Description
1. Product Overview
The Beckhoff CX1100-0001 is a specialized Power Supply and I/O Interface module designed to serve as the foundation for CX-series Embedded PCs (specifically CX1010, CX1020, and CX1030). More than just a power source, this module acts as the vital link between the high-performance CPU and the standard Beckhoff Bus Terminals (K-Bus).
Equipped with a built-in 2×16 character display and four navigation keys, the CX1100-0001 allows for localized status monitoring and basic system diagnostics without the need for an external monitor. It ensures stable 24V DC power distribution to both the internal CPU electronics and the connected I/O slice modules, making it an indispensable component for DIN-rail mounted control systems.
Key Applications:
- Compact Control Systems: Powering CX-series PCs in space-constrained electrical cabinets.
- I/O Signal Management: Interfacing standard K-Bus terminals with the TwinCAT control logic.
- On-site Diagnostics: Using the integrated LCD to check IP addresses, system status, or error codes.
- Industrial Automation: Widely used in machine building, building automation, and assembly lines.

7. FAQ
Q: What is the difference between CX1100-0001 and CX1100-0002?
The CX1100-0001 is designed for the standard K-Bus (Bus Terminals), whereas the CX1100-0002 is designed for the high-speed E-Bus (EtherCAT Terminals). Make sure you check your I/O slice type before ordering!
Q: Can I use the display to set the IP address?
Yes, if your TwinCAT project is configured correctly, the display and keys on the CX1100-0001 can be used to navigate system menus and view/edit basic network settings like the IP address.
Q: Is the 24V power supply for the field devices included?
The module provides power to the internal electronics and the bus. Power for the field devices (contacts, sensors, etc.) must be fed separately into the power contacts of the Bus Terminals.
