The KUNBUS products added by RS include 14 new lines including industrial computers, PLCs and data acquisition and HMI devices. KUNBUS is probably best known for its Revolution Pi series of open-source and modular industrial PCs, which are based on the Raspberry Pi platform. The modular system meets the EN61131-2 international standard for PLCs, and features a series of central processing units including the RevPi Connect, RevPi Core and RevPi Core 3. In DIN-rail housings, the products have USB, Ethernet and HDMI connections and are compatible with the Raspberry Pi model 3 or Raspberry Pi B+. The base central processing units can be expanded using digital or analogue I/O modules, as well as fieldbus gateways.
An open platform concept, the RevPi Connect gateway provides full root rights for maximum flexibility. The system uses a specially modified version of the Raspbian operating system with a real-time patch, as well as support for common IIoT protocols such as MQTT and OPC UA. Individual applications can be programmed using a range of languages including Node-RED, Python, or directly in C.
RevPi Connect can also be upgraded with PROFINET, Ethernet IP, EtherCAT, Modbus TCP and Modbus RTU functionality without the use of expansion modules.
