Dear Experts,

I never use parameter in VB Scripts of wincc comfort panel.

How to use VB Scripts parameter in TIA Wincc comfort panel ?

What is the purpose of this parameter ?

Best Regards,

Vorapob

Hello vorapob,

with a parameter "ByVal" you can pass a constant or the value of an HMI-tag to the script.

Parameter "ByRef" is e.g. discussed in Can I pass a parameter to a script by reference (ByRef)?.

After that How can I do please give me for example?

Vorapob,

you can search for WinCC Engineering Programming Reference for more information about scripts.

Sub MySub (ByVal MyModeAppend)

Dim f

Set f = CreateObject("FileCtl.File")

f.Open "\Storage Card\testfile.txt",MyModeAppend

f.Close

End Sub
