When I open my application right after the launch of iFix I get a umber of pop-ups:
"Workspace Application
Error Number: -2147187524
Field's value not known
OK"
I just press OK - and after 8 of those messages it works. If I keep iFix running and stop and start the WorkSpace - I dont get these pop-ups any more.
I have tried to locate them - but it is difficult. My code is repeating - so eventually when data is available, there is no error.
What exactly does this error mean?
And can I suppress this particular message?
Background: It is all related to slow driver performance - caused by RockWell FirmWare V21. I have done tests - and together with KepWare support found out that it seems that "Logical Blocking" as Protocol Mode helps a lot - but still it is not as good as before (FirmWare20 or Siemens S7A for that matter) - where none of there errors occurred.
