It works when i use a digital tag in properties, but i want to use a script to this, per example, when the value is higher then 9,8 shows the indicator red... I'm new in the JS world I tried this code export function Gauge_3_NormalRangeColor_Trigger(item) { var value; return value; let gauge = dummy_real if (gauge > 9.8) { ProcessValueIndicatorBackColor = HMIRuntime.Math.RGB(255, 255, 255, 255); } else { ProcessValueIndicatorBackColor = HMIRuntime.Math.RGB(255, 0, 0, 255); } return gauge; } but not worked. any ideas?

For more information, please see the following links. Training Manual/Document for learning VB Scripting in WinCC Library VBScript WinCC Change bg color via Dynamic VBS script Of course, I think( return value;) in the second line is problematic, but I'm not sure it should be compiled and tested This is an example: Dim Obj, pdf , msg , ret item.Enabled = False Set Obj = CreateObject("VBScriptLibraryWinCC.dll") HMIRuntime.Trace "Start: " & Obj.GetDateTime() & vbNewline pdf = "<head><style>.test { background-color: linen;color: maroon;}</style></head>" _ & " <body Class=""test""><p><h1>Hello PLC HMI SCADAS</h1>This is html generated with HtmlRenderer.PdfSharp and rendered text with css and image.</p>" _ & " <p><img src=""https://plc-hmi-scadas.com/images/header1280.gif"" height=""100%"" width=""100%""></p>" _ & " </body>" ret = Obj.GeneratePdf(pdf , "C:\\PDF\\CodeHTML2PDF_2.pdf",msg) If ret = -1 Then HMIRuntime.Trace "Error: " & msg & vbNewline End If HMIRuntime.Trace "Finished: " & Obj.GetDateTime() & vbNewline item.Enabled = True

" WinCC Unified uses JavaScripting as scripting language. It is different as the scripting language of the WinCC Basic/Confort/Advanced/Professional (VB, C) and it is natural that the user needs some helps to changes the mindset to the new language.

Try to use this script: export function Gauge_1_ProcessValueIndicatorForeColor_Trigger(item) { var value; if (Tags("rAux").Read() > 9.8) { value = HMIRuntime.Math.RGB(255, 255, 255, 255); } else { value = HMIRuntime.Math.RGB(255, 0, 0, 255); } return value; } rAux is internal HMI Tag and also Trigger for this script.
