In this lesson, the focus is on creating asset data and understanding what is expected to be included inside a user defined type.

Before working directly in TIA Portal, the video provides an overview using a quarter turn valve as an example. The valve is shown in different states, along with a corresponding UDT that represents its data structure. The key concept introduced is that every asset in an asset oriented programming design should have a matching UDT.

The lesson explains that UDTs can contain other UDTs. Examples include valve alarm data and asset operation mode data being nested inside the quarter turn valve UDT. These supporting structures help manage alarms, operating modes, and shared functionality across assets.

The video also discusses the types of states and data an asset must handle. This includes open and closed states, healthy and failed conditions, alarm handling, status reporting to HMIs, and both automatic and manual control requests.

A major takeaway is the importance of identifying common behavior between assets. By finding this commonality, shared UDTs such as an asset operation mode can be reused across different asset types. This approach helps standardize how assets behave and interact within the control system.

Overall, the lesson sets the foundation for turning what an asset can do and report into a structured UDT that clearly defines the data required for its operation and integration.

Latest Tip

Asset Oriented Programming starts with data, not c Asset Oriented Programming starts with data, not code. Each asset in the system is represented by a UDT that captures all required information for control, status, alarms, and interaction with higher level systems.

In this lesson, a quarter turn valve is used to illustrate how an asset exists in multiple states such as open, closed, healthy, and failed, and how those states must be represented explicitly in data. The UDT becomes the single source of truth for the asset's behavior.

This approach allows logic, HMI, and diagnostics to rely on a consistent structure. When data is clearly defined up front, function blocks become simpler and more reusable.
