Example: Use a symbol indicator
In this example, the symbol indicator monitors the Indicator connection to show the mode of operation of a blower. The blower can operate manually or automatically, or it can be turned off.
- Create a symbol indicator with the colors "red" for State 0, "yellow" for State 1, and "green" for State 2.
The application reads the tag you assign to the Indicator connection and updates the indicator’s state when the value changes. This state change enables the current operation mode to be shown.
