FAQ

• Q1: What type of redundancy is supported in the PM866K02 processor unit?
  A1: The PM866K02 supports full CPU redundancy including CPU, CEX-Bus, communication interfaces, and S800 I/O modules for higher system availability.

• Q2: How are the Ethernet ports configured for redundancy?
  A2: The controller includes two built-in Ethernet ports (CN1, CN2) that support redundant communication to ensure uninterrupted network connectivity.

• Q3: Can the PM866K02 be mounted without an enclosure?
  A3: Yes, it has IP20 protection and can be mounted on a DIN rail using the slide & lock mechanism without requiring an additional enclosure.

• Q4: What is the purpose of COM3 and COM4 serial ports?
  A4: COM3 is an RS-232C port with modem control signals for standard serial communication. COM4 is an isolated port used exclusively for configuration tools.

• Q5: How is hardware identity managed for each CPU?
  A5: Each baseplate has a unique Ethernet address attached, providing every CPU with a distinct hardware identity.

• Q6: Which programming tool is compatible with the PM866K02?
  A6: The controller is fully compatible with the 800xA Control Builder software for configuration and management.

• Q7: Are the communication ports compliant with industrial standards?
  A7: Yes, the CPU is designed to support industry-standard protocols including Ethernet and PROFIBUS DP.

• Q8: What measures are in place for power or memory backup?
  A8: Each CPU is equipped with a memory backup battery (4943013-6) to maintain memory during power interruptions.
