WinCC Professional V13 SP1 – Simple Sample: Screen change via controller

“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:

Many applications demands that the controller select (change) the HMI operation screen.

WinCC could call scripts triggered by tag change. It makes possible, for example, to call a script (indirectly) by a PLC command and use it to select (change) a screen.

Note: in this example, the trigger tag and the screen name tag are defined as internal tag, instead of PLC tag to simplify the simulations.

Requirements:

WinCC Professional V13 SP1.

Configuration main steps:

• Create a Project

• Create two tags (one for the picture name definition, “HMI_Tag_1” as String and other one as change picture trigger, “HMI_Tag_2” as bool).

• Create a scheduled task (Project tree → WinCC Professional Runtime → Scheduled task → <Add new>; Properties → General → Start time: Trigger = Tag Trigger; Tag = “Trigger” / Properties → Events → VB Script

• Configure the VB Script as follow:

Function Action()

ActivateScreen (SmartTags("ScreenName").Value), 0

Action = 0

End Function

• In PLC:

  • Set a value to “ScreenName” corresponding to the desired screen

  • Change the value of “Trigger” (invert it).

  • Note: in the simple sample project the settings are done by HMI button.
