Selection Guide
Use the table below to select the right CX-series CPU for your application:
- Legacy TwinCAT 2 system, no change needed: → CX1020-0000 (this model) or CX1030-0000
- New design, TwinCAT 3, moderate I/O: → CX5010-0110 or CX5020-0110
- Cost-sensitive, small I/O count (<128 points): → CX9020-0100 or CX8090
- High-performance motion (4+ axes): → CX5130-0120 or CX5140-0120 (Intel Core i7)
- Hazardous area (ATEX Zone 2): → CX1020-0000 (certified) — verify with Beckhoff for CX5xxx ATEX variants

Replacement & Compatibility FAQ
Q: Can the CX1030-0000 directly replace the CX1020-0000?
A: Yes. The CX1030-0000 uses the same housing and connector layout. It offers a faster CPU (1 GHz vs 600 MHz) and is a drop-in hardware replacement. TwinCAT projects may require recompilation.
Q: Is the CX1020-0000 compatible with TwinCAT 3?
A: Limited support only. TwinCAT 3 requires a minimum of 1 GHz CPU. For full TwinCAT 3 functionality, upgrade to CX5010 or higher.
Q: What CF card is recommended for the CX1020-0000?
A: Beckhoff recommends industrial-grade CF cards (SLC NAND). Minimum 512 MB for Windows CE; 2 GB+ for Windows XP Embedded.
Q: Can I use third-party fieldbus modules with the CX1020-0000?
A: No. The CX1020 fieldbus slot is proprietary to Beckhoff CX1020-N0xx series modules.
Q: What is the end-of-life status of the CX1020-0000?
A: Beckhoff has announced the CX1020 series as discontinued. Spare parts and replacements remain available through authorized distributors and surplus suppliers like Konmask.com.
