Powered by Raspberry Pi Compute Module 4
The Raspberry Pi Compute Modules are so-called System on Modules (SoM) and have been developed since 2015 especially for use in industrial environments. The Raspberry Pi Compute Module 4 used in the RevPi Connect 4 is the latest version of the Compute Module and has a PCIe interface and optional WLAN/Bluetooth for the first time.
Software
A 64-bit Raspberry Pi OS customized by us is once again pre-installed as the operating system, which includes a real-time patch and a process image, among other things. The RevPi Connect 4 has master and slave capabilities for the common Modbus RTU and Modbus TCP protocols as standard. With optionally available control and HMI software such as CODESYS, for which there are suitable drivers for seamless integration of the RevPi Connect 4 and its expansion modules, the device can be expanded into a small industrial controller.
Key features
- Customized 64-Bit Raspberry Pi OS
- Full root rights
- Trusted Platform Module (TPM)
- 4 KB process image
- Graphical configuration tool
- Driver for seamless integration into Node-RED & CODESYS
- Modbus TCP & RTU Master/Slave functionality
