ABB CI570 3BSE001440R1 | MasterFieldbus Controller for Advant OCS / AC 400

Description

Key Technical Specifications

Product Introduction

If you have ever walked into an old ABB Advant cabinet and found a blinking comms module with no documentation, you already know why the CI570 matters. It is not a CPU. It is not an analog card. It is the communication gateway that lets an Advant Controller 410/450 talk to remote I/O, drives, and field devices over MasterFieldbus. When this module dies, the controller may still run, but half the plant stops reporting.Engineers keep this part in spares because it is specific. The 2 Mbit/s MasterFieldbus link, the twisted-pair/coax/fiber options, and the ability to duplicate cables and modems made it practical for real process plants. It is compact, runs on 24 V DC, and slots into the Advant/AC 400 architecture without custom brackets. The downside: it is legacy hardware now. Surplus units vary in condition, and some online descriptions mix it up with CI854, CI571, or even analog I/O modules. Do not buy on a title alone.

Quality SOP & Tech Pitfalls

The Lab Report (SOP)

1. Visual inspection: check the ABB label, part number 3BSE001440R1, revision, serial number, and housing condition.
2. Counterfeit/swap check: compare dimensions (234 × 112.5 × 27 mm), connector layout, and mounting hardware against known CI570 photos.
3. Connector inspection: look for bent pins, corrosion, or loose DB/fieldbus connectors.
4. Live test on test rack: apply 24 V DC, verify LED power and comms indicators, and confirm backplane recognition.
5. Insulation and continuity checks: verify supply pins, bus lines, and chassis ground with a multimeter (Fluke 115 or equivalent).
6. Firmware/revision logging: record any visible firmware or hardware revision codes.
7. Anti-static packing: seal in ESD bag with label photos and test notes.

The Engineer’s Warning (Pitfalls)

• Protocol confusion kills schedules. Some sellers label this CI570 as a Profibus DP, Modbus, or FOUNDATION Fieldbus H1 device. The documented CI570 belongs to the Advant MasterFieldbus/Advant Fieldbus 100 family. If your system runs CI854 Profibus or FF H1 segments, this may not be the correct card.
• Bus termination and media matter. MasterFieldbus at 2 Mbit/s works up to about 25 m on twisted pair without modems. Longer runs need modems, coax, or fiber. Swap the module but leave the wrong terminator or cable type in place, and the segment stays down.
• I once watched a plant sit on a “bad CI570” for two days. The module was fine. The real problem was a corroded fieldbus connector and a missing terminator on the last node. Always check the cable plant before blaming the card.

Installation & Configuration Guide

1. Pre-Installation ⚠️
   • Notify operations and place the relevant controller segment in a safe state.
   • Shut down 24 V DC to the rack if hot-swap is not confirmed for your configuration.
   • Photograph the existing module, bus connectors, address settings, and cable labels.
   • Record the bus media type: twisted pair, coax, or fiber.
2. Removal
   • Label every cable before disconnecting.
   • Release DIN-rail clips or rack fasteners carefully.
   • Pull the module straight out; do not rock it sideways.
   • Inspect the backplane connector for bent pins before installing the replacement.
3. Installation
   • Copy all switch, jumper, and address settings from the old module. This prevents most startup failures.
   • Seat the new CI570 firmly into the rack/DIN-rail position.
   • Reconnect bus cables exactly as labeled.
   • Verify that the correct terminators are installed at the required segment ends.
4. Power-On & Testing
   • Restore 24 V DC.
   • Check power and communication LEDs against the ABB manual.
   • Verify controller recognition of the CI570 in the Advant OCS/AC 400 configuration.
   • Confirm communication with S800 I/O, drives, or remote units.
   • Monitor the segment for at least one full production cycle before closing the work order.

Frequently Asked Questions (FAQ)

Q: Is the CI570 3BSE001440R1 a CPU module?
No. It is a communication interface module for the Advant Controller 410/450 and AC 400 family. The CPU is a separate module.Q: Can I use it for Profibus DP or FOUNDATION Fieldbus H1?
Not reliably. Some third-party listings claim Profibus DP, Modbus, or FF H1 support, but the documented CI570 is a MasterFieldbus/Advant Fieldbus 100 controller. If your system uses CI854 Profibus or FF H1 segments, you probably need a different module.Q: Can I hot-swap it?
Advant Fieldbus 100 supports reconnecting remote units without disturbing the rest of the bus, but whether the CI570 itself can be hot-swapped depends on the controller, rack, and configuration. If you are unsure, power down the 24 V supply first.Q: What bus speed does it run?
MasterFieldbus typically runs at 2 Mbit/s. A 375 kbit/s mode is referenced for certain devices such as MasterPiece 90. Verify cable length and modem requirements before changing speeds.Q: How long is the bus cable allowed to be?
Up to about 25 m on twisted pair without modems. Longer distances require modems, coaxial cable, or fiber optic links.Q: Is this part still produced by ABB?
It is considered legacy. Most available units are surplus, new-old-stock, or refurbished. Always request a label photo and revision code.Q: What warranty should I expect?
Surplus sellers vary. A 12-month warranty on conformity and workmanship is common for reputable suppliers, but it must be confirmed on the sales invoice. Damage from incorrect wiring, bus termination errors, or environmental abuse is normally excluded.
