Some Forms in ClearSCADA use array fields. These are single fields that can contain zero, one or more values in a sequence, with each value being referred to as an ‘element’. For example, on the User Form, the User Groups field is an array field - a single field that allows you to associate the User with zero, one, or multiple User Groups as required. Each selected User Group is an ‘element’ of the array field’s value.
For information on how to use an array field on a Form, refer to the following sections:
- Add an Element to an Array Field
- Remove a Single Element from an Array Field
- Remove Multiple Elements from an Array Field
- Edit an Element in an Array Field
- Go To the Display for an Element in an Array Field
- Display a List of Configuration Changes for an Array Field.
NOTE: Each element of the array can be accessed individually. To support this, an index is used, which numbers each element from 0 to n-1, where n is the total number of elements in the array. The first element in the array has an index of 0, the second element an index of 1, the third an index of 2 and so on.
