Indicators
This chapter tells you about:
•
the different types of Indicators
•
how to configure each Indicator
You can create these two types of Indicators:
•
Multistate Indicator
•
List Indicator
Indicators do not retain their values when the terminal is turned off.
The Multistate Indicator is a display object that enables the operator
to display the state of a PLC operation on the screen.
You can use the Multistate Indicator for various purposes. For
example, create a Multistate Indicator that is only two pixels high to
simulate flow in a pipe or indicate the motion of an object. Use a
two-state solid rectangle to simulate an indicator light, add
descriptive text to the object, or add a graphic image. Or, use a
Multistate Indicator to hide text until it is needed or becomes
applicable.
You can configure the state values of Multistate Indicator objects. At
runtime, the object displays the state whose value matches the
Indicator State control value.
Note: If the Indicator State control contains a value that does not
match any of the Multistate Indicator’s assigned state values, an error
state occurs and the highest numbered state is displayed without its
label. An error state also occurs if the Indicator State control is not
assigned. In this case also, the highest numbered state is displayed
without its label.
Tip: If you plan to use the same graphic image for each state, use a
Symbol instead of a Multistate Indicator. You can configure the
Symbol to display different colors or blink attributes for different
states, and the Symbol uses less memory. PanelView also processes
the information more quickly for Symbols than for Multistate
Indicators. For more information, see Symbols, later in this manual.
