Re: RevPi Compact & Codesys

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.

Re: RevPi Compact & Codesys

Hi dirk

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

RevPi Compact & Codesys

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...

Re: Digital Out Pins briefly switch to HI when booting

Hi Nicolai,

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

Thanks

PT100 wiring on Compact

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

Re: Digital Out Pins briefly switch to HI when booting

Hi Nicolai

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

Re: Digital Out Pins briefly switch to HI when booting

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

Re: Digital Out Pins briefly switch to HI when booting

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...
