Kunbus RevolutionPi RevPi Core Raspberry Pi based Industrial Computer Sells with Digital I/O Modules and Fieldbus Gateways

Kunbus, a German company specialized in industrial network solution, has decided to design an industrial system based on Raspberry Pi Computer module supporting variable power supply, a wide temperature range, DIN rail mounting, etc, as well as corresponding digital I/O modules and fieldbus gateways.

industrial-raspberry-pi-revpiRevolutionPI RevPi Core specifications:

  • SoC – Broadcom BCM2835 ARM11 processor @ 700 MHz
  • System Memory – 512 MB
  • Storage – 4GB flash
  • Video Output – Micro HDMI port
  • Connectivity – 10/100M Ethernet port
  • USB – 2x USB 2.0 host ports, 1x micro USB port
  • Misc – RTC, 3x status LEDs (2 programmable)
  • Power Supply – 10.7 V to 28.8 V; polarity protection; 4 kV / 8 kV ESD protection & EMI passed (according to EN61131-2 and IEC 61000-6-2), surge and burst tests passed
  • Power Consumption – Max: 10 Watts including 2 x 450 mA USB load; typ.: 4 watts.
  • Dimensions – 96 x 22.5 x 110.5 mm (Polycarbonate case)
  • Housing type – DIN rail housing for DIN rail version EN 50022
  • Weight – 108 g
  • Protection class – IP20
  • Temperature Range – Operating: -40 °C to +55 °C (exceeds EN61131-2 requirements); storage: -40 °C to +85 °C (exceeds EN61131-2 requirements); N/B.: No guarantee that the system can start at less than 30 °C with a 24V power supply.
  • Humidity – up to 93% (non-condensing) @ 40°C

The system runs Raspian Wheezy with RT-patch for Linux kernel 4.1.13.

Beside RevPi Core described above, the company also offers three different galvanically isolated “RevPi DIO” digital IO modules with a 28-pin I/O connector as shown in the first picture, as well as RevPi Gates gateways supporting industrial communication standards including Profinet, Profibus, EtherCat, Modbus, Sercos, CANopen, and more. RevPi DIO and Gates are connected to RevPi core through a overhead Pi Bridge connector allowing two expansions per RevPi Core.

Raspberry BCM2835 chip is available to all , thought they exclusively make only for the raspberry foundation

Hmmm…all the fieldbus modules are slaves, not masters, but they do have a good selection, including Profibus IRT and Ethernet Powerlink. Pricing is reasonable for industrial, but only allowing 2 expansions is very limiting.

Other than using a RPI, what benefit is there over prevous means?

Depending on the Ethernet chip on the main board they could run “software” fieldbus masters on the “core” module. All they need is RT kernel and efficient ethernet driver.
LOGI.CAD3 (the PLC solution that they use) have some references to acontis EtherCAT master so is seems probable.
In fact they only need one fieldbus slave in given machine and one or more IO modules. They have RS485 on the interconnection bus so it could accept multiple “slower” modules.
I am quite interested which company provides the fieldbus slave solutions – I suspect they rely on some proven name in this area – anybus, hilscher?

A BeagleBone version would be far more useful

Yes indeed. Ethercat slave could be implemented using the PRUs of the Sitarta.
