WinCC Unified: Handle Parameter Sets without using the ParamterSet Control

 Hi, thank you very much for all your posts, they were very helpful.

Rigth now I´m working with Parameter Sets on TIA V19 and I´m facing a big problem.

I want to handle Parameter Sets without using the ParamterSet Control and for that I´m trying to use Edit Tag property of the Parameter Set Type. The problem is that the PLCUDT that I´m using in the Parameter Set Type has other PLCUDT inside (This help me to have better data structure and better data handling in the PLC) but I can´t create a HMIUDT with the same structure than the PLCUDT. 

This is very disappointing because the only solution I have thougth is that I´m gonna have to create a very simple PLCUDT with a bounch of data and this will make me have to handle data in a more complex way. I think the use of UDT´s in Parameter Sets has a very big potencial and eficiency, but this this problem is a step backwards of using UDT´s for Parameter Sets.

Do you have any suggestion?

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”)

Hello AutoGen,

I have exactly the same problem...

Have you got news about this? Have you found a better solution instead of making a simple PLCUDT like you said ?

The system is very complex for very uncomplex objets that PLCUDTs must be...

i have a PLCUDT with 4 variables, coresponding to one device

i have a PLCUDT with 10 of this PLCUDT to manage recipes (parameter set) of eachs devices in one time

But like you, i cant make a HMIUDT with the same structure...

so i cant link an edit tag and with this type of multi-PLCUDT structure i am forced to use parameter set control or to """""simplify""""" my plcudt...

hope you got news

have a good day

Hi AutoGen_2787469,

According to MBerghauser's post in an older topic, it is possible by putting the PLC UDT into the project library.

Can you let me know if that works?

Hi MindFlayer,

i am Autogen_2509766 (idk if my nickname will show, first times i interact in the forum)

According toMBerghauser's postin an older topic, it is possible by putting the PLC UDT into the project library.

Yes in the library you can put PLCUDT and HMIUDT.

but the edit tag of the parameter set MUST be an internal scope HMIUDT based tag.

The HMIUDT used for edit tag must have the same structure as the PLCUDT.

But you cant put HMIUDT inside HMIUDT (you can put PLCUDT inside PLCUDT)

This is the problem

Have a good day 

HI Autogen_2509766,

I did a test and I am able to select a PLC UDT with nested UDTs. See screenshot below. The PLC UDT is in my project library as a PLC UDT (not as an HMI UDT).

Yes you can use PLCUDT as parameter set Data type but not as Edit tag.

You cant replicate the "Master V2.6.0" structure in a HMIUDT for edit tag

Have a good day 

Hi AutoGen_2509766,

Now I understand your problem. I think it's best to create an SR. Afterwards, can you post what they said please?

 Hello Murof,

Murof

I also struggled with this issue in some projects.

 So what did you do with this problem? have you got tips ?

Murof

-> I have no idea if there is something new upcoming in V20, perhaps someone else do already

known

 I really hope this will change in upd3 or V20...

I'm curently in support request with Siemens about this topic so i will inform here if i have news..

Have a good day !
