GE Fanuc IC200DBI001 VersaMax DeviceNet Network Interface Unit (Slave NIU)
1. Product Overview
The IC200DBI001 is the DeviceNet Network Interface Unit (NIU) in the GE Fanuc (now Emerson Automation Solutions) VersaMax distributed I/O system. It is a DeviceNet slave (Group 2 Only Server). Installed in slot 0 of a VersaMax I/O station, it bridges the local I/O bus to the DeviceNet network: uplink via a 5-pin DeviceNet connector to a DeviceNet master (Scanner), downlink managing up to 8 VersaMax discrete/analog I/O modules per station.
DeviceNet supports multimaster, peer-to-peer and master/slave communication structures with broadcasting. Each NIU station occupies a unique node address (0–63) on the bus; node address and baud rate (125/250/500 Kbps) are set via rotary switches on top of the module. Data exchange supports cyclic I/O messaging (Change-Of-State and Polling) and acyclic explicit messaging.
A single DeviceNet network connects up to 64 nodes without bridging or routing. The NIU handles up to 128 bytes of input and 128 bytes of output data per scan.

7. FAQ
Q1: What is the IC200DBI001?
A: The IC200DBI001 is the VersaMax DeviceNet Network Interface Unit (NIU), a DeviceNet slave that bridges a local VersaMax I/O station (up to 8 I/O modules) to the DeviceNet network, remotely read/written by a DeviceNet master Scanner. It provides no I/O points itself and must be paired with discrete/analog I/O modules.
Q2: What baud rates are supported? What is the maximum cable length?
A: 125 Kbps, 250 Kbps and 500 Kbps, selected by top switches. Approx. max bus length: 500 m at 125K, 250 m at 250K, 100 m at 500K. All nodes on the same network must use the same baud rate.
Q3: How many I/O modules can one station support?
A: Each IC200DBI001 NIU station supports up to 8 VersaMax I/O modules, with 128 bytes input and 128 bytes output data capacity. Actual I/O points depend on module density.
Q4: How is the node address set? Which addresses are allowed?
A: Node address range is 0–63, set via rotary switches on top of the module. Each node must have a unique address on the same DeviceNet network.
Q5: Does it require external power?
A: The NIU draws backplane power (5V/160mA, 3.3V/10mA), but the I/O station must have a VersaMax power supply module (e.g. IC200PWR series) to power the I/O modules and NIU. DeviceNet bus power is supplied separately by the network trunk.
Q6: How does it differ from other VersaMax NIUs?
A: IC200DBI001 is the DeviceNet interface; other NIUs include IC200EBI001 (Ethernet TCP/IP), IC200PBI001 (Profibus-DP), IC200GBI001 (Genius) and IC200PNS001 (PROFINET). Choose the one matching the network supported by your upper-level master/controller. Please email us to confirm compatibility.
