Functional Features HN‑revision hardware optimized for redundant operation. High‑speed logic execution and large‑capacity memory storage. Dual Ethernet communication channels. Built‑in dedicated redundancy logic processing. Works cooperatively with CMX memory synchronization module. Supports bumpless redundant switch‑over and persistent system fault logging.
Application Scenarios RX7i hot‑standby redundant control system High‑availability process‑industry control cabinet Power plant automatic control equipment Spare replacement for HN‑revision redundant CPU hardware
Performance Parameters Stable deterministic scan‑cycle performance under redundant running mode. Rapid response for redundant switch‑over action. Shock and Vibration: Complies with IEC 60068 industrial environmental standard
Material Composition Module housing: Flame‑retardant industrial plastic PCB substrate: FR‑4 high‑temperature printed‑circuit material Bus contact fingers: Gold‑plated copper alloy Internal components: HN‑revision processor, memory and redundancy processing circuit assembly
Structural Characteristics Standard RX7i plug‑in rack module form‑factor. Front‑panel LED indicators for RUN, STOP, FAULT, redundancy status and network activity. Dual RJ45 Ethernet ports and RS485 screw‑type serial terminal. Gold‑plated backplane bus contact fingers.
Working Principle CRE040‑HN CPU runs as primary controller or standby controller inside redundant RX7i rack. It exchanges real‑time runtime data with paired CMX memory‑exchange module.
Installation Requirements Insert module into dedicated CPU slot of RX7i redundant chassis. Complete cabinet protective earthing connection. Match this CPU with corresponding CMX redundancy memory module.
Usage Notes You must configure matched redundancy memory module for full redundant architecture. Respect maximum 32768 I/O point limitation strictly. Back‑up project program and configuration files on regular cycles.
