UDS 4.0.3.10, RSLinks 2.54 Classic Professional

[Former Member]

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.

Not quite, Jeremy. Becasue we were in a hurry to have a system running we dropped the RSLINX OPC configuration for the moment and installed Kepware OPC instead. Using DA3, it looks like all the tags can be at least browsed. We're still having some issues with BIT type tags (true/false highlighted in RED in the UDS alias list) but I guess it'll be "all white" when we'll convert them all to integer type.

We'll come back to the RSLINX approach a little later (during weeks 3 and 4 in March 2009 I suppose).

Many thanks,

Paul.

You are correct a 0/1 Integer will work very well for your bit fields.

A small update ..

I updated the UDS to version 4.0.3.20, I am able to see the OPC data from RSLinx in Excel using COM i.e. =RSLinx|OPCData!C1Temperature

Same issue though when UDS browsing in alias configuration ..

Thanks,

paul.

Did the resolution that I provided for Amy also solve your issues?
