🔧 3. Detailed Functional Features

Dual Microprocessor Architecture: Includes two clock-synchronized microprocessors. One processes actual data and programs, while the other processes inverted data and programs. This ensures continuous cross-checking for errors .
Hardware Comparator: A testable hardware comparator monitors all external accesses by the two microprocessors. If a discrepancy is detected, the system triggers a safe state (e.g., via a watchdog) to prevent hazardous operations .
Memory System:
- Flash-EPROM: Stores the operating system and user programs, supporting a minimum of 100,000 write cycles .
- SRAM: Used for data storage, backed by a battery to prevent data loss during power interruptions. The battery (HIMA P/N 44 0000018) typically requires replacement every 6 years or when indicated by a “BATI” warning .
Communication Capabilities: Supports various industry-safe protocols like Profibus DP-V1 and HIMA’s proprietary safety protocols. It can interface with up to five communication modules in a H51q-HS PES system, facilitating integration into broader DCS or PLC networks .
Input/Output (I/O): Functions as a safety I/O module, handling both digital and analog signals with specific safety integrity levels for critical functions .
