Technical Specifications Applicable Platform: PACSystems RX7i VME PLC system Processing Performance: High‑speed CPU core for complex user logic On‑board Memory: Expanded user program and data memory capacity Bus Interface: RX7i high‑speed VME backplane bus Built‑in Communication: Multi‑function front communication port Operating Power: Powered by RX7i rack VME backplane Operating Temperature: ‑40 ℃ to +70 ℃ Storage Temperature: ‑50 ℃ to +85 ℃ Relative Humidity: 5%‑95%, non‑condensing Mechanical Dimension: Single‑slot VME module for RX7i rack Certifications: CE, UL industrial control compliance
Functional Features High‑performance kernel executes large‑scale complex user logic control program. Expanded memory resources support massive user program and process data storage. Real‑time data interaction with all I/O and communication modules via VME backplane bus. Front‑panel LED group displays CPU run, stop mode and hardware fault alarm. Built‑in communication port supports program download, debugging and external device connection. Comprehensive hardware self‑diagnosis detects internal fault and uploads diagnostic information.
Application Scenarios Main control unit for large‑scale PACSystems RX7i automation control cabinet. Complex process‑control system for petrochemical and chemical industrial plants. High‑speed logic control for power generation and heavy‑metallurgy automation equipment.
Structural Characteristics Standard single‑slot VME plug‑in mechanical structure matching RX7i rack specification. Front‑panel LED indicator group for CPU running status and fault prompt. Front‑side multi‑purpose communication port for programming and data connection.
Working Principle After power‑on, CPU completes hardware self‑check procedure. It cyclically executes large‑volume user control logic program, reads field input data from I/O modules on VME bus, completes high‑speed arithmetic operation, and transmits output control commands to field modules.
Installation Requirements Insert CPU module into dedicated CPU VME slot of PACSystems RX7i standard rack. Rack protective grounding must strictly follow official system grounding specification. Complete hardware configuration by official PACSystems programming software before commissioning. Ambient operating environment shall keep within defined temperature and humidity range without condensed moisture.
