Hi Dojo,
How can I add parameters from two different connectors?
For example, I want to retrieve param_A from Connector A and param_B from Connector B.
Using a Virtual Connector, I can perform "Replication" and place both parameters on the same page.
Next, I want to calculate param_A + param_B = param_C.
I tried using "Sequence noset," but it doesn't work. I also tried using QAction, but it doesn't work either.
Please advise.

Hi Miguel,
My goal is for the sum of paramA and paramB to reach a certain value, which will then set another parameter to On or Off.
Can aggregation and correlation accomplish this?
Hi Greisen,
For this use case, you could use aggregation rules. Below an extra of an aggregation rule that sum rows from a column parameter (you can also aggregate single parameters):
As you can see, you can assign thresholds to the aggregated value. You can use this alarm to trigger a correlation rule:
Below a correlated alarm:
Hope it helps.
Hi Miguel,
Thank you for your detailed explanation; it enhances my understanding of correlation.
Unfortunately, the aggregator only functions if the element has the same connector.
Hi Greisen,
Indeed, this option only works if the connector is the same.
Another option is to use GQI queries (in a dashboard) to extract information from elements, so you can perform operations.

Another option, this time connector related, is to use data distribution. This feature allows you get a parameter value from another element. In that way you can perform the aggregation in the connector:

Hope it helps.
Hi Greisen,
Small question, is it required to perform the aggregation in one of the connectors? Is it an option to use aggregation rules:
