ArrayInfo is a built-in function in CODESYS that provides information about an array. It takes two arguments: the array and the type of information requested.
The type of information that can be requested includes:
- Number of elements in the array
- Size of each element in the array
- Total size of the array in bytes
Here's an example of how to use the ArrayInfo function in CODESYS:
```
VAR
myArray: ARRAY[1..10] OF INT;
numElements: INT;
elementSize: INT;
totalSize: INT;
END_VAR
numElements := ArrayInfo(myArray, 1);
elementSize := ArrayInfo(myArray, 2);
totalSize := ArrayInfo(myArray, 3);
```
In this example, we declare an array `myArray` with 10 elements of type `INT`. We then use the ArrayInfo function to get information about the array and store it in variables `numElements`, `elementSize`, and `totalSize`.
Note that the second argument to the ArrayInfo function specifies what type of information we want. In this case, we request the number of elements, size of each element, and total size of the array.
