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.
