Hello everyone,

I am currently working with WinCC Professional and wondering if there are similar functions to lpsz in WinCC Classic. In WinCC Classic, I uselpszPictureName,lpszObjectName, andlpszPropertyNameto dynamically access elements and their properties.

Are there comparable functions or methods in WinCC Professional to accomplish similar tasks? I am particularly interested in how to access pictures, clicked objects, and their properties in scripts.

I should mention that I am a beginner with WinCC Professional, so any detailed guidance or examples would be greatly appreciated. Additionally, I am particularly interested in how to access the clicked object properties in scripts.

Thank you in advance for your help!

Hello wen xuan_li49,

first of all WinCC and WinCC Professional are using the same Runtime. So the scripts accessing screen-objects are similar.

To do this via c-script you can use the funktions "GetPropXXX" and "SetPropXXX", for example:

//Set the visibility TRUE
SetPropBOOL("myScreen","IOField1","Visible",TRUE);

Instead of "myScreen" you can write “lpszPictureName”, if you are inside the same screen. This is in WinCC Professional the same as in WinCC. Here are the Links to the online documentation of these functions: SetProp / GetProp

But, it is also possible with VBS. You can address an object absolute, like this:

HMIRuntime.Screens("myScreen").ScreenItems("IOField1").Visible = 1

Or you can address an object relativly, p.e. if you have a script on a button on the same screen:

Item.Parent.ScreenItems("IOField1").Visible = 1

Here is the link to "ScreenItem"-object underneath the VBS object model: ScreenItem

Just have a look, I guess there might be other entries also interessting. But you have to be careful: The entry should be signed with "RT Professional", because not all entries are for Professional.

I hope this helps! Greetings,

Yes, Murof, you're right! The names are different in WinCC V7/8 and WinCC Professional (I forgot to mention it in my first reply). Thank you, Murof!

lpszPictureName → screenName

lpszObjectName → objectName

lpszPropertyName → propertyName

Best regards,
