A UDT allows you to create a custom data structure that mimics real-world equipment. Instead of creating loose variables for a pump's status, speed, fault, and runtime, you can define a UDT_Pump containing all these variables. When scaling up a factory floor, adding a new pump becomes as simple as declaring a new variable with your custom UDT type. Arrays and Dynamic Indexing
