nstojko Posts: 8 Rating: (0)	Hello! I have a problem with establishing direct connection between WinCC RT Advanced and S7-1200. My OS is Windows 7 Professional. I'm using TIA Portal v11 and I have installed Simatic NET v8.1+SP1. The main problem is that when I want to "Configure PC station online" to establish a connection I can't access the PC station of the target computer. It says that it is locked. Also, when I want to add a module in the Station Configurator it says that it can't be done due to a local S7 connection configuration with COML S7. In attachment You can find some screenshots that discribe the problem. In the HW configuration the PC station and the PC on which I want to run the runtime are the same machine and therefore I assigned the same IP address for both. The name of the PC station and the PC are identical. Both "allow" check boxes are selected in the "Security" menu of the "Configuration Console". Commissioning the drive over the Watch tabel and without the WinCC RT Advanced is working just fine. Could anyone help me to solve this problem?

Yesterday I've made the same only for S7-300 virtual PLC. Everything works just fine. Now I don't even know what to suggest you. Try to make configuration without any station configurator, just put your PC in the same subnet as PLC. it can't be any issues here. Works just simply.

My goal is to control and commision the drive over the WinCC RT Advanced. The RT by itself is working just fine, but when I want to read or write to a tag I can't because I don't have any connection to the PLC. To make this connection I must go to "Configure PC Station online". When I want to do this it says that the target PC station is locked.

Now I understand it clearly, but have not much advices. On the cases like your it would be better to sit near this computer, but lets hope other users can help.

Unfortunatelly I can't help much as I don't have Simatic net, but can you try to generate XDB file from TIA and import it into station configurator. Maybe then station will not be locked ?

Never had such problems. I advice to wait a little bit here for other users to respond. If not, you can always try to open Support Request

nstojko Posts: 8 Rating: (0)	Sorry, my mistake. I couldn't generate the XDB file because I tried to save it to a write protected folder. Anyway, I can generate the XDB file but i can't add it to the Station Configurator because of the problem discribed earlier (screenshot in attachment).
