Problem with trend data
#1
Good morning,

I have a Logic Machine on a plant where we monitor heat and electric meters. 
I have found a problem in the trend log data.

For a heat pump there are a heat meter and an electric meter that monitor the heat and electric power. The meters are integrated with Modbus RTU protcol.
Then we have a resident script that calculates a coefficient which is the heat power / electric power.

We have 3 trend log that have the following configuration:
 - Absolute value
 - Average
 - Every 5 minutes

The problem is that we have some data that are not right (there is an image of data in the upload).

For example, in the image, the first column is the result but at 3:15 there is a value that is completely wrong.
For the others rows the result seems to be correct.

Have you ever had some problems on the trendlog that compute the average?

Thank you in advance
