I have a task that I am performing however I have some questions, hopefully you can guide me and answer a few of my questions.
First, I am using the control tool to add a Microsoft List Box to display the timestamp and value every time the PI Point updates. However, I noticed that every time I close Pi Processbook, and re open it OR sporadically it will delete the previous recorded values. My goal is to have this list as a running historian, without having values deleted. How can I do this?
Next question is I would like to write some code, that when a number turns from 1 to 0 (here let’s say inverter status with 1 being ON), it will bring up the inverter name and timestamp of when the inverter went off.
