52.22.5 Sequence
This control structure formally defines a sequence of activities as a unit, allowing it to be treated as such. (For example, the entire sequence can be enabled or disabled in a single action, as exemplified in section "Sequences".)
- Allowed Equipment: Select one of the following:
Any equipment is allowed: Any equipment is allowed.Only distinct equipment is allowed: Only one single equipment is allowed in the sequence (specified in the first script action included in the sequence).
Example:
[Activity1, Activity2, Activity3]
[EQ1, EQ1, EQ1] = OK
[EQ1, EQ2, EQ1] = Not OK
[EQ2, EQ2, EQ2] = OKOnly selected equipment is allowed: Specify which equipment(s) to allow in the Equipment property.
- Equipment: Specify which equipment(s) to allow.
The validation is recursive, so it allows for nesting of sequence activities. The user is not allowed to make the scope more inclusive. e.g. it will not work to have a sequence activity that only permits EQ1 and EQ2 to contain a sequence activity that permits EQ3, this construct will cause the validation for the first sequence activity to fail if the second activity contains any activity which targets EQ3.
