Technical Specifications Storage Medium: Non‑volatile flash memory Main Function: User program, configuration, firmware file storage and backup Interface: RX3i backplane bus and auxiliary serial port Operating Power: Supplied via RX3i rack backplane Operating Temperature: ‑40 ℃ to +70 ℃ Storage Temperature: ‑50 ℃ to +85 ℃ Relative Humidity: 5%‑95%, non‑condensing Mechanical Dimension: Single‑slot accessory module for RX3i rack Certifications: CE, UL industrial component compliance
Functional Features Non‑volatile flash storage keeps program and configuration data without battery power supply. Supports firmware upgrade and user program backup via serial port. Realizes data interaction with RX3i CPU through high‑speed backplane bus. Front‑panel LED indicates module running and access status. Supports hot‑swap replacement under system running state. Facilitates on‑site program duplication and equipment commissioning work.
Application Scenarios Program backup and firmware update for RX3i PLC controllers. On‑site equipment commissioning for chemical, manufacturing and process automation projects. Data storage for production‑site PLC control logic and configuration parameters. Hardware spare‑part replacement scenario for rapid program restoration.
Structural Characteristics Standard single‑slot plug‑in structure matching RX3i rack specification. Front‑panel LED status indicator for module access condition. Auxiliary serial port on front face for local file operation. Backplane golden‑finger interface for data exchange and power acquisition. Locking mechanism for firm installation inside rack against vibration displacement.
Working Principle The module obtains operating power from rack backplane bus. It exchanges program, configuration and firmware data with RX3i CPU via internal bus. User can read‑write flash storage content either through backplane by CPU or through front‑side serial port.
Installation Requirements Insert module into designated slot of RX3i standard rack. Complete rack protective grounding complying with official system grounding specification. Hot‑swap replacement shall strictly follow on‑site industrial safety operation procedure. Ambient installation environment shall stay within defined temperature and humidity range without condensed moisture.
