Hi,

I am facing a similar problem. When I try to download a PC Station I get a warning saying that the versions are different (offline/online). In the HW catalog of my project I don't see an older version of OPC Server, I only have one option which is v13.0.

In the target PC Station I installed the OPC Server DA that is inside the Tool folder during the installation wizard.

I am using in my configuration station TIA Portal v13+SP1+Upd5 (Step7 Pro and WinCC Pro) and in the side of the PC Station WinCC Professional Runtime v13+SP1+Upd5.

Hope someone can help.

Ty.

hi,

I think the station was loaded before with TIA V12. and you have TIA V13.

Hello,

can you check the installed OPC Component in the PCStation?
The system detect that online is a Version V12 existing.

What have you exactly installed on the PC Station?

You see no drop down on OPC Server in your TIA?

Hi, Thanks for the answer. I was the problem...is working ok. I am used to do this with Step7 classic and in there inside the OPC Server folder you have different versions but in TIA is different. I didn't look under Info, the Info Window was closed....any way....my bad.
