Hi,

As of TIA V18, new resources are available that make it possible to customize the operation of recipes, that is, to handle them without using the parameter set control directly.

One of these features are new system functions:

• CreateParameterSet
• SaveParameterSet
• LoadParameterSet
• DeleteParameterSet
• RenameParameterSet
• ReadParameterSet
• WriteParameterSet
• ReadParameterSetName
• RenameParameterSet

• 
  

Tips:

• Part of these functions exchange data between intermediate variables, in general, with internal tags. These variables must come from a data structure similar to the PLC data type and must be declared in the Edit Tag property of the Parameter Set Type.

Other features are new Parameter control view properties: CurrentParameterSetTypeID and CurrentParameterSerID. With these parameters it is possible to monitor the actual parameter set / parameter set type selected in the control.

Tips:

• If you link these properties to tag, uncheck the “Read only” checkbox to allow external access.

Additionally you have new script functions to get the name from the Parameter Set ID / Parameter Set Type ID: GetParameterSetIDName / GetParmeterSetTypeName.

Tips:

• To link the script function outputs to HMI tags use “HMIRuntime.Tags.SysFct.CreateSetTagCommand(“tag name”)” as parameter.

• The name showed is the “Display name” parameter of the Parameter Set type (not the “name”)

Sample project 

Hello Mr Denilson Pegaia,

I downloaded the "Project30" I want to apply the
"ScreentParameterSetSystemFunction18A" screen by setting local HMI variables
and then saving them in the recipe and when I need to download these parameters
to the PLC, I noticed that it is necessary to use several UDTs that have the same
structure as the which was declared to write the recipe. I did these steps, but
when I enter the variable in the "Edit tag" field an error appears "The Edit tag
InternalTagProduction has to be Session local."
How do I resolve this error?
