I’ve set my block transaction group to trigger after value change and I’ve chose update mode to be DB to OPC. When I write a value to DB by PLSQL, I see in Database Query Browser that the value changed, but the tag in Designer remains still. After changing value of one of the other tags, the value I’ve sent via PLSQL is written to the tag.
This doesn’t happens when I use timer execution, but I want the values to be updated on-change.
Thanks for your help.
