We have several SQLbridge modules - “distributed”, and “main” one SQLBridge and VisionModule, all works in one LAN
“Distributed” SQLBridge function:
1)is to gateway between two OPC-servres using DBtags. (trying also transaction groups w/o success). 2)here we use only one SQL DB driven Tag provider.
3)Tag configuration stores only here in DB
“Main” one function:
- Connected to “distributed” DB
- Using Real Time DB provider it wokrs with “distributed” Tags
We configured “distributed” functions, but just we starting to use “distibuted” tags on “main” server all tags goes to “Stale” state and it looks like it stoped to execute on “distributed” machines cause OPC-gateway dont work.
We try to import tags from csv format, but the Designer appears to start creating some of the tags, but then after a few seconds progress will stop with “Waiting for Gateway”. The request will eventually timeout after 60 seconds.
Once the timeout occurs the database tag provider on the gateway appears to be hung. If the tag referesh icon is selected, the Tag Provider only displays the “Waiting” icon until the gateway once again times out after 60 seconds.
This problem is similar to viewtopic.php?f=72&t=7302&p=22078&hilit=Driving+Provider#p22078 but it occurs in 7.3.2
