Hi

I recently encountered an issue when I was trying to write a block of values from a table to the PLC using the block group. I am wondering if it possible to order the data for the group before it is written. I found that unless the PLC array values [0],[1],[2] etc are ordered ascending in the DB table they will not get written correctly. I fixed the issue by creating the table with everything ordered ascending but would like to know if it possible to ensure it is correct by ordering before writing

Thanks

Aidan

Yes, there is a third tab at the top of that groups that allows you to see what the block looks like.
