The open source IIoT gateway RevPi Connect gives users maximum freedom when implementing IIoT projects due to its open platform concept (including full root rights). RevPi Connect is based on the Raspberry Pi Compute Module 3 and features a 1.2 GHz quad-core processor, 1 GB RAM and up to 32 GB eMMC flash memory. A Real Time Clock (RTC) with 24 h buffering ensures that the device always knows what time it is, even in the event of a power failure. A specially modified Raspbian version with a real time patch is available as an operating system. Common IIoT protocols like MQTT and OPC UA are supported to transfer machine data directly to the Cloud.
Individual applications can be programmed via, amongst other things, Node-RED, Python or directly in C. The modular design of the RevPi Connect enables the 45 mm wide base device to be fitted with suitable expansion modules such as digital and analog IOs, fieldbus gateways and radio modules like for example ones for Bluetooth. The expansion modules can be joined up – plug and play – with the base device via a socket positioned at the top and can be easily configured using a graphical user interface.
2 networks – 1 device
Two Ethernet ports enable the device to be simultaneously integrated within the automation network and the IT network to transmit machinery data from, for example, the shop floor to the Cloud or a superordinate IT system.
