Circular Average

Circular Average - A function that receives a dataframe of raw tag data and computes the circular mean for samples in a range, returning the results.

Prerequisites

Ensure you have installed the RTDIP SDK as specified in the Getting Started section.

This example is using DefaultAuth() and DatabricksSQLConnection() to authenticate and connect. You can find other ways to authenticate here. The alternative built in connection methods are either by PYODBCSQLConnection(), TURBODBCSQLConnection() or SparkConnection().

Parameters

Name Type Description
business_unit str Business unit of the data
region str Region
asset str Asset
data_security_level str Level of data security
data_type str Type of the data (float, integer, double, string)
tag_names list List of tagname or tagnames ["tag_1", "tag_2"]
start_date str Start date (Either a date in the format YY-MM-DD or a datetime in the format YYY-MM-DDTHH:MM:SS or specify the timezone offset in the format YYYY-MM-DDTHH:MM:SS+zz:zz)
end_date str End date (Either a date in the format YY-MM-DD or a datetime in the format YYY-MM-DDTHH:MM:SS or specify the timezone offset in the format YYYY-MM-DDTHH:MM:SS+zz:zz)
time_interval_rate str The time interval rate (numeric input)
time_interval_unit str The time interval unit (second, minute, day, hour)
lower_bound int Lower boundary for the sample range
upper_bound int Upper boundary for the sample range
include_bad_data bool Include "Bad" data points with True or remove "Bad" data points with False
