Re: DS18B20 Temperatur Fühler

Hi,

du brauchst einen 1Wire Buskoppler den du z.B. per USB anschließen kannst. Auf die Schnelle habe ich die Produkte von esera gefunden, die es auch für die Hutschiene gibt:

Re: MAC Address permanent change

Hi ErmannoFabbri I like to shed some light on the mac address setup of different RevPi generations: RevPi Core / Core 3(+) / Core S (until Revision 1.0) / RevPi Compact / RevPi Connect (+) / RevPi Connect S / RevPi Connect SE: The mac address is set during factory reset and can be changed afterwards...

Re: PT100 wiring on Compact

Hi

The RevPi Compact does only support 2 wire PT100 RTD, which must be connected to an input and it's 0V pendant. If the sensor is only available as 3 or 4 wire variant you could use an external temperature temperature transducer (converts the rtd to 0-10 V / 4-20mA)

Re: Node-red im Browser starten (Docker)

Hallo Andreas,

ja tut es. Der Node Red Docker versucht den selben Port zu binden. Highlander Prinzip :)

Re: Modbus Connecting Probleme

Hallo Ingo,

wir haben leider noch keinen SOS Report von dir enthalten, welcher für uns wichtige Informationen enthält.

Was für ein Core ist das eigentlich? Ein Core 3(+) oder einer der ersten Generation?

Re: Measuring Current Loop - Module is Present but not configured.

Looks like your wiring is wrong: brown should be connected with the positive voltage of the power supply white should be connected with the positive terminal of the AIO a ground wire must be connected to the negative terminal of the AIO The current you want to measure flows through the sensor Nicolai

Re: Digital Out Pins briefly switch to HI when booting

I will have another look. At the moment I'm not able to reproduce a measureable glitch on power on. Which kind of relais are you using?

Re: Digital Out Pins briefly switch to HI when booting

Do you actualy measure output voltage during power on or just observe flickering of the output LEDs?

Re: Measuring Current Loop - Module is Present but not configured.

A flashing red LED indicates Range error. A too high a voltage or too high a power supply at one or more inputs. Check the input status in the process image. https://revolutionpi.com/en/tutorials/uebersicht-aio-2/status-leds-revpi-aio-2 What is the voltage of the connected sensor? Could you please s...
