ABB 35FB90 System 800xA Multiprocessor Control Module
The ABB 35FB90, also cataloged as the 35FB90 Multiprocessor Control Module, operates as a dedicated hardware component for real-time processing and direct physical/electrical execution within ABB Ability System 800xA platforms. The module interfaces discrete logic channels and field signals across integrated 16 digital inputs and 16 digital outputs, executing deterministic automation programs while communicating over Ethernet and RS-485 network channels.

Backplane Bus Communication Velocity and Deterministic Networking
The 35FB90 multiprocessor module mounts directly into System 800xA rack assemblies, maintaining high backplane bus communication velocity across expanded controller sub-racks. Internal high-speed processing logic manages digital I/O density scaling without introducing scan latencies into closed-loop control routines. Onboard flash memory maintains full firmware flash compatibility to support deterministic network clock execution across Profinet and EtherNet/IP bus structures.
Frequently Asked Questions
Q: How does the 35FB90 module draw internal logic power from the rack assembly?
A: The card connects directly to the chassis backplane power rail, utilizing an external 24 VDC field power source to drive internal processing circuits and digital I/O channels.
Q: Does the 35FB90 hardware support online replacement while the system rack is energized?
A: Yes, the module supports hot-swappable installation into compatible rack slots, provided field power to the digital I/O terminal block is isolated prior to module extraction.
Q: How are communication protocols configured on the onboard Ethernet and RS-485 interfaces?
A: Channel parameters and network baud rates are established during system initialization via software configuration downloads stored directly in the 256 KB onboard memory.
Field Installation Guidelines
First, turn off all 24 VDC power sources feeding the target rack baseplate and isolate field input/output circuits prior to installing the 35FB90 module. Next, align the module edge connectors with the card guides, pushing the unit steadily until the backplane bus plug seats completely into the chassis receptacle. Then, strip signal conductors to the recommended length and tighten screw terminals on the front connector block to ensure low-resistance electrical contact. Finally, route Ethernet network cables separately from high-voltage AC motor lines, grounding cable shields at a single chassis grounding terminal to prevent electrical noise interference.
