Frequently Asked Questions (FAQ)
What is the core difference between 5466-1035 and CPU P1020?A: The CPU P1020 uses a dual-core SOC processor with four times the performance of the MPC5200. It supports 5 CAN ports, Gigabit Ethernet, and includes security passwords, Achilles certification, and SSH encryption.The 5466-1035 is a basic CPU without security features, suitable for legacy systems or non‑safety‑critical applications. For new safety systems, the P1020 is the preferred choice (Woodward).
Does this module support expansion chassis?A: No. Without an RTN port, it cannot connect to an expansion chassis. For expanded I/O, a CPU model supporting RTN or a revised system architecture is required.
How is the second CPU installed for redundancy?A: A second identical CPU module is required and installed according to the chassis slot rules (refer to the MicroNet chassis manual for details). Redundancy mode is then enabled in the software to support automatic failover.
What happens if the RTC battery is exhausted?A: The battery is non‑replaceable. Once depleted, the RTC stops operating and the time is lost after a power cycle. Time must be recalibrated using service tools; this does not affect control logic execution.
How to mitigate cybersecurity risks for this module?A: The module lacks security passwords and encrypted communication. Recommendations:① Deploy only on a dedicated control network, with no direct public network access;② Enable port isolation and access control lists (ACL);③ For safety‑critical applications, upgrade to a security‑enabled CPU version (e.g., 5466‑1145/1511) (Woodward).
Is the CPU module hot‑swappable?A: Hot‑swapping is possible in simplex mode (with power shutdown recommended for safety).In redundant mode, switch to the standby CPU first before servicing the faulty module, allowing bumpless transfer.
What are the required programming software and version?A: Supports Woodward GAP (graphical) and ladder logic programming, with a minimum Coder version of 4.06.When paired with an MSM module, it can achieve IEC 61508 SIL‑3 certification, subject to applicable safety programming standards.
