VBS:(adopted from: http://blogs.technet.com/b/heyscriptingguy/archive/2005/06/22/how-can-i-compare-two-string-values-regardless-of-letter-case.aspx) Dim str1, str2, intCompare str1 = HMIRuntime.Tags("SCANNER_1").Read str2 = HMIRuntime.Tags("MASTER_1").Read intCompare = StrComp(str1, str2, vbTextCompare) If intCompare = 0 Then HMIRuntime.Trace "The strings are equal." & vbCrLf HMIRuntime.Tags("M700_0_1").Write 1 Else HMIRuntime.Trace "The strings are not equal." & vbCrLf End If
