从TIA 博途 V11 开始，S7-1200 支持PLC数据类型（UDT）。 UDT类型是一种由多个不同数据类型元素组成的数据结构，元素可以是基本数据类型，也可以是STRUCT、数组等复杂数据类型以及其它UDT等。 UDT类型嵌套UDT类型的深度限制为 8 级。 UDT类型可以在DB、OB/FC/FB接口区处使用。 从TIA 博途 V13SP1 开始，S7-1200 V4.0开始，PLC变量表中的I和Q也可以使用UDT类型。 UDT类型可在程序中统一更改和重复使用，一旦某UDT类型发生修改，执行软件全部编 …

In this article, we will talk about the UDT or user-defined data types and how to use them for better and faster PLC project structure. Contents: What is a user-defined data type -UDT-? Why would I need UDT? How to create a UDT? Applying the concept to previous tank simulation examples. Conclusions. What is a User-defined Data Type?

User Defined Data Types or UDTs are commonly used in Programmable Logic Controller Programming in order to group data and maximize code reusability. This structure allows the user to combine any of the existing data types into a package which can be reapplied multiple types across the program, be exported and imported into other structures.

Oracle Data Provider for .NET supports Oracle object types or user-defined types (UDTs), which are defined in the Oracle database. There are two kinds of UDTs: Additionally, ODP.NET supports references (REF) to object types. The term UDT is used interchangeably with Oracle object types and abstract data types (ADTs).

2023年8月8日 · User-defined data types (UDTs) are a powerful and useful tool when applied to their full advantage. However, misused, they can become problematic and introduce roadblocks to troubleshooting and upgrading PLC programs.

A user-defined data type (UDT) is a data type that derived from an existing data type. You can use UDTs to extend the built-in types already available and create your own customized data types.

In this tutorial will look at some advanced data types used in Siemens PLC programming. We will learn how to use them, how to apply them to real world projects, and how to customize them in Siemens TIA Portal.

2023年7月24日 · How do you program user-defined data types (UDTs) in STEP 7 (TIA Portal)? In this Video we will see how do we program user-defined data types (UDTs) in STEP 7 (TIA Portal) to create a PLC data type, in the project navigation you open the "PLC data type" folder and double-click "Add new data type". Beginning of dialog window.

UDT stands for "User-Defined Data Type." It is a feature in database management systems that allows users to create custom data types to suit their specific needs. While most database systems come with predefined data types like integers, strings, dates, etc., UDTs offer the flexibility to define new data types that can represent more complex ...

If you don’t know already there is a really cool feature in Studio 5000 Logix Designer called User-Defined Tags (UDT). This feature allows you to create “bundled” tags into one tag and then reference each of the bundled tags as members of the single main tag.
