Product Introduction
The ABB SM810K01 3BSE030928R1 is a high-integrity safety CPU module designed for the AC800M platform. It serves as the central safety controller for processes requiring SIL3 certification, executing safety logic with deterministic timing and fault tolerance.This module features 32 MB of RAM and supports full redundant operation for maximum availability. It integrates with the S800 I/O system via the redundant CEX bus, providing a complete safety automation solution. (Always verify the exact firmware version required for your safety application, as safety-rated CPUs have strict compatibility requirements).
Installation & Configuration Guide
Preparation (10 min)
Ensure the AC800M chassis is de-energized. Gather the module mounting hardware and ESD protection. Review the system’s safety architecture documentation to confirm the correct slot assignment.Removal (5–10 min)
Disconnect all communication cables from the front panel. Release the module locking mechanism. Slide the SM810K01 3BSE030928R1 straight out of the backplane. Inspect the CEX bus connectors for damage.Installation (10 min)
Align the new module with the chassis guides. Push firmly until the backplane connector seats fully. Engage the locking mechanism. Reconnect all redundant CEX bus cables in the correct sequence.Power-On & Test (10 min)
Restore power to the chassis. Monitor the module status LEDs for normal boot sequence. Use the engineering tool to verify the safety CPU is recognized and communicating. Run the built-in self-test to confirm SIL compliance.
Troubleshooting Quick Reference
- Module not powering up: Verify chassis power supply is within spec. Check the backplane power pins for continuity.
- Redundancy sync failure: Ensure both CPUs are running identical firmware. Check the CEX bus cable connections for proper termination.
- Safety fault LED lit: Consult the AC800M safety manual for specific fault codes. This may indicate an internal diagnostic failure or I/O mismatch.
- Communication loss: Verify the CEX bus configuration in the engineering tool. Check for excessive cable length or noise interference.
- Firmware mismatch: Safety CPUs require exact firmware matching. Do not mix revisions in a redundant pair.
Dimensions, Mounting & Wiring Notes
- Size: Standard AC800M module footprint
- Mounting: DIN rail or backplane slot with front-panel retention
- Wiring: Dual CEX bus connectors for redundant I/O communication. Use shielded cables for noise immunity.
FAQ
Is this module SIL3 certified?
Yes. The SM810K01 3BSE030928R1 is certified for SIL3 safety applications per IEC 61508. Always refer to the current safety manual for the exact certification scope.Can I use this in a non-redundant system?
Yes. The module operates in both standalone and redundant configurations. Redundancy is configured via software and hardware setup.What firmware version do I need?
Safety applications require specific firmware versions. Check your existing system or consult the ABB safety compatibility matrix before ordering.Do you test safety functions before shipping?
We verify basic hardware functionality and communication. Full SIL validation must be performed in your application environment per your safety integrity requirements.Is this compatible with S800 I/O?
Yes. The SM810K01 communicates with S800 I/O modules via the redundant CEX bus. Verify I/O module compatibility in the AC800M hardware manual.Can I hot-swap this module?
No. Safety CPU modules must be replaced during a controlled shutdown. Hot-swapping is not supported for safety-rated controllers.
