Frequently Asked Questions

Q: What is the difference between PM862 and PM862K01?

A: PM862K01 (3BSE076940R1) is the standard non-redundant version. The “K01” suffix indicates specific factory configuration – functionality is identical to base PM862.

Q: Can I upgrade this unit later for redundancy?

A: Yes. The PM862K01 supports redundancy when paired with a second CPU, redundant CEX bus modules, and S800 I/O clusters. Maximum switchover time is 10 ms.

Q: What tools do I need to configure this controller?

A: Use Compact Control Builder 6.0.0-1 or higher with System 800xA 6.0.2+. Connect via COM4 (isolated service port) or Ethernet.

Q: Is the CompactFlash card included?

A: No. The interface is provided, but card is sold separately. Use industrial-grade CompactFlash for reliability.

Q: What is the warranty period?

A: 12 months from delivery against manufacturing defects. We ship worldwide via FedEx, UPS, or DHL – fully tracked.

Q: How many I/O modules can I connect?

A: Up to 96 modules on Modulebus with single CPU, or 84 modules in redundant configuration. Use optical clusters for long distances.

Q: Does it work in high humidity or corrosive areas?

A: Yes. It handles 5‑95% humidity non‑condensing and meets ISA G3 corrosion resistance – suitable for harsh industrial environments.

Selection Guidance

• Choose PM862K01 for standard applications – upgrade to redundant CPUs later if needed.
• Verify software version: requires System 800xA 6.0.2+.
• For marine use, DNV-GL certification is included – no extra cost.
• Order CompactFlash card separately (not included).
• Need more I/O? Add BC810/BC820 for sectioned CEX-Bus expansion.

Package & Warranty
