Hi

As from TIA V19, it is possible to assign dynamic values to the names of variables passed as an interface in the Faceplates call.

This feature enables the “multiplex” faceplate interface dynamically in runtime and could be used as a similar feature as the tag prefix of WinCC Professional / WinCC V8.

TIPs

• The dynamic configuration is made on the faceplate call, Properties >Miscellaneous >  Interface > Interface name >  column “Dynamization” change “None” to “Tag Parameter”; in the right side (split window) configure the “Dynamic tag name”.
• The variable name could be a mix of fixed values and (string) tag values.
• As from the window description:

“

Defines a tag name which is composed of static parts and tag references. The resulting tag name is determined in runtime by replacing the tag references with the current tag values. Tag references must be encapsulated by single quotation marks (‘).

Examples:

1.  ‘UnitTag’.’MotorTag’.Temperature

2. Section[‘SectionNumber’].Conveyor2.Speed

“
