Husam Posts: 101 Rating: (11)	Hello I wonder if there is a tutorial that helps me write a VB code in the WinCC 6 Editor that will allow me to read and write to the serial port, without using a PLC> ??!! Explanation: i am a university student, conduction a project.. the PLC is located 10 Km away from my PC on which i have WinCC 6 installed on. I could successfully establish RF communication between my PC and the PLC. NOW, how can i read from the serial port, and update the tags in WinCC 6 directly using VB ? Your assistance is highly appreciated. Regards, Husam Othman.

Hi Husam,

for serial communication I´d suggest a WinCC Addon:

http://www.industry.siemens.de/itps/it4industry/en/wincc/index1503863.htm

"......

Serial Communication in WinCC with the WinCC Serial Communication DLL

The WinCC Serial Communication DLL provides functions for communication with end-devices via the serial interface of a WinCC-PC. By supporting multiple interfaces and asynchronous communication, the DLL is also suitable for demanding communication requirements

We have lots of customers in the UK using Omniserver with WinCC to talk to third party devices via RS-232, TCP/IP, etc. A demo version of Omniserver can be downloaded from http://www.omnidssi.com and may be a simple cheap alternative. You could write scripts in VB but why reinvent the wheel !

Nemo Posts: 3149 Rating: (171)	Hi Husam, well, the dll is a product of its own...and unfortunately not for free. => but perhaps, you can get a special discount, a kind of trial license or a "real" license, if you are telling the WinCC Competence Center in Stuttgart, that you need it for your thesis [;)] Good luck, Nemo

Reuben Posts: 70 Rating: (13)	Hi I wrote a simple DLL long ago for use with WinCC for serial communications. You can download it for free off my website: http://www.allottware.co.za/raweb.dll/Page?n=downloads_unfiled It is not suitable for continuous, asynchronous communications, as you must use C-script functions (sorry no VB!) to read and write data (all the required C-script wrapper functions are included in the download). It is suitable for things like Scales, Barcode scanners, Printers etc. Reuben

Husam Posts: 101 Rating: (11)	Hello Special Thanks to Reubenfor providing me with his serial comm dll, i really appreciate it much. however, I am in the process of implementing my own Serial Communication DLL using VB.NET. Ifi succeed, and hope i will, can i then use it or import it to the VBScript Editor of WinCC 6? what is the command to do so? Kind Regards, Husam Othman.

Captain Chaos Posts: 3 Rating: (1)	Hi Husam, well, I think including a dll isn´t a WinCC specific topic. at Google you will certainly find some examples (look for "dll vbs programming") http://www.freevbcode.com/ShowCode.asp?ID=7520 Happy New Year, Captain Chaos
