ABB’s current CI930F documentation lists the 3BDH001010R0002 article number for its current configuration, while your supplied 3BDH001010R0005 is identified by multiple industrial references as CI930F. This is an important procurement distinction: the R0005 suffix should be matched exactly to the installed hardware and documentation rather than automatically assumed identical to R0002.
Application Scenarios & Pain Points
PROFIBUS faults are often network faults masquerading as controller or I/O failures. When several slaves disappear together, replacing individual field modules rarely fixes the underlying problem.
- ABB Freelance / AC 900F: CI930F serves as the PROFIBUS DP master interface connected to the AC 900F controller. ABB documents it specifically for AC 900F controllers.
- Redundant PROFIBUS networks: The two D-Sub interfaces provide Line A and Line B connections for PROFIBUS line redundancy.
- Process instrumentation: Suitable for connecting PROFIBUS DP field devices into the Freelance control environment.
- Legacy DCS maintenance: Particularly useful when an existing AC 900F installation remains in service and the communication module has become a critical spare.
Field note: If both PROFIBUS lines show trouble simultaneously, check the CI930F supply, controller communication status, and connector seating before replacing the module. One loose connector can create a surprisingly convincing “dead module” symptom.
Brief Field Case
A typical maintenance failure looks like this: several PROFIBUS slaves disappear from the controller simultaneously, while their local indicators remain powered. The technician initially suspects the field devices; checking the common PROFIBUS path instead reveals a connector or master-interface problem. With CI930F, checking Line A, Line B, controller status, and module diagnostics together gives a much faster fault boundary.

The Engineer’s Guide: Field Pitfalls to Avoid
WARNING 1 — R0005 versus R0002 is not a cosmetic detail.
ABB’s current hardware selector identifies as 3BDH001010R0002, while your requested unit is 3BDH001010R0005. Independent industrial references identify R0005 as , but the revision relationship is not sufficiently documented to call the two automatically interchangeable.
How to avoid it: Photograph the original label and verify the exact article number, hardware revision, controller type, and Freelance software version before substitution.
WARNING 2 — Do not assume every PROFIBUS master is a substitute.
CI773F also provides PROFIBUS DP master functionality, but ABB documents separately and specifically identifies PROFIBUS line redundancy as a feature.
How to avoid it: Determine whether the installed network actually uses redundant Line A/Line B architecture before considering CI773F or another PROFIBUS interface.
WARNING 3 — Check the PROFIBUS physical layer before condemning the master.
A communication module can be healthy while the network has a termination, shielding, connector, cable, or slave-address problem.
How to avoid it: Check:
- PROFIBUS termination status
- Cable shielding and grounding
- D-Sub connector condition
- Line A / Line B continuity
- Slave addresses
- Bus diagnostics
- Controller configuration
- Communication status LEDs
Do not repeatedly cycle a healthy master while a faulty segment remains connected.
Frequently Asked Questions (FAQ)
What is ABB 3BDH001010R0005?
3BDH001010R0005 is an ABB PROFIBUS DP master communication interface used in the AC 900F controller environment. The documented function supports DP-V0/DP-V1 communication at 9.6 kbit/s to 12 Mbit/s and provides two PROFIBUS connections for line redundancy.
Is compatible with ABB AC 900F?
Yes. ABB’s current hardware documentation explicitly states that is intended for use with AC 900F controllers.
Do not extend that statement to every ABB controller platform. The controller generation and installed Freelance configuration still need to be verified.
What PROFIBUS protocols does support?
The documented supports PROFIBUS DP-V0 and DP-V1, with transmission speeds from 9.6 kbit/s to 12 Mbit/s.
This makes it suitable for conventional cyclic DP data exchange as well as DP-V1 services where supported by the connected field devices and configuration.
Does support PROFIBUS redundancy?
Yes. ABB identifies PROFIBUS line redundancy as a feature, using separate Line A and Line B connections.
That is one of the main reasons not to casually replace it with an older or simpler PROFIBUS interface.
What is the difference between R0005 and R0002?
This is the key procurement question for your specific part. ABB’s current public hardware selector lists as 3BDH001010R0002, while industrial references identify 3BDH001010R0005 as .
The safest position is:
Do not assume R0002 and R0005 are drop-in equivalents until the installed system documentation and hardware revision are checked.
For a live DCS, exact suffix matching is preferable.
Can be hot-swapped?
ABB’s current documentation lists Hot Swap: Yes.
That does not mean every installation should be hot-swapped without a maintenance procedure. Confirm the installed controller configuration, redundancy architecture, and site work instructions first. A communication-interface replacement can affect multiple field devices simultaneously.
What power does require?
ABB documents approximately 80 mA at 24 V through the CPU module’s 24 V terminal and approximately 1.8 W power dissipation.
If the replacement does not power correctly, check the CPU-side supply and module seating before assuming the itself has failed.
How should a refurbished be tested?
For a DCS spare, I would ask for evidence of more than a power-up:
- Confirm / 3BDH001010R0005 identification.
- Record hardware revision.
- Inspect both 9-pin PROFIBUS connectors.
- Verify 24 V supply and module current.
- Test Line A communication.
- Test Line B communication where applicable.
- Verify DP master operation.
- Connect representative PROFIBUS slaves.
- Confirm diagnostics and status indications.
- Document the test results and test date.
A module that merely illuminates its power LED has not demonstrated PROFIBUS master functionality.
What should I request before purchasing this ABB ?
Request a photograph of the , showing 3BDH001010R0005, plus the hardware revision and connector condition. For refurbished stock, ask specifically whether both PROFIBUS interfaces have been functionally tested.
For a critical AC 900F spare, also provide the installed controller model and current module article number. That makes it possible to distinguish a true replacement from a visually similar revision.
