Hi @jjansen,

I would recommend that you use a macro to calculate this average, here is an example that may be suitable for this application:

  1. Within the “Project” tab click “Macro”:

  3. Follow the instructions within this post to implement a GetData() command and pull the sampled data into the macro:
    Note: In this example I’m retrieving data from LW-59. You may need a variable to hold the total sum and average and a variable to count the number of samples. The data type I am reading this example is a short, but please configure the data type of the variable used within GetData() such that it matches the type sampled.

  4. Store the total count within HMI memory, in this example I am storing the count within LW-1000:
    Note: Information related to the SetData() command can be found within the post mentioned above as well.

  5. Add the current data to a running total and save this data within HMI memory as well:

  6. Calculate the average and set this within HMI memory:

  7. Enable periodical execution and run this macro every one minute:

  8. Click “Save & Compile” when finished:
