Display the Properties window for a Totalflow String Point object and then select the Control tab.
The tab displays the standard Control properties for a Geo SCADA Expert string point (see Define the Control Settings for a String Point).
If the Enabled check box is selected, you will get access to the control aggregate and you can call the Control method on the point to change a parameter’s value in the Totalflow. This is providing that the App/Array/Register for the point refers to a writable string value.
When the Control method is called from the context sensitive menu, or from a pick action without a parameter specified, Geo SCADA Expert will prompt the user for a new string value. The string is limited to 30 characters (strings with more than 30 characters are truncated). Strings have to be in ASCII format.
After calling the Control method, it is good practice to check the Event Journal (Events List) to check whether the control request was successful.
