Dear Sir;
I am reading values from modbus devices, kwh.I want to calculate the difference on channel 65 every 8 hours.How can i do this.Could you show me a simple calculation example.

Channel 65 adjusted for the kwh.I am able to read values.But i need some calculations on it.

Let’s say;
14.08.2018 at 08:00 Chnanell 65 is 1000 kwh
14.08.2018 at 16:00 Channel 65 is 2000 kwh

i want to calculate this difference.

Thank you very much

Hello,
This calculation is difficult to implement using built in formulas because they work with current values. I suggest Elastic Report plugin, please check the demo which performs what you need.

The example shows daily difference. Elastic Report also supports hourly difference. In case of 8 hours difference, we can discuss implementing this feature.

Hi there,

I’m new to using this software.
I need to collect a live analogue value and multiply or divide it by a constant value. How can I do this?
Also, is it possible to implement a digital momentary start/stop?
Thanks

How can I do this?

For example, Cnl * 10

is it possible to implement a digital momentary start/stop?

Please clarify the question.
