Hey guys, looking for some assistance understanding the perks of using SQL Bridge instead of or as well as Tag Historian. I don’t quite see what its major selling points are. I’ve used both together and separately but in my mind if I’m just chasing data logging, the tag historian is the best option.
For instance, I’ve played around with writing an application that writes a huge amount of data to an L84ES GuardLogix PLC, about 60,000 DINTS. I can’t write to an array as a whole or individual tags because it is far too cumbersome and a huge resource hog to have Ignition cache that information at which ever scan time. Instead I wrote some code that uses the system.opc functions and I write to the tags directly without defining them in the tag browser.
• Could SQL Bridge help me do this?; or;
• Is using system.opc commands perhaps the most efficient way?
I’ve also sent this on to our friendly neighborhood Ignition support but thought I’d run it by you guys as well.
