FAQ – PM865K02

Q1: What sets the PM865K02 apart from PM865K01?
A1: The PM865K02 includes the redundancy kit—optical module and base hardware—ready for dual‑CPU deployment without additional purchases.

Q2: Can I deploy the PM865K02 in a single CPU system if needed?
A2: Yes—while pre‑equipped for redundancy, it can operate as a standalone CPU within the AC 800M system.

Q3: Are there real-time benefits to using PM865K02?
A3: Yes—its cycle time is under 1 ms, which supports highly responsive control loops and quick decision-making.

Q4: Does it support modern industrial networks?
A4: It does—with built-in support for Ethernet/IP, PROFIBUS, Modbus, and ControlNet.

Q5: Will it work with existing ABB S800 I/O cards?
A5: Yes—the design ensures full backward and forward compatibility across ABB’s control ecosystem.

Q6: How does the physical installation work?
A6: The module mounts on standard DIN rail in control cabinets and follows a compact 186 × 59 × 123 mm footprint.

Q7: Is the PM865K02 built for tough environments?
A7: Definitely—certified for industrial use, with compliance to ATEX and other standards.

Q8: What kind of power backup does it accept?
A8: It operates on 24 V DC and supports redundant power inputs for uninterrupted operation.

Q9: Does the module weigh significantly more than other CPUs?
A9: At 0.70 kg, it’s slightly heavier due to redundancy components but still aligns with series norms.

Q10: Is software configuration needed for redundancy?
A10: Yes—but the hardware is ready; you only need to configure redundancy logic in engineering tools during setup.
