Hello, I am having an issue with block transaction groups. I select “Table Action” option “insert changed rows” and the transaction group writes duplicate rows to the DB. The rows are not changing. I can do the same thing with scripting if there is some inherent flaw with the block transaction, but I would like to understand why it is not working. It is simply a slow scheduled transaction and I can perhaps use a trigger as well which may clean this up, but right now for testing, there is no trigger. I am trying to write the history of a fifo array from a parts/inspection tracking data file (an array of UDTs that are themselves string/int/real arrays) created in the PLC.
