True or False: The type of engineering unit identified for a tag affects how its data is stored and calculated.

The correct understanding is that the type of engineering unit identified for a tag does indeed influence how its data is handled, particularly in terms of calculations and conversions. Engineering units provide context to the data collected, indicating what type of measurement is being made (e.g., temperature in Celsius or Fahrenheit, pressure in PSI or Pascals).

When a tag is assigned a specific engineering unit, the system is able to properly interpret the data according to that unit, leading to accurate calculations and ensuring consistency across datasets. This is crucial for both data storage and visualization, as it determines how the data are presented and analyzed in reports and dashboards.

Therefore, it's important to recognize that the type of engineering unit indeed affects how data for a tag is stored and calculated, making the assertion that this is false incorrect. In conclusion, the influence of engineering units on data handling is a significant aspect of the functionality of the AVEVA Historian Server, relevant to ensuring data integrity and accuracy.
