Hello everyone,

I have a question regarding the implementation in Ignition using the Power Chart. I have two historical curves: one for speed and one for production status, representing both Product 1 and Product 2.

My goal is to display the speed trend for all products in the Power Chart. Additionally, I would like to have the option to filter the display so that only the speed for Product 1 or only for Product 2 is shown.

Can anyone provide some guidance on the best way to implement this? Should I create additional data sources for the filtered speed curves, or is there a more elegant solution within the Power Char

t?

Thank you in advance for your help!

The tag historian doesn't have any native tools/methods that segregate or correlate signals by the status of other historized signals.

You should record the speed and the product ID in the same row of a table, with timestamps. The supported way to do that in Ignition is to record with a transaction group. Then make manual pens with the Wide Table DB Historian tool, keying on the product ID.

(You can also script inserts to a table from gateway events, if you do not want to purchase the SQL Bridge module.)
