Integrating own application knowledge by means of VBScript and ActiveX Controls

With the help of VBScript the PLC can be relieved. Signals for displaying measured values and data are conditioned by a script.

Different script types are supported:

• Global scripts - executed in each visualization cycle
• Local scripts - triggered by actions, such as left clicking a button 
• Converter scripts - used for converting variable values 
• Limiter scripts - intended to limit variable values 
• Formulas - used to manipulate visualization objects. Access functions make it possible to change, for example, the object position or size

ActiveX Controls can be inserted as objects into visualization screens, connected to variables via their own interfaces or programmed using scripts.
