Berghof CE3CPU-1131
Product Name
Berghof CE3CPU-1131 programmable logic controller CPU module.
Product Introduction
CE3CPU-1131 is a compact industrial CPU for Berghof CE3 automation systems. It executes IEC 61131-3 control programs, communicates with I/O modules, HMIs, and higher-level networks, and supports machine and process automation applications.
Detailed content
Technical Specifications
Processor is 32-bit ARM Cortex-A8 at 1 GHz. Memory includes 512 MB RAM and 1 GB Flash. Power supply is 24 VDC. Communication interfaces include one Ethernet 10/100 Mbit/s, two RS-232, one RS-485, and one CANopen. Supported protocols include Modbus TCP, Modbus RTU, and CANopen. Video interface supports CRT and 18-bit TFT LCD with resolutions from 640×480 to 1280×1024. Additional interfaces include USB, parallel, IrDA, PS/2 keyboard or mouse, and digital I/O. Typical operating temperature is 0 to 60°C.
Function Features
IEC 61131-3 programming through CODESYS or Berghof engineering tools, expanded I/O capacity through additional modules, high-speed logic processing, multiple serial and Ethernet networks, and local human-machine interface support.
Application Scenarios
Packaging machines, injection-molding machines, conveyor and material-handling control, temperature and level process control, automated test systems, and building or factory automation.
Performance Parameters
Program execution performance is sufficient for complex logic, PID control, and data handling under deterministic scan cycles. Ethernet throughput supports Modbus TCP HMI and SCADA communication. CANopen and RS-485 support distributed I/O and servo drives.
Material Composition
Industrial printed-circuit assembly with metal or flame-retardant enclosure components. Connectors use plated contacts suitable for control-cabinet environments.
Structure Features
DIN-rail mounting format with separate communication, video, USB, and I/O connectors. Module dimensions in common distributor documentation are approximately 200 mm x 40 mm x 50 mm, though exact mechanical drawings should be confirmed from Berghof drawings.
Working Principle
The CPU reads inputs from local and remote I/O modules, executes the IEC 61131-3 application, updates outputs, and exchanges data with HMI, SCADA, or peer controllers. Ethernet, RS-232/485, and CANopen ports handle programming, diagnostics, and field communication.
Installation Requirements
Mount on a standard 35 mm DIN rail inside a ventilated control cabinet. Supply clean 24 VDC with proper fusing and grounding. Separate high-voltage wiring from communication cables. Confirm cabinet temperature remains within the specified operating range.
Usage Notes
Program only with supported Berghof or CODESYS toolchains configured for CE3CPU-1131. Back up application and configuration before module replacement. Avoid mixing incompatible firmware versions. Maintain separation between communication and power cabling to reduce electromagnetic interference.
