Codesys structure array. A structure is a user-defined data type, which combines multiple variables of any data type into a logical unit. In this video, you will learn how to declare, initialize and use an array variable in Codesys with Structured Text as the programming language. You need somewhere to update the Daten array "data" to match the input variables that are defined in your function block call or initialization. This driver has partial support for the arrays that can be defined in a PLC.

To my knowledge you can't selectively initialize individual array elements as you are maybe wanting to do. Both one- and two-dimensional arrays are supported for all types, except Strings and Structures.
