

Industrial Network Communication Interface

The 1788-CN2FF supports communication architecture conversion between ControlNet and Fieldbus systems. The module manages protocol exchange between the ControlNet controller environment and connected field devices through dedicated communication channels.

The Allen-Bradley industrial control platform uses deterministic network structures for controller-to-I/O communication. The linking device allows Fieldbus instruments and devices to exchange process information with ControlNet-based control systems without direct modification of the controller network architecture.
