You can change the response speed of all the mappings by changing the interval time in project properties. 

Subscription Mode

Change: When the value of the mapped symbol changes

Poll: Check the mapped symbol value cyclically even where there is no change

Setting the interval speed to a very low value might cause some heavy workload between the server and the client when you have numerous mapped symbols. Instead of setting the project interval time to a very low value, you can set the interval time individually for the tags which need to be updated very often.

Create the data binding.

Expand the settings tab. Set the interval and subscription mode for the mapped symbol.
