Technical FAQs

  1. What is the main purpose of the PM866K02?
    It provides redundant processing to maintain continuous control system operation.

  2. Does the unit support automatic failover?
    Yes, switchover between processors is automatic and bumpless.

  3. Can the system continue running if one processor fails?
    The standby processor immediately assumes control.

  4. Is operator intervention required during failover?
    No manual action is required.

  5. Can hardware be replaced while the system is online?
    The redundant design allows replacement of the standby processor during operation.

  6. Is this processor suitable for complex control logic?
    It is designed to handle large and demanding control applications.

  7. How is data consistency maintained?
    Both processors continuously synchronize control data in real time.

  8. Does redundancy affect execution speed?
    Deterministic performance is maintained during normal operation.

  9. Is the PM866K02 compatible with standard AC 800M I/O?
    Yes, it integrates seamlessly with AC 800M I/O architectures.

  10. What types of projects typically specify this unit?
