Content Sections:

1. Mission-Critical Reliability
   Designed for >99.999% uptime in continuous processes. Features error-correcting code (ECC) memory and built-in watchdog timers that trigger automatic fallback during faults.

2. Cybersecurity Architecture
   Integrated TPM 2.0 chip enables secure key storage and encrypted communications. Supports role-based access control (RBAC) meeting NERC CIP requirements for power infrastructure.

3. Migration Advantage
   Backward-compatible with legacy AC 800M CPUs (PM864, PM865). Reduces retrofit costs by 40% through reusable configuration files and I/O mappings.
