WinCC Unified - Simple sample - activating an object button externally.

“Simple Samples” are small projects that demonstrate simple features. The target is give a quick overview about the theme and be used as start point for related discussions. Follow there are a short description and the configuration main steps.

Description:

In this simple sample, trend “first record” Button is activated by an external Button with help of script / system function (SetPropertyValue). The principle of activating object button by script could be adapted to other controls, like alarms and trends.

TIP:

The main point here is to get access to the button visible property.

The buttons are referend by an index and not by his name (the index stay on the property column Name, and the description in the column Static value). To get the right name, click with the right mouse button on the object property (here in Miscellaneous, Toolbar, Elements [0] Button, visibility) and choose “copy property name”. Use this reference in the SetPropertyValue system function (or equivalent script)
