GE Fanuc Field Control 1995 User Manual – The Only Factory Spec Source for Your Distributed I/O System

Working with a GE Fanuc Field Control system and guessing at DIP switch settings? That’s a good way to smoke a Bus Interface Unit. You need the OEM documentation, not some aftermarket PDF that skipped half the warnings. This User Manual from 1995 is the real deal – 68 pages of factory-specified procedures for installation, configuration, and diagnostics. No reprints, no fluff, just the same document that came off the GE Fanuc press.

Field Control Distributed I/O: What This Manual Covers

Chapter 1 walks you through the Field Control features and modules – the FIP Bus Interface Unit, terminal blocks, I/O modules, and the hand-held programmer (HHP). Chapter 2 is where the meat is: preinstallation checks, static protection (see page 12 for the exact wrist strap requirements), DIN rail mounting, BIU DIP switch positions, and system wiring guidelines. If you skip the grounding section, you’ll chase noise gremlins for days. Chapter 3 covers operating modes – Idle, Ready, Run – and how communication affects each. Chapter 4 gives you the HHP functions: displaying configuration, forcing I/O data, clearing faults.

68 Pages of Factory Wiring and Configuration Data

You get pin assignments for the FIP bus connectors, power wiring to the BIU, and fuse replacement steps. There’s a full section on configuring I/O modules – discrete inputs, discrete outputs, analog inputs, analog outputs, even output scaling. Each section includes the exact menu structure from the HHP so you don’t have to hunt through a dozen submenus blind. The manual also lists the status data transmitted by the BIU for diagnostics – that’s the stuff you need when a machine randomly faults and the PLC screen says nothing.

Bus Interface Unit DIP Switch Settings – Get Them Right

One wrong DIP switch and your BIU won’t talk to the FIP bus. This manual shows the switch positions and what each one does. No guesswork. It also details how to set the FIP protocol type using the HHP. If you’ve ever tried to configure an empty slot without the manual, you know the HHP throws error codes with zero explanation. Chapter 4 covers reading module configuration and configuring empty slots properly.

Does This Manual Cover the Hand-Held Programmer?

Yes – Chapter 4 is dedicated to the HHP. It covers display formats (binary, hex, decimal), forcing and unforcing data, displaying and clearing faults. The HHP section includes menu overview and step-by-step for each configuration task. Without this, you’re poking at buttons and hoping. I’ve seen a guy force an output and not remember how to unforce it – that’s a call to engineering after a production halt.

Static Protection and System Grounding – Follow Spec or Replace Modules

Page 18 outlines the static protection procedure. GE Fanuc calls out specific handling requirements – you must ground yourself before touching the BIU or I/O modules. The system grounding section tells you how to bond the DIN rail and terminal blocks. Ignore that and you’ll get intermittent resets that are a nightmare to trace. Unlike generic Electronic Stability Control systems found in some vehicles, the Field Control BIU uses a deterministic FIP bus that demands clean ground references. The Bus Interface Unit functions like an Engine Control Unit but for distributed I/O – same need for correct wiring, same consequence for shortcuts.

This manual cost less than one hour of shop labor. You’ll save that in the first ten minutes of not having to call tech support. Access the Factory Manual and keep it on your bench – you’ll need it.

What type of documents does this manual contain?

It’s a user manual with installation, operation, configuration, and diagnostic procedures for the GE Fanuc Field Control distributed I/O system. Not a service manual – you won’t find component-level repair data.

Does it cover the Series 90-70 PLC requirements?

Yes. Chapter 1 includes a section on Series 90-70 PLC requirements for network configuration and hand-held programmer compatibility.

Are the DIP switch positions clearly shown?

Page 22 has a diagram with the switch positions and descriptions. You can set the BIU to the correct node address and protocol without pulling out a multimeter.

Can I use this manual to troubleshoot a non-communicating BIU?

The diagnostic section in Chapter 3 tells you how to observe the LEDs and interpret status data transmitted by the BIU. If the BIU is in Idle mode and not transitioning to Run, the manual walks through the communication checks. That said, if the BIU has physically failed, this won’t help you fix the board – you’ll need a replacement.
