Newbe question about RevPi Connect 4

[TheLaughingMan]

Hello everybody,

I tried to find an answer to this question in the forum, but no luck.
I mean... probably this is a very silly question: isn't in Connect 4 a digital in?

In the bottom left, pin #3, the website says it's a digital in, but I can't find it in NodeRed.

What I am missing????

Thanks in advance.

Hi Gabriele, have a look here at the documentation - it is called "RevPiStatus" at Bit 6:

Thus, you can configure this input in Node-RED as follows:

Thanks for the info!

I tried, and even applied directly 24V, but in node I can't see any change.
I also added a MIO module, using all the four digital in... nope.

Do I have to configure something in order to activate the input reading?
I tried to attach 24V directly... but nothing happens in debug.

Hi TheLaughingMan, please check if you have activated the Node-RED RevPi Nodes Server as follows:

WebStatus

Use the Shell to check the value in the process image instead Node-RED first - take a look here so maybe you have other offsets on your system:

Code: Select all

pi@revpiflashy:~ $ piTest -v RevPiStatus
variable name: RevPiStatus
       offset: 113
       length: 8
          bit: 0
pi@revpiflashy:~ $ piTest -g 113,6
Get bit 6 at offset 113. Value 0
pi@revpiflashy:~ $ piTest -q -g 113,6
0
