Hello All,
I have some problems with the UDS, not getting any tag names or data from the PLC when browsing (UDS Alias) . However, the tag groups are visible.
Overall there are only 112 tags in the project, so I guess it's not a limitation. IMHO looks very similar with Amy's problem.
The logs say:
[01/15/2009-14:05:15.672] DataOPC [P:2832, T:3492, UDS, INFO] 0x0 Reading Items. [tagUtil/lhds2BrowseThread.h @ 172, lhds::BrowsingThread::DoBrowse] ********** Start of Exception Stack Trace ********** 1) [01/15/2009-14:05:15.688] DataOPC [P:2832, T:3492, UDS, ] 0x0 HRESULT: 0x80010105 [The server threw an exception.] [core/lhdsFwkThrowHelpers.h @ 111, lhds::_lhds_rethrow_helper] 2) [01/15/2009-14:05:15.688] DataOPC [P:2832, T:3492, UDS, RETHROW] 0x0 Rethrowing exception.

[tagUtil/lhds2Connection.h @ 1160, lhds::LHDSConnectionImpl <class CLHOpcDaConnection>::DoReadTags] ************** End of Exception Trace **************
then, a whole set of these Exception traces, one for each tag group. The configuration parameters follow.
