New user to the Historian in Ignition. Past experience with OSI PI, IP21, WW Historian.
Just wondering if there are any other functions or stored procedures that have been developed for various retrieval methods in the Historian besides the system.tag.queryTagHistory in Python. Examples might be:
1.) Discrete Tag:
a. query for returning how long a tag has been in a certain state over a time period
b. query for returning how many times a tag has transition to some value (i.e. how many times a motor has been started)
2.) Analog Tag:
a. How long was a Tag above or below a value.
b. Integration over a time period (i.e. Totalizer for taking flow rate and calculating volume or mass)
c. Counter function to determine total counts of a Tag the rolls over after a certain value.
Any help on this from the forum would be appreciated.
