Referring to array variables

Each entry of an array is referred to by an index. You can extract individual variables (from the array) by specifying the tag name and index:

<Tag Name>[Index]

For example, to refer to the third variable of the array in the above example (Conveyor 3), use the following syntax:

Variable Tag


The index of the first entry of an array is always 0 (zero). In this example, Conveyor_Speed[0] is the first entry of the array (Conveyor 1), and Conveyor_Speed[4] is the last entry (Conveyor 5).

Note the following when using arrays:
