Block Transaction Group with OPC Data

If I am using a Block Transaction group to much a large chunk of OPC data - at what rate is the OPC data polled?

I know if I use SQLTags and they are leased they are polled at the fast rate once part of the transaction group.

Since you don’t really specify a scan class for the OPC items I’m not quite sure how fast they will scan - does anyone know this?

I am trying to keep it fairly slow since it just for recipes and over radio comms.


The OPC items in a Transaction Group always run at whatever the Execution Scheduling rate is. The only time this isn’t true is if you use the ‘Override OPC subscription rate’ in the Options tab.
