ARDI Past Point Node
This node outputs a property value from an ARDI asset in some point in the past.
This node is used in all modules and is one of the ARDI nodes.
Inputs
Default (Input #1) is the default value to output if the property is null or bad.
Delay (Input #2) is the number of samples (normally seconds) back in time that the data should be read from.
Outputs
Output #1 is the value of the point at the given time offset.
Options
This node has an option for the name of the asset and property you'd like to use. A list will appear showing likely options, but you can also simply enter the name of the point you want to use in the field provided.
Notes
When this function is used for processing events (such as in an outage analytic), all time offsets are relative to the end of the sample range.
Known Issues
Note that currently, the Past Point node is unable to retrieve information from before or after the requested data range.
In the future, we're hoping that we can support retrieving data backwards or forwards past the query edges when you've got a fixed offset (such as when you add a fixed number to the delay). However, it's doubtful this will ever function if you're using a dynamic offset.
