I don't see any change in inputs value while they receive 24v on and off. Scanning all the digital inputs (with node-red) from D1 to D19 (!) and nothing is moving, while applying 24V on DI0 and DI1 having on and off 24v regularly (plugged on a production line) to be noted: no issue with USER button, and LED, only issue with the I/O on the added board root@GMSPRODASSIOT1:~# mraa-gpio list 00 IO0: GPIO UART 01 IO1: GPIO UART 02 IO2: GPIO UART 03 IO3: GPIO UART 04 IO4: GPIO PWM 05 IO5: GPIO PWM 06 IO6: GPIO PWM 07 IO7: GPIO PWM 08 IO8: GPIO PWM 09 IO9: GPIO PWM 10 IO10: GPIO SPI 11 IO11: GPIO SPI 12 IO12: GPIO SPI 13 IO13: GPIO SPI 14 A0: GPIO AIO 15 A1: GPIO AIO 16 A2: GPIO AIO 17 A3: GPIO AIO 18 A4: GPIO I2C AIO 19 A5: GPIO I2C AIO 20 USER: GPIO root@GMSPRODASSIOT1:~# mraa-gpio version Version v2.2.0 on SIMATIC IOT2050 Rgds Cyril

The jumper on the IOT2050 motherboard allows you to configure whether this power connection is made or not. This is controlled by the X82 VIN jumper, which is a small two-pin jumper on the board. In Summary: - Jumper on pins 1-2: Power is supplied from the IOT2050 to the Arduino shield (24 V DC). - Jumper on pins 2-3: IOT2050 does not supply power to the Arduino shield, and the shield must be powered separately. (SIMATIC IOT2050 Operating Instructions pag 51)
