Product Short Description
Product Name: BERGHOF CE3CPU-1131 Programmable Logic Controller (PLC) CPU Module.
Product Overview: A compact, high-performance CPU module from BERGHOF’s CE3 series, serving as the central control unit for small to mid-sized industrial automation systems. It is programmed using CODESYS according to IEC 61131-3 standard.
Description
Technical Specifications:
- Processor: 32-bit ARM Cortex-A8, 1 GHz clock speed
- Memory: 512 MB RAM, 1 GB Flash
- Power Supply: 24 VDC
- Communication Interfaces: 1 × Ethernet (10/100 Mbit/s), 2 × RS-232, 1 × RS-485
- Supported Protocols: Modbus TCP, Modbus RTU, CANopen
- I/O Capacity: Expandable via additional I/O modules; supports up to 256 I/O points
- Video: Supports CRT and 18-bit TFT LCD displays (640×480 to 1280×1024 resolution)
- Additional Interfaces: USB, parallel port, IrDA, PS/2 keyboard/mouse, digital I/O
- Operating Temperature: 0°C to +60°C
- Dimensions: Approx. 200 × 40 × 50 mm
- Mounting: DIN rail
Functional Features:
- High-speed processing for complex control logic and data handling
- IEC 61131-3 programming (ladder, structured text, function block, etc.) via CODESYS
- Modular expandability to tailor I/O count to application needs
- Rugged industrial design resistant to shock, vibration, and electromagnetic interference
- Built-in real-time clock and watchdog timer
- Hot-swappable I/O module replacement for reduced downtime
Working Principle: The CPU module executes the user-written control program stored in Flash memory. It scans inputs from connected I/O
modules, processes logic according to the IEC 61131-3 program, and updates outputs. Communication with HMI, SCADA, or peer controllers is
handled over Ethernet or serial interfaces using Modbus or CANopen protocols.
Application Scenarios: Machine control (packaging machines, injection molding machines), process control (temperature, level), automated
test systems, building automation, and material handling systems.
Installation & Usage Notes:
- Mount on standard DIN rail inside a control cabinet; ensure ventilation for heat dissipation
- Supply clean 24 VDC power with proper fusing and grounding
- Separate high-voltage and communication cables to prevent EMI-induced errors
- Program and configure exclusively through CODESYS software
- Observe the 0°C to +60°C operating temperature range; derate for higher ambient temperatures
- Back up the application program and configuration before module replacement
