Detect Addon module Connection Status - NodeRed

[mitchellday06]

Hi,
I was wondering if there is any type of module state detection for addon modules in NodeRed.

I have 2 x MIO an AIO and a DIO. I wanted to have checks to see if the state disconnects or errors, then to perform some logic.

Hi ,

you can monitor the modules, but this is different depending on the modules.

Make sure that you have set up your hardware correctly in PiCtory as Start-Config. and that Node-RED & the Node-RED RevPi Nodes Server is activated in Webstatus.

For the DIO module you can evaluate the variable "PIN: Status", if the module is OK it will give you a 0, if it fails an 841. For the AIO, you can analyze a status for each individual input and output. The variables are called OutputStatus_1 & InputValue_1 and so on. Unfortunately, the MIO itself does not provide a status.

Thank you for your contribution here in the forum, we have some homework to do so that all modules provide uniform statuses with documented error codes in future.

So if I analyzed an analogue input on the AIO, it could return a fail purely because of that one input? So to know if it is the module, would have to return failed for all?
