Derived Data Types

ClearSCADA supports derived data types for use in ST programs (and Function Block Diagrams that include ST programs). The derived data types are designed to make it easier for you to read and write structured text programs—they allow you to name and group values that are used by your ST programs.

This section explains:

• Using Derived Data Types to Create Names for Types of Value.
• Using Structured Data Types to Group Internal Values.
• Using Enumerated Data Types to Create Names for State Values.
• Arrays
• Vectors.
