Hi,

sorry for missing the rules for forum posts.
My issue is already gone. The cause was a conflict of ip addresses or that the ids containing white spaces.

Best regards

Hello,
what do you mean by

"But when i try to connect to my Siemens S7 PLC it doesn't work. "?


Are you getting an error, and if so, where (at which moment and how), what is the message and other details? Please follow the rules outlined here: www.opclabs.com/forum/announcements12/2365-rules-for-forum-posts .

Regarding the log entry, I do not see any problem with it as such. Each server can have multiple endpoints, and only one can be selected for the actual communication. In the first case, the server has one endpoint, and it gets selected. In the second case, there are 5 endpoints, and the first one is chosen. The "EligibleNotAccepted" only indicates that those are endpoints that *could* have been selected, but basically had a "bad luck" (in this case, most likely because they are secure endpoints, and the default endpoint selection prefers non-secure connections).

Best regards

Hey,

i'm using QuickOPC 2017.2 with COM-Interface to Delphi 2010.

When I try to connect to my open62541 server everything works fine. The log says:
..
ClientConfigurationEventHandler: Information(2001): OPC-UA endpoint selection on discovery URL "opc.tcp://localhost:48420" candidate report (1 entries) follows.
[0:Winner(1000+0)].
...

But when i try to connect to my Siemens S7 PLC it doesn't work. The log says:
...
ClientConfigurationEventHandler: Information(2001): OPC-UA endpoint selection on discovery URL "opc.tcp://192.168.3.150:4840" candidate report (5 entries) follows.
[0:Winner(1000+0), 1:EligibleNotAccepted(60), 2:EligibleNotAccepted(110), 3:EligibleNotAccepted(65), 4:EligibleNotAccepted(115)].
...

Do you have any idea?
Thanks.
