Some Forms in ClearSCADA have 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.
The topics in this section explain how to use an array field on a Form. For more information, see the topics that are listed in the gray footer section at the bottom of this topic. Select the relevant entry to display the topic that you require.
Each element of an 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.
