Hi Amar, Thanks for the quick response. I did the following in order: 1) Downloaded your project but again no input as seen below info3.PNG 2)Stopped Codesys runtime and used PiCtory configuration & piTest and the input was read properly info4.PNG 3)Started the Codesys runtime with your project ...

Hi Amar,

Analog Input terminal 6 on RevPi Compact(0-7) corresponds to AI_Ch7 inside Codesys(1-8).
Also the variables mapped at these channels are read inside the program, as you can see below DIs are read correctly and the problem remains in AIs. Best regards

Hi dirk

This is exactly what I have done.

Hi dirk

I know, that's the way I have connected DIOs but above I was referring to Analog Inputs.
Any recommendation on these?

Best regards

Hi All, I am using a RevPi Compact with Codesys runtime. I managed to run properly RS485 comms and Digital Input/Output, but when it comes to Analog Inputs I cannot take a reading. I tried to wire Analog Output to Analog Input for a quick test but even with 2V measured with the multimeter both at th...

Hi Nicolai,

Any suggestions on why we observe this behavior and/or if there is something we can do about that.

Thanks

Hi all,

I want to connect a 3-wire PT100 on the analog inputs of a RevPi Compact, in order to use it through Codesys Runtime.
Can anyone please share a wiring diagram?

Thanks in advance

Hi Nicolai

Please have a look at this video for the behavior I mentioned.
Both DOs and Relays are triggered briefly on Power ON.
DO behavior

No, the 24V relays connected to the DO are also energized while the LEDs flicker.

Hi Nikolai, Thanks for the fast response! This seems to have fixed the digital output behavior in cases of RevPi reboot/boot but not when it is powered ON. So previously we observed two instances of DO getting all High, once when we supplied power to the RevPi and once a bit after during the booting...
