Additional Information
With the Sysmac Studio, the data type is expressed as ARRAY[0..2] OF WORD when an
array is specified for a data type. However, a data type of an array is simplified in this
document (e.g. WORD[3]).
It is possible to set either of the following to specify an array for a data type with the Sysmac
Studio.
•ARRAY[0..2] OF WORD
•WORD[3]
In the example above, 3 WORD array elements are secured.
