When parameter is added to the flowsheet for the first time, the selected frequency is set as a default value. 

You are able to change the default frequency of a parameter even if it has been already set up. To do it, please follow these steps:

1. Open a parameter and click on the Lock icon to unlock the parameter's settings:

2. Select required frequency from the Continue every (hours) drop-down list:

3. Finally, to lock your changes, click on the Lock icon and then on Done:

NOTE: You can skip pressing the Lock icon as the parameter's highlighting gets automatically locked after it's saved.

After the frequency is changed and saved, you will notice that the highlighting of the parameter has been changed as well.
