Value
A read-write connection. Assign a tag to this connection. The application writes the value corresponding to the new state to the tag’s data source. If the Next state based on option (in the General tab) is set to Value connection, the application reads this tag to determine which state to show next.
Indicator
A read connection. You can assign a tag or an expression to this connection. The application reads the value of the connection at the data source, and updates the object’s display to reflect the state corresponding to the value.
If you assign an expression, the application calculates the value of the expression and updates the object’s display to reflect the state corresponding to the value.
If you assign this connection, the button does not show the current state until it receives a response from the Indicator connection. If you do not assign this connection, the button's state corresponds to the value at the Value connection.
Tip: |
To provide visual feedback that the Value connection has been written to the data source, assign different tags to the Value and Indicator connections. Configure the data source to pass the Value connection’s value to the Indicator connection. |
