I am currently using the Siemens Enhanced Driver 1.3.9, and I am having an issue where i copied my tags and udt structures from one tag provider to another and it only reads the tags partially. Using Notepad++ I changed the OPC path to a different PLC that is an exact replica of the one I have been using, just a parallel line.

The tags are set up as "Leased" with a "Rate (ms)" of 0, and a "Leased/Driven Rate (ms) of 1,000. The original tag provider works just fine, but the new one only reads a few tags here and there and the others read as "Uncertain\_LastKNownValue" the quality says ... Uncertain\_LastKnownValue("Whatever was updating this value has stopped doing so.")

I have done this on another tag provider and it worked just fine. I have 2 duplicated lines, once i got the first two unique lines working properly i duplicated the tag providers and projects. The first line i copied and pasted worked just fine, no issues. The second is just inconsistently reading tags, almost like it is canceling the reads halfway thru. I increased the leased rate with no difference.

Any ideas would help! Thanks!

Consider **not** using separate tag providers for each line. Just use separate folders within a single tag provider. (There can be good reasons for separate providers, but I don't see one here.)

At least, consolidate into one provider to eliminate any possible tag provider bugs contributing to your symptoms. (I suspect it is device related.)
