A reference client (introduced in V7) is a client station that refers to a "main" client. A single client can represent a group of clients that are identical in all respects (from the WinCC project point of view). A good example where the reference client concept comes in very handy is for identical client stations in a central control room. Instead of maintaining multiple stations in your project, you maintain one client station. The other client stations “refer” to this client (shortcut).The reference is only at project level. That means you have to download to all clients. The source program for the download is picked up from the "main" client. Actually there is only one client station program. Take a look at the folders in the project (from Windows explorer)and you'll know what I mean. So, in your case if you have 2 clients that are not identical then you should notdefine one of them as a reference client. A user authorization change has to be done on a client or a reference client. When you open the reference client, it actually opens the client station!So it is immaterial whether you open the client or the reference client to make your changes. And global changes (like graphics etc.) have to be done on the server only. Hope the concept of reference client is now clear.See attachment. Regards AttachmentDokument1.pdf (215 Downloads) |
