we have a project with DV 9.3.1 and I want to add one MD controller that it's firmware revision is 7.2 .
It commissioned normally but we can not download it because of revision discrepancy.
So I want to upgrade that controller firmware from 7.2 to 9.3 but when I run "DeltaV controller ,I/O upgrading utility" , that controller not recognized and not appear in related window for selection.
what can i do for this issue?
