6.6 List Data Points
List data points are a special category. In contrast to other data points, list data
points generally have more than one associated value element. This category
includes tripping matrices, programmable logic functions, and event logs. When
a list data point is selected, the symbol ‘↓‘ is displayed in the bottom line of the
LCD, indicating that a sub-level is situated below this displayed level. The
individual value elements of a list data point are found at this sub-level. In the
case of a list parameter, the individual value elements are linked by operators
such as “OR”.
