Data write rate - too much!

[Craig2]

I'm using an Action module to Write data to hard drive.  The Action module is set to Input Above Threshold but the Write keeps writing irrespective of the threshold.  I only want to Write data above the thresholds and I have piles of written data below it.

Also, can I slow the Write rate down.  I only need Write data about every 250mSec.  System is going to run 24/7 and the alarm outputs are crucial, but written data is just for trending.

The Action module does not affect the data flow rate.

You must interrupt the data flow with a Relay module; you can either use a Trigger module to monitor your event, or the Action module, and use it to Open and Close the Relay.

There are a number of data reduction examples in the Help->Tutorial - it's worth the time to read through them. I generally suggest that at least the first 4 chapters / sections be read. It helps set the environment and fundamentals.
