A report to be generated for few tags of 20 based on a click from HMI.
This report file should have continuous rows of data based on clicks from HMI ( during some operation, operator would prefer to log the data to the report file).This means that with every new click a new row will be added with current time and data logged during the time.
There should be another click from HMI which means now they can create a new file and start to log the data in the new file.
Two Clicks - First click for start data log & Second click for creating a different file.
With the Calculation Aspect (You need the calculation engine, inkl. Licence!!), you are able to create log on an event. You need an LogTemplate for "Lab Data" and not "Direct". So you can store the values on events (HMI Button). So you store all the values for each row in a the log. Then you need to create the Report template with the Lab-Data-Logging, with all the values you have stored in the log.
