Hi Tahsin,

You have a few options. You could try changing the deadband on the floating points to a number less than one, like .01 for example. You could also log the data on any change:

Here is a post on how to log data based on an event instead of constantly:

HOW TO: Event driven historical logging

How to log data based on an event Many times we may not want historical data to run all the time. There may be times where we need to start logging when an action occurs and stop when this action has completed. Say for example we have an assembly line that begins sending items down the line when a button is pressed. Say we only want to log the data between button presses to calculate a pinpointed average for the amount of items sent down the line. We could theoretically do this with regular lo…

You can log a group of tags on an event like this:

This does not count towards the 1 million historical log data point storage maximum in the eWON’s memory. If you’d like to log a group of tags when a tag changes in value, you can do that as well but you’ll need to use scripting and be on firmware version 12.2 FW available here: https://websupport.ewon.biz/support/product/manual-firmware-update/manual-firmware-download You can use the ONCHAN…

Please let me know if you have any questions.

Can you please email the script?

Thanks,

I sent you the instructions on how to do it and the options that you have. I didn’t say I was going to write you a script. Sorry for your misunderstanding.
