Memory Structure and Data Backup

Description of Regional Address Range Size

CIO area (input) CIO 0~99 100 words Built in input occupies CIO 0, automatic allocation of expansion units

CIO area (output) CIO 100~199 100 word built-in output occupies CIO 100, NA type analog output occupies CIO 190

Serial PLC link area CIO 200~289 90 words for data exchange between CPUs

Work area (W) W0~W99 100 word internal auxiliary relay

Hold zone (H) H0~H49 50 word power-off hold (battery required)

Auxiliary area (A) A0~A447 (read-only), A448~A753 (read-write) 960 word system flag and status

Timer (T) T0~T255 256 point timer

Counter (C) C0~C255 256 point counter (battery required for power-off maintenance)

Data memory (D) E-type: D0~D2047; N-type: D0~D8191 2K/8K word data storage

4.2 Memory backup mechanism

The CP1E CPU unit adopts a dual layer structure of built-in RAM (execution memory) and built-in EEPROM (backup memory):

User program: automatically saved to EEPROM during writing

Parameter area: automatically saved to EEPROM

DM area data: The specified range (E-type D0~D1499, N-type D0~D6999) can be saved to EEPROM through A751.15 (DM backup save boot bit). After setting the "Restore D0 from Backup Memory" checkbox in PLC Setup, it will automatically restore when powered on.

Battery backup (CP1W-BAT01, N/NA type only): used to maintain the hold area (H), counter (C), partial DM area, auxiliary area, and clock. Battery life: about 1.5 years at 55 ℃ and about 5 years at 25 ℃. When there is no battery, the built-in capacitor can hold for about 40 hours (N/NA type).

Engineering Tip: The DM area (D1500~D2047) of E-type without battery and EEPROM backup will become unstable after the capacitor retention time (about 50 hours) is exceeded due to power failure. The program should avoid storing critical data in this area.
