But if the data type is ARRAY, users cannot import ARRAY for n value is 65535. (For DVPxxMC/ AS5xx series, the maximum for n value is2147483647.) If the member again. The system supports multi-dimensional array, up to three-dimension. The format of a two-dimensional array is ARRAY [ 0 .. n ] [ 0 .. n ] OF and the three-dimensional array is ARRAY [ 0 .. n ] [ 0 .. n ] [ 0 .. n ] OF .
As the image shown below: The naming rules of user-defined names and member names are stated as below. A user-defined name cannot be the same as names of other user-defined data types.
