Conceptual information essential to understanding how a product works.
A hierarchy is an arbitrary structure that can contain entities and calculations. These items are organised into parent-child relationships, intended to form a model of assets within an organisation. The hierarchy is the key component in the asset model, and is used to display assets in an organised manner within consuming applications such as IFS OI Explorer. This article explores how hierarchies are constructed and used.
A template in IFS OI Server is a way of defining the characteristics (attributes) of an entity, where an entity is a real world object, like a well or a pump. This article explains what templates are and how they can be used to model your assets.
Where an entity defines a real world object, it is the attributes of an entity that describe the characteristics of that object. It’s these characteristics, or attributes, that are associated with data that we generally want to model. This article explains in detail how attributes work and how they are structured within an asset model.
An Adaptor is a component of IFS OI Server that enables communication with external data systems through a configured datasource. This article describes what adaptors and datasources are and how they are used.
IFS OI Server uses data for many things. Data comes in many formats and types and IFS OI Server will treat data differently depending on this. This article explains the different types and formats of data used in IFS OI Server.
IFS OI Server is designed to provide access to data from one or more different sources. Server also has extensive data modelling capabilities, for structuring and defining this data. IFS OI Explorer represents this data on Pages, Trends, and the Tag and Hierarchy navigators.
This article gives an overview of Explorer and Server's architecture.
Dealing with time zones is critical to many operations, and becomes even more complicated when daylight savings and arithmetic operations are involved. This article describes how IFS OI Server deals with time zones.
IFS OI Server’s commenting system is a smart way of adding time stamped commentary to entities, in a common location, with extra information associated with it. This article describes how the commenting system works.
Data retrieved from external systems, such as historians, often have an associated confidence, which can be important in various calculations and applications. This article describes how IFS OI Server handles confidence.
When getting data from IFS OI Server, depending on how you set the request interval, you can get IFS OI Server to return different numbers of results. These two different methods are known as Range Fetches and Single Point (or Spot) Fetches. This article explains the differences between them.
