Based on the Raspberry Pi Compute Module, KUNBUS has developed an industrial PC composed of open hardware and software meeting the EN61131-2 standard. Thanks to the modular structure, Revolution Pi can, depending on customer requirements, be supplemented by digital or analogue I/O modules respectively as well as appropriate fieldbus gateways to connect it to an industrial network. Installed in a DIN rail housing, the base module of the Revolution Pi already has USB, Ethernet and HDMI connections. The base module and expansion modules are supplied with 24 volts.
In addition to revealing the circuit diagrams, KUNBUS is rigorously pursuing the Open Source concept within the software. The established Raspbian operating system from Raspberry Pi, including the drivers for the expansion modules, are preinstalled. Using Raspbian ensures that basically any software or application running on Raspberry Pi will also run on Revolution Pi. Full root access allows obstaclefree programming and implementation of customised programs. By cooperating with various software manufacturers, KUNBUS provides inexpensive and powerful control and SCADA software for users preferring off-the-peg software solutions. As a result, Revolution Pi can be developed into an industrially viable small control system/PLC.
