Configure ActiveX control properties to read and write data

In a script, you can read data from and write data to an ActiveX control. You use the ActiveX control properties associated with specific ActiveX controls.

There are two ways of doing this:

• Use the ActiveX control property in an InTouch HMI QuickScript or ActiveX event script. The property value is read or written every time the script is executed.

• Link the ActiveX control property directly to an InTouch HMI tag or I/O reference. The property value is read or written at every update interval.
