Isakovic Posted September 7, 2020 Report Share Posted September 7, 2020 Hello, I need to add two columns to an existing Data Table, in VisiLogic this can be done without losing values, I'm not sure how it works in UniLogic, I remember once editing it and all values went to 0. Can I add a member to Data Table struct and retaining values in old columns? I would back up old table, but problem is that I can't read the values in online mode and back them up, I get this error: Connection to plc was over Ethernet, ladder works normally in online mode so I wouldn't say it's a connection issue. If new columns cannot be added without losing values, my second question would be: Is it possible to read values via UniApps and save DT to USB stick?
