Working Principle:
The CP048 runs a real-time operating system (B&R Real-Time OS) on the ARM Cortex A8 processor. The controller executes the user program (IEC 61131-3 or C) in a deterministic scan cycle. I/O data is exchanged with X20 modules via the X20 backplane bus at high speed. Motion control tasks are executed by a dedicated motion control core within the processor. Communication with HMI panels, SCADA systems, and other controllers occurs via the dual Ethernet ports using standard industrial protocols.
Advantages & Highlights:
- High processing power (800 MHz ARM Cortex A8) enables complex control and motion tasks
- Integrated PLC + Motion + HMI in a single compact controller
- Dual Ethernet ports allow network separation (control network + diagnostic network)
- SD card enables standalone data logging and easy firmware management
- Full IEC 61131-3 compliance with all five programming languages
- Cost-effective alternative to separate PLC + motion controller + HMI
Applicable Industries:
- Packaging machinery
- Printing and converting
- Material handling and conveyor systems
- Small to medium machine builders
- Robotics (pick-and-place, SCARA)
- Textile machinery
Installation Requirements:
- Mount on DIN rail (TS 35 x 7.5 or TS 35 x 15)
- Connect to X20 base module (X20BC0083 or X20BC0093) for I/O expansion
- Connect Ethernet cables to controller network and optional HMI/SCADA network
- Insert Micro SD card for data logging (formatted as FAT32)
- Ensure 24 V DC power supply with adequate current capacity (minimum 1 A recommended)
Usage Precautions:
- Do not disconnect X20 modules during active operation (unless hot-swap is configured)
- Use industrial-grade Ethernet cables (shielded) for reliable communication
- Do not exceed ambient temperature of +55 °C
- Perform firmware updates only through official B&R Automation Studio
- Back up the program to SD card before any configuration changes
