Gabriel_Rabelo Posts: 42 Rating: (10)	You´ll need to set tags as objects in VBS, like this: 'Variables declaration DimstrTag1 Dim strTag2 Dim strTag3 Dim strConc 'Setting tags to be read Set strTag1 =HMIRuntime.Tags("FIRST_TAG_NAME") Set strTag2 =HMIRuntime.Tags("SECOND_TAG_NAME") Set strTag3 =HMIRuntime.Tags("CONCATENATE_TAG_NAME") 'Read tag values strTag1.read strTag2.read 'String concatenation strConc = strTag1.value & strTag2.value strTag3.value = strConc strTag3.write

Radastan Posts: 56 Rating: (8)	If I try to concatenate 3 or more tags the script hang (and WinCC runtime too). ¿Any idea? [code]char td_text; char td_text2; td_text = GetTagChar ("@NOTP::td_text1"); td_text2 = GetTagChar ("@NOTP::td_text2"); strcat (td_texto, td_texto2); td_text2 = GetTagChar ("@NOTP::td_text3"); strcat (td_texto, td_texto2); td_text2 = GetTagChar ("@NOTP::td_text4"); strcat (td_texto, td_texto2); td_text2 = GetTagChar ("@NOTP::td_text5"); strcat (td_texto, td_texto2); SetTagCharWait("@NOTP::td_text",td_text);[/code]

Use this with printffor diagnose- use an diagnose Window so you see where the error ist: WinCC Information system > WinCC Diagnosis > Starting ApDiag.exe td_text = GetTagChar ("("@NOTP::text_1"); td_text2 = GetTagChar ("("@NOTP::text_2"); printf("\r\n td_text: %s", td_text); printf("\r\n td_text2: %s", td_text2); strcat (td_text, td_text2); printf("\r\n 1td_text: %s", td_text); td_text2 = GetTagChar ("("@NOTP::text_3"); strcat (td_text, td_text2); printf("\r\n 2td_text: %s", td_text); td_text2 = GetTagChar ("("@NOTP::text_4"); strcat (td_text, td_text2); printf("\r\n 3td_text: %s", td_text); td_text2 = GetTagChar ("("@NOTP::text_5"); strcat (td_text, td_text2); printf("\r\n 4td_text: %s", td_text); SetTagCharWait("("@NOTP::text",td_text); When this code doesn't work perhaps you should use strncat.
