In the process of PLC programming, if there is a lot of data, we have to use some complex data types to improve our efficiency, so what are the complex data types? How do we use them? ...... 

First of all, let's know what they mean. Arrays are composed of the same type of data, which can be composed of multiple dimensions, up to 6 dimensions; and the structure can be composed of different data types, such as basic data types, complex data types, and user- defined data types, and structures and arrays can be nested in the structure. As shown in the figure below: 

We can define it in the variable declaration table of logical blocks, such as organization blocks, or in the data block DB.
