The Industrial Raspberry Pi Forum

Hello, new here so be kind! About to purchase Core and DI module for a couple of projects I have that require a rugged platform.
I see from previous posts that counting is something that is possible in th DI module. My project requires 2 Digital inputs (From switches). I intend to log every switch event with a timestamp. I would like to use Node-Red to send this data to file/database. The frequency of the switch events is around 3 per second. I am used to programming with Nodered and Python. Would what I'm intending to do be possible without a crazy amount of programming on your system? Any pointers appreciated.
I'm happy on a basic PI getting Switch events but usually these are only triggered every minute or so.

Hi, just have a look at Tutorial #14 Counter and encoder. You may get the values from Node-RED with a exec node and the command "piTest -r Counter_1". See here in the documentation how you may configure conters especially the "InputDebounce". So three counts per second will be no problem.

Thank you for your reply! Items on order will let you know how I get on.

Thank you.

Alan.
