UDS 4.0.3.10, RSLinks 2.54 Classic Professional

53 Views

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]

then, a whole set of these Exception traces, one for each tag group. The configuration parameters follow.
