Interpreting the Validation and Test Results
This topic highlights some of the visual cues used during validation and testing of a user process in Sentinel Studio.

Supplying Test Data
There are two ways to supply test data in Sentinel Studio: Manually specify single data points or Import data from a .csv file.
Validating the Logic of a Process
Before you use a user process in Sentinel, you must validate the logic of the process in Sentinel Studio to make sure it works.
Configuring a Component
Sentinel Process Components are configured in the Module tab of the properties panel in Sentinel Studio. The Module tab is automatically activated when you click on a process component. It describes the type of component and allows you to specify properties that are specific to the component.
Creating a New User Process
Before you create a user process in Sentinel Studio, you should have some idea of the mathematical logic behind your process. We recommend that you initially map this out using a flowchart or similar tool so that you have a guide to follow when using Sentinel Studio.
Building Logical Processes
Sentinel Studio is essentially a programming language that provides a visual editing tool for developing logical constructs to create a process for use in Sentinel. Before you start creating your process in Sentinel Studio, you should have a clear understanding of what your goals are and what you want to achieve.
Where to Start a Process
This article describes where to start a user process. A Sentinel process flows in a forward manner from left to right, following the path of the connected flow pins. When the process encounters a component that does not have the data it requires, the process may temporarily flow backwards in order to obtain that data, and then will resume the forward flow.
Performance Considerations in Data Windowing
There may sometimes be several ways of achieving the same result when obtaining a data point; however, whenever you retrieve a window of data using Sentinel Studio, you should be aware of potential performance issues. The more data points that you retrieve, the slower your process will run.
Process Parameters
A Process Parameter provides data to a Sentinel Studio process component. It is similar to a constant, except that it is defined by the user in Sentinel as part of the monitor configuration.
System Variables
A System Variable provides data to a Sentinel Studio process component. System variables allow access to the system states and other information that is captured during processing.
You can then use these variables as inputs to other components that have a matching data type.
