GE IC670PBI001 Profibus Bus Interface Unit | Series 90-70

GE IC670PBI001 Profibus Bus Interface Unit – Series 90-70 PLC

When a Profibus network segment loses its bus interface, the consequences cascade fast: field devices go silent, process variables disappear from the controller, and operators are left flying blind. In a continuous manufacturing environment — a paper mill mid-run, a water treatment plant managing dosing cycles, or an automotive body shop coordinating robot cells — even a 15-minute unplanned outage translates directly into scrap, safety incidents, and contractual penalties. The IC670PBI001 is the component that keeps that from happening.

Within GE’s Series 90-70 architecture, the IC670PBI001 occupies a specific and non-substitutable role: it is the dedicated Profibus DP bus interface unit that bridges the Series 90-70 backplane to a Profibus DP field network. Unlike generic communication modules, this unit was engineered alongside the Series 90-70 I/O family, meaning its timing, addressing, and diagnostic behavior are tightly coupled to the GE PACSystems and Series 90-70 CPU firmware. Profibus DP remains one of the most widely deployed fieldbus protocols in European and Asian heavy industry, and the IC670PBI001 continues to serve as a critical spare and replacement component across tens of thousands of installed systems globally.

Key Features & Benefits

• Auto Baud Rate Detection (9.6 kbps–12 Mbps) — Eliminates manual DIP-switch configuration during commissioning, reducing setup time by up to 60% compared to fixed-rate alternatives.
• Hot-Swap Compatible with Series 90-70 Backplane — Allows module replacement without full rack power-down in supported configurations, minimizing process interruption during maintenance windows.
• Profibus DP Class 1 Master/Slave Support — Enables both master (controller-side) and slave (I/O-side) topologies within a single module type, providing deployment flexibility across mixed-architecture sites.
• Integrated Diagnostic Reporting via GE Logicmaster/Proficy — Bus faults, slave dropouts, and CRC errors are surfaced directly in the PLC fault table, meeting IEC 61131-3 diagnostic transparency requirements.
• Supports Up to 244 Bytes Input / 244 Bytes Output per Slave — Accommodates high-density I/O slaves such as valve manifolds and multi-axis drive interfaces without segmentation.
• Direct Replacement for Aging Series 90-70 Installations — Drop-in compatible with existing baseplates and wiring; no firmware upgrade required for most Series 90-70 CPU revisions, protecting existing capital investment.

Industry & Equipment Applications

• Automotive Manufacturing — Body-in-white welding lines, paint shop conveyor control, and press transfer systems where Profibus DP coordinates robot controllers and vision systems.
• Pulp & Paper — Stock preparation, headbox control, and dryer section drives where continuous process data from distributed sensors must reach the DCS/PLC without latency.
• Water & Wastewater Treatment — Pump station automation, dosing control, and SCADA-connected remote I/O panels operating under EN 50170 fieldbus standards.
• Oil & Gas Upstream/Midstream — Wellhead control panels and pipeline compressor stations using Series 90-70 PLCs with Profibus-connected pressure transmitters and valve positioners.
• Food & Beverage Processing — Filling lines, CIP (clean-in-place) systems, and packaging machinery where hygienic-area I/O slaves communicate over Profibus DP to a central controller.
• Power Generation & Utilities — Turbine auxiliary systems, switchgear control, and substation automation panels where the Series 90-70 platform remains the installed standard.

Our Quality Assurance Process

1. Visual & Physical Inspection — Each unit is examined for board damage, connector integrity, label legibility, and correct revision markings against GE’s published hardware revision history.
2. Functional Power-On Test — Module is seated in a Series 90-70 test rack and powered; LED status indicators and backplane communication are verified against expected behavior per GFK-1504.
3. Profibus Communication Verification — A live Profibus DP segment with known-good slave devices is used to confirm master/slave handshake, baud rate auto-detection, and cyclic data exchange.
4. Final Documentation & Packaging — Unit is cleaned, anti-static bagged, and boxed with foam protection. Shipment includes test report, photos of actual unit, and available traceability documentation.

Frequently Asked Questions

Q: Is the GE IC670PBI001 compatible with PACSystems RX7i controllers?
A: The IC670PBI001 is a Series 90-70 module and is designed for Series 90-70 baseplates. PACSystems RX7i uses a different backplane architecture (IC698 series). While RX7i racks can accept some Series 90-70 modules in compatibility mode, Profibus interface modules are not among the supported cross-compatible types. For RX7i Profibus connectivity, the IC698PBM001 is the appropriate module. Contact us to confirm your specific configuration before ordering.

Q: What is the difference between IC670PBI001 and IC670PBI001B, and can I use them interchangeably?
A: The “B” suffix denotes a hardware revision update. In most Series 90-70 installations running firmware version 6.0 or later, the two revisions are functionally interchangeable. However, if your system runs an earlier CPU firmware revision, we recommend verifying against GE’s compatibility matrix (GFK-1504 appendix) or contacting our technical team before substituting revisions.

Q: Can the IC670PBI001 be used as a Profibus DP slave to connect a Series 90-70 rack to an upstream Siemens S7 master?
A: Yes. The IC670PBI001 supports both DP master and DP slave operating modes. When configured as a slave, the Series 90-70 rack appears as a standard Profibus DP slave device to any Class 1 master, including Siemens S7-300/400 and S7-1500 with CP 342-5 or CM 1542-5 communication processors. GSD file configuration is required on the master side.
