4. Product Introduction
The Beckhoff CX1100-0002 is a power supply and system interface module designed for the CX1010 and CX1020 Embedded PC series. In addition to providing 24 V DC power to the system via the internal PC/104 bus, it includes a K-Bus interface for connecting Beckhoff Bus Terminals (KLxxxx), 8 kB of NOVRAM for fail-safe data storage, and a two-line LCD for system and user messages.
Controls engineers use this module when building or repairing CX-series Embedded PC systems that require local Bus Terminal I/O. It can be replaced in the field and is one of several CX1100 power supply variants offering different I/O connectivity options. Available units are typically New Surplus or residual stock from the service phase of the product.

5. Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No power / PWR LED off | 24 V DC supply missing or incorrect | ✅ High | Measure voltage at power terminals | Verify 24 V DC supply within tolerance |
| I/O Err LED blinking | K-Bus configuration or terminal fault | ✅ High | Observe blink code pattern | Use blink code table to identify error |
| No communication with Bus Terminals | K-Bus wiring or terminal fault | ✅ High | Check terminal order and connections | Reseat terminals and verify configuration |
| Display blank or incorrect | Module fault or power issue | ✅ Medium | Check PWR LED and supply voltage | Confirm power and try power cycle |
| Process data lost on power cycle | NOVRAM issue | ✅ Medium | Test data retention after power cycle | Replace module if NOVRAM fails |
If the issue persists, record the exact LED blink pattern and system configuration before contacting support.
6. Frequently Asked Questions (FAQ)
Q: What is the main difference between CX1100-0002 and other CX1100 variants?
A: The CX1100-0002 provides a K-Bus interface for standard Beckhoff Bus Terminals. Other variants offer E-Bus, IP-Link, or EtherCAT Terminal connections instead.
Q: Can I use the -0002 with newer CX Embedded PCs?
A: It is specifically designed for the CX1010 and CX1020 series. Compatibility with later CX models should be verified in Beckhoff documentation.
Q: Does the module require a separate power supply for the K-Bus?
A: No. It supplies up to 1.75 A to the K-Bus from the 24 V DC system power.
Q: Is the -0002 still in active production?
A: It is in the service phase. New production is limited or ended; available units are primarily New Surplus or residual stock.
Q: What does the NOVRAM do?
A: The 8 kB NOVRAM provides non-volatile storage for critical process data so that values are retained during power loss.
Q: Why is pricing lower than a current Beckhoff power module?
A: This is a legacy/service-phase product sold as New Surplus or residual stock. Pricing reflects remaining inventory rather than current production cost. All units are functionally verified before shipment. Standard warranty is typically 12 months.
Q: Can the power supply module be changed in the field?
A: Yes. Beckhoff designed the series so that the power supply/interface module can be replaced without replacing the entire Embedded PC.
