When creating bar graphs, indicators and displays, consider:
•
Indicators reading a value do not have a “dead band” in which a
range of values are interpreted as a single state. For most
applications, the controller ladder logic should allow a range of
values above and/or below the specified value for each state to be
interpreted as the same state.
•
Multistate indicators support up to 2,000 states or entries
(numbered 0-1,999).
•
List indicators support up to 255 states or entries (numbered
0-254).
•
For multistate or list indicators, use only the number of states or
entries required by the application.
•
Multistate indicators include an error state (State E). The error
state notifies an operator that the data read isn’t within the
expected ranges.
