Functional Features: Powerful program storage and data memory capacity for complex automation control logic; built‑in multi‑mode serial communication port supports program debugging, host‑computer data exchange and HMI connection; hardware self‑diagnosis function detects program error, backplane bus fault and internal hardware damage; fault‑code storage mechanism facilitates on‑site troubleshooting; backup lithium battery maintains retentive DM memory data during main power failure; full compatibility with complete CV‑series I/O units and special‑function expansion modules.
Application Scenarios: Legacy medium‑and‑large‑scale factory automation control systems; automobile manufacturing production‑line control; large packaging machinery control; material conveying system automation; old CV‑series PLC system maintenance and spare‑part replacement; process industry auxiliary equipment control.
Performance Parameters: Electromagnetic compatibility performance complies with industrial control component standards; vibration and shock resistance meet cabinet‑mount equipment test criteria; supports continuous 24‑hour long‑term operation inside industrial control cabinets under non‑condensing environment.
Material Composition: Black V0 flame‑retardant engineering‑plastic housing; internal FR‑4 multilayer glass‑fiber printed‑circuit board; industrial‑grade main‑control processing chip; gold‑plated backplane edge‑connector contacts; lithium backup‑battery assembly; high‑brightness multi‑color LED status indicators; metal mechanical locking clips.
Structural Features: Standard CV‑series rack‑slot physical profile; gold‑plated edge‑connector on rear housing surface interfaces with CV‑series main rack backplane bus; front‑panel equipped with 9‑pin D‑SUB peripheral communication port; multiple groups of RUN‑ERROR status LED indicators arranged on front‑panel surface; side metal locking latches fasten CPU unit into designated CPU slot of CV‑series main rack.
Working Principle: CV2000‑CPU01‑EV1 runs cyclic scan cycles: reads all input‑module signal states from main‑rack and expansion‑rack backplane bus; sequentially executes user‑written control program; refreshes output‑module state data onto backplane bus. Built‑in peripheral serial port handles program upload‑download and external‑device data‑exchange tasks. Internal self‑diagnosis circuit continuously monitors hardware operating state, illuminates alarm‑indicator and stores fault‑code information when abnormal events occur. Backup lithium battery maintains retentive‑memory content upon main‑supply power failure.
Installation Requirements: Install CV2000‑CPU01‑EV1 into dedicated CPU slot of CV‑series main rack; fasten CV‑series main rack onto cabinet DIN rail; reserve adequate heat‑dissipation clearance surrounding CPU‑module housing; deploy shielded cable for peripheral‑port serial communication wiring; separate communication‑signal cables from high‑power dynamic cables; implement reliable protective grounding for control cabinet.
Usage Notes: Hot‑swap operation for this CPU unit is strictly prohibited; replace backup lithium battery according to specified service cycle to avoid loss of retentive memory data; complete full user‑program backup after programming work; read stored fault‑codes for equipment‑failure‑analysis work; do not deploy in environments with corrosive gas or condensation.
