All-in-one PLC for embedded systems based on Raspberry Pi
A compact embedded PLC implementing CODESYS based on the Raspberry Pi module CM4 board computer.
Contec has been contributing to the development of industrial use of PCs since 1982, when it launched its interface boards necessary for building PC-based measurement and control systems, with the catchphrase "Bringing the Ease of PCs to FA." The company has continued to innovate and adapt to expanding buses and operating systems. In April 2021, it developed the "CPI Series," a HAT-sized board for signal input and output compatible with the Raspberry Pi, which is the global standard for board computers. This series leverages the high cost performance and customization capabilities of the Raspberry Pi for applications in the measurement and control field. The product is a compact embedded PLC based on our original board computer using the latest embedded module CM4 from Raspberry Pi, and it implements the world's most widely used software PLC, "CODESYS." Utilizing our extensive asset of peripherals for Raspberry Pi, including the "CPI Series," users can build various control applications using the IEC 61131-3 compliant world standard PLC language.

Detailed information
-
■High compatibility with Raspberry Pi 4 The Raspberry Pi, boasting cumulative shipments of over 60 million units, has its core components modularized for industrial use in the Compute Module 4 (CM4). This ensures high compatibility with Raspberry Pi. It guarantees the reliability and environmental resistance essential for industrial controllers. Designed for a wide temperature range of -20 to 60°C (airflow 0.7ms). It incorporates our well-established RTC/RAS board for Raspberry Pi (CPI-RAS), providing watchdog timer (WDT) and real-time clock (RTC) functions. Equipped with a high-output, high-efficiency power circuit and a noise filter to eliminate external noise, it generates clean 5VDC to supply the internal circuits.
-
■CODESYS(R) Pre-installed Pre-installed software PLC "CODESYS," adopted by over 400 OEM manufacturers worldwide and shipped over 1 million units annually. It allows programming in PLC languages compliant with the international standard IEC 61131-3. (Only for CPI-PS10CM4) This enables the accumulation of software assets using a common language independent of vendors, enhancing the reusability of programs. It also supports the third edition of IEC 61131-3 and allows for object-oriented programming. Equipped with a quad-core Cortex-A72 (ARMv8) 64-bit SoC @ 1.6GHz, 2GB DDR4 high-speed memory, and 16GB eMMC. - Basic arithmetic processing speed (LD instruction): 1.86ns (Measured value by our company) - Application arithmetic processing speed (ST instruction): 2.06ns (Measured value by our company) - Program capacity: 3MB - Number of input/output tags: 512 (16-bit data also counts as 1 tag) Equipped with an M.2 M Key NVMe socket. It can support applications requiring high-capacity storage for high-speed long-term data collection and rich HMI.

■HAT size board for I/O expansion Equipped with the same HAT (Hardware Attached on Top) 40-pin header GPIO as Raspberry Pi. This allows for the utilization of Raspberry Pi peripheral assets. Our CPI series measurement and control interface boards for Raspberry Pi, from a manufacturer of PC-based measurement and control systems, can be used in up to 8 units. I/O necessary for FA control systems, such as digital input/output, analog input/output, and counters, can be expanded via a local bus (I2C).
-
■IoT and Industrial Open Network Support Enhanced industrial network communication capabilities. Supports EtherCAT, PROFINET, EtherNet/IP, and Modbus. Equipped with OPC UA server and Web HMI functionality. (SoftMotion is optional)
