Description

GE Fanuc IC693NIU004 Ethernet Network Interface Unit (ENIU) for Series 90‑30 PLC System

Product Details

The IC693NIU004 is a single‑slot Ethernet Network Interface Unit (ENIU) for legacy GE Fanuc Series 90‑30 PLC platforms, not a CPU, does not execute user logic program. Origin: USA, EOL discontinued component. It is installed into the CPU slot of Series 90‑30 baseplate, serves as remote I/O drop station over industrial Ethernet via EGD (Ethernet Global Data) protocol. Equipped with built‑in 10/100 Mbps 3‑port Ethernet switch, two RJ45 ports for daisy‑chain topology, one local service port; also includes RS232 / RS485 serial interfaces. Power consumption 7.4W from backplane 5VDC, requires high‑capacity power supply for chassis. Supports SRTP server, EGD producer‑consumer data exchange, SNP communication; handles up to 2048 discrete I/O points, 1268 analog input & 512 analog output channels. Front‑panel multi‑LED status indicators and dedicated Ethernet reset push‑button. Configuration completed via Proficy Machine Edition software. Widely supplied as aftermarket spare‑parts for petrochemical, power‑plant and manufacturing legacy automation retrofits.

Applications

‑ Distributed remote I/O stations over Ethernet for Series 90‑30 PLC systems ‑ Petrochemical plant legacy control system spare‑part replacement ‑ Power‑plant auxiliary control cabinet Ethernet remote‑I/O expansion ‑ Manufacturing production‑line legacy PLC network renovation ‑ Water‑treatment plant distributed automation retrofitting projects ‑ Migration replacement for older IC693NIU001 NIU modules ‑ Industrial sites requiring EGD Ethernet Global Data communication architecture

Key Features

1. Dedicated Ethernet Network Interface Unit for Series 90‑30, functions as remote I/O drop without local user‑logic execution.
2. Integrated 3‑port 10/100Mbps Ethernet switch, supports daisy‑chain wiring for multi‑drop remote‑I/O network layout.
3. Implements EGD producer‑consumer mechanism for high‑speed remote I/O data exchange with master 90‑30 CPU.
4. Supports SRTP, SNP protocols; provides RS232 / RS485 serial auxiliary communication interfaces.
5. Handles maximum 2048 discrete points and large‑capacity analog I/O mapping for distributed stations.
6. Front‑panel diagnostic LED array plus dedicated Ethernet reset push‑button for quick on‑site troubleshooting.
7. Single‑slot chassis mounting, powered by PLC backplane; CE & UL certified, manufactured in USA.
8. EOL obsolete hardware, applied for maintenance and retrofit of existing 90‑30 distributed automation systems.

Main Functions

1. Operates as remote I/O slave drop station, scans local base and expansion‑rack I/O modules on behalf of master Series 90‑30 CPU.
2. Transmits field input signals to master controller and receives output commands from master CPU through EGD Ethernet Global Data protocol.
3. Build distributed I/O network via Ethernet daisy‑chain connection, replacing traditional Genius serial remote‑I/O bus.
4. Supports SRTP and SNP communication for configuration, diagnosis and data access from engineering workstation.
5. Real‑time mapping of large‑scale discrete and analog I/O data between remote station and main controller memory area.
6. Provides hardware status and communication fault indication via front‑panel LED lamps, with independent Ethernet reset button.
7. Accept configuration download from Proficy Machine Edition, stores network parameters inside onboard flash and RAM memory.
8. Cooperates with Series 90‑30 master CPU to complete whole‑set distributed Ethernet‑based PLC control architecture.
