However if the tags that use the Direct (Default) scan class are removed, then the Leased tags return to running fast.
I am running Ignition 7.5.6 (b1317) and all the modules for that version.
I apologize if this was covered here, but I have searched the forum and couldn’t find anything, but if I missed it, please point me in the right direction.
The only thing I could find that sounds similar was a reference in the change log:
[quote]Ignition Platform - 126.96.36.1995
OPC-UA - 188.8.131.523
Fixed - Fixed a bug where a driver node would always use the lowest sampling rate it had ever
seen when determining if its value was currently stale rather than the lowest rate of
current monitored items. This only occurred if there were more than one monitored items
for the given node.This was especially likely to manifest itself when one tag from a
leased scan class and one tag from a direct scan class were subscribed to the same node.[/quote]
I tried down-grading to 7.5.5, 7.5.4 and variations of OPC-UA module and AB driver (using PLC5, btw) but nothing changed, still same need to delete Direct tags before fast Leased rate. Also, I’m using latest java version 7.21
Please let me know if there is a work around to allow both scan classes to run together for the same device.
