fbelic Posts: 327 Rating: (28)	Greetings What you posted is a Visual Basic, not VB Script. Although you could use this code to build an external program a mentioned in previous post. I would reccomend some newer version, though. Best regards

This script works so perfectly... today only i have developed it & tested & found working perfectly with WinCC Flexible 2008 SP2 PC Runtime. Dim SMSSend Dim SMS Dim buffer, DAM_FT, DAM_INCH DAM_FT=(POND_WATER_DISPLAY) DAM_INCH=(Inch_Value) ' This is the name of the MSComm Control Dim S Dim NoArr(6) 'here you can add all the cell numbers you want to send to Set SMSSend = CreateObject("MSCommLib.MSComm") If ( NO1_MOBILE_INT=15 ) Then NoArr(0)=MOBILE_NO_1 End If If ( NO2_MOBILE_INT=15 ) Then NoArr(1)=MOBILE_NO_2 End If If ( NO3_MOBILE_INT=15 ) Then NoArr(2)=MOBILE_NO_3 End If If ( NO4_MOBILE_INT=15 ) Then NoArr(3)=MOBILE_NO_4 End If If ( NO5_MOBILE_INT=15 ) Then NoArr(4)=MOBILE_NO_5 End If If ( NO6_MOBILE_INT=15 ) Then NoArr(5)=MOBILE_NO_6 End If For S = 0 To 5 SMSSend.CommPort = 1 SMSSend.Settings = "9600,N,8,1" SMSSend.InputLen = 0 SMSSend.Handshaking = 0 SMSSend.PortOpen = True SMS="VASANA BARRAGE WATER STORAGE CURRENT LEVEL IS " INCREMENT_VALUE=INCREMENT_VALUE+1 If INCREMENT_VALUE = 10 Then SMSSend.Output = "AT" & Chr(13) End If 'Do 'buffer = buffer & SMSSend.Input 'Loop Until InStr(buffer, "OK") 'buffer = "" If INCREMENT_VALUE=12 Then SMSSend.Output = "AT+CMGF=1" & Chr(13) 'Do 'buffer = buffer & SMSSend.Input 'Loop Until InStr(buffer, "OK") 'buffer = "" End If If INCREMENT_VALUE=14 Then SMSSend.Output = "AT+CMGS=" & Chr(34)& NoArr(S) & Chr(34) & Chr(13) '& Len(SMS) / 2 & Chr$(13) End If 'Do 'buffer = buffer & SMSSend.Input 'Loop Until InStr(buffer, ">") 'buffer = "" If INCREMENT_VALUE =15 Then SMSSend.Output = SMS & DAM_FT & " Ft " & DAM_INCH & " Inch " + Chr(26) INCREMENT_VALUE=0 End If 'Do 'buffer = buffer & SMSSend.Input 'Loop Until InStr(buffer, "OK") ' try to force sends by closing the ports and reopen in loop SMSSend.PortOpen = False Next

fbelic Posts: 327 Rating: (28)	Greetings Looks like you are right; I couldn't completely test it because I don't have serial port on this laptop, but it didn't report any errors during execution. Thanks for the tip! Best regards

bezz Posts: 2 Rating: (0)	Dear friend, I tried Your script, but there was an unknown error at row: Set SMSSend = CreateObject("MSCommLib.MSComm") I found that the object is in MSComm32.ocx file. I got the file, I loaded MSComm32.ocx file into WinCC flexible, but still not working. What do I have to do to run the script correctly? In which file is the "MSCommLib.MSComm" object? How must I install it into WinCC flexible? I found that the MSComm32.ocx file is licenced. Is the problem in the licence? Where can I get that licence? How can I install it? Thanks for reply.

projects.jaydeep Experienced Member Joined: 6/4/2008 Last visit: 10/2/2025 Posts: 58 Rating: (1)	dear bezz, Your problem is correct. i have got 3 laptops, amongs which this script only works with one laptop. i also have tried so many times in various 10 other desktop pcs but still this things doesnt work with wincc flexible 2008. SO i have contacted siemens germeny & they said the activx support for WinCC Flexible require tremendous execution time so it will not work on this mscomm32.ocx activx files. So instead of using Wincc flexi script you need to use some thirdparty softwares. Thanks & regards Jaydeep
