Description

Overview

The IC200DBI001 is a VersaMax Network Interface Unit designed by GE Fanuc Emerson to connect modular VersaMax I/O stations to a DeviceNet field network. It functions as a slave interface, translating rack-based I/O data into DeviceNet-compatible communication for a host controller.

This unit supports distributed control architectures where remote I/O expansion is required over a DeviceNet backbone, ensuring deterministic data exchange between field devices and the master controller.

System Functionality

The module serves as the communication bridge between VersaMax I/O racks and DeviceNet networks.

• Operates as a DeviceNet slave node

• Supports up to 8 I/O modules per station

• Maps process data directly to network I/O image

• Handles cyclic polling and change-of-state communication

• Provides onboard configuration retention during short power interruptions
