Using Strings in Transaction Group

Ignition
1

In Ignition 7.9,

I have a historical transaction group with opc tags from a control logix plc. Three of those tags are strings, the other 10 or so are Int4.

When I drag the opc items over to the group item window, the string items have two components; the length and the string value. When I drag over just the string values for those three items, I then get three items all called “STRING” which I then of course map to different columns in the table.

BUT, Ignition gives me a warning in the Events box that says “WARN The following names are defined multiple times in the group: [STRING]. Item references may not work correctly…”

Is there a different approach I should be taking with these strings, or is this a warning that I can just ignore in this case? The group seems to run fine…

Thanks.

Just rename the items. There’s no requirement that the item name or the table column name have to match the underlying OPC item. That just what you get from dragging.

Ugh! I had no idea I could change that field!

Thank you Phil!!
