Sorry for the simple question here but I am still trying to learn JSON and need some help with the code for the function node.
I want to poll the MC read node every .1 second (PLC out put is set to 500ms and I don't want to miss) and if the value is true then write a T to the scanner to trigger it. In addition I want to write to a csv file the scan data and hopefully include a time stamp in the csv file. I also am trying to figure out the best way to update a variable that I can see in Node-Red for a current scan counts.
I realize this is probably very easy for some but not for me yet. Any help with the code would be appreciated. Thanks,
