FOR (loop) Statements in Seeq

[Ted Williams]

Hello Seeq,

Is there a way to loop over the values of a signal in the Formula Tool editor?

 

Thanks,

Ted Williams

Hi Ted,

In the Seeq Formula editor, the transform() and filter() functions provide ways to loop over all the samples in a signal as well as all the capsules in a condition.

For example, a 2 sample running average of a signal can be calculated as shown here, by looping over each sample in the Temperature signal:

 

Giving this result:

 

As an example of looping over all the capsules in a condition, high temperature capsules lasting longer than 4 hours can be identified with this formula:

 

As shown in the trend view, only the temperature excursions longer than 4 hours are included in the “Extended High T Periods” condition:

 

I hope these examples are helpful! Please let me know if you have further questions.

John
