starcraff Posts: 8 Rating: (1)	I Have installed the WinCC v 6.0 SP3 to Windows XP Pro SP2 (Install to Dell Inspiron 6400that comes with Broadcom 440x 10/100 Integrated Controller). Network settings should be OK because could see other PCs in the workgroup,surf internet and couldping the PLC CPU. I Have install all the required e.g. Messege Queing (common component), SQL Server WinCC, WinCC and all network protocols are intact following the manual. WinCC runtime could be displayed but there is no sign data display even if the network is active. I have installed on another PCsystem with the same setting and procedures and the WinCC runtime could display the life data without problem on the very same network setup (cable and everything) Currently scaled down the problem to the notebook. All software firewall, AV firewall is already deactivated. Kindly assist. BR, star

Has this been set correctly in the PG-PC interface? Apologies if I have misunderstood your problem. Salma

It sounds to me like Softnet has not been installed / configured. If you are not familiar with Softnet - to use a standard network card to communicate to your PLC you need to install Softnet which allows WinCC to see the card as a comms card. If you have purchased WinCC V6 SP3 (and not upgraded) then you will have received a licence for Softnet Lean allowing you to connect to up to 8 PLCs. You should install this licence and also the Simatic Net CD which will give you the corresponding drivers. Is this of any use?

If you do not have hotfix 2 then you can download it from http://support.automation.siemens.com/WW/view/en/21480479 Regards, Salma

Filo Posts: 54 Rating: (2)	I'm not quiet sure what is your problem, but I'll try to give you some directions. In SP2 Microsoft has made some serious changes about the COM/ DCOM security. Thats why I use Windwos XP Pro SP1. If your stuck with SP2 try to give rights of the Evryone group to acess the COM interface.

starcraff Posts: 8 Rating: (1)	To Salma, How do I check whether Softnet is properly installed? As for the Simatic Net CD, the CD would not run because the system noted that OS is of XP Pro SP2. The installer does not support this OS version. However, I've repeated the installation with the other PC (which is install to install MS SQL WinCC,WinCCand finally followed by Step 7) and the communication works fine. The other PC is also by default XP SP2(Slipstream), which means by default, we cannot go back to XP SP1 because SP2 is already integrated into the OS). The hotfix is already installed because the Simatic version is Simatic WinCC V6.0 SP3 incl. HF2. To Filo Currently, thePC is working in a basic workgroup and not merged to domain. The user is by default a computer administrator. How do I give rights of the Evryone group to acess the COM interface? To rule outcorruption in devices and installation, I've clean install the OS and walked through the installation process all over again. However, the COM failed. Please help. Thanks star

I did some hunting on the support site. WinCC V6 SP3 hf2 needs Simatic Net 2005 hf1 to work on XP SP2. The following two faqs contain this information: · http://support.automation.siemens.com/WW/view/en/21980615 · http://support.automation.siemens.com/WW/view/en/21927774 Can you please download Simatic Net 2005 hotfix 1 from http://support.automation.siemens.com/WW/view/en/12660737 This should hopefully get your communications working on your laptop. Can you please let us know how you get on. Regards, Salma

starcraff Posts: 8 Rating: (1)	Dear Salma and all Basically, it is OK without the Simatic Net because the system has downloaded the required COM component after installing the Step 7 software. My issue was purely hardware. It seems that the Broadcom 440x 10/100 Integrated Network controller on the Dell Inspironis not compatible with the PLC system. Even though the network adapter could enable the notebook to see the other members of the Windows workgroup, it could not receive/decipher the data dump from the PLC system. I used a normal the USB network adapter, redirect the network path to the USB network adapterand everything worked fine. Anyway, I thank you for your kind assistance and I believe a lot of people would benefit the tip on the Simatic Net. By installing WinCC on its own without Step 7, the PLC-PC interface will definately not take place. Thank you again. star
