Yes, you should be able to use the "Try ... Catch" block to capture any exceptions during the execution of the ACE calculation. You can refer to one of the previous post here about this. Notice that even when we capture the exception, you should be using
OutputTag.SendDataToPI = FALSE
statement to tell PI ACE not to write "Calc Failed" event to the output tag at the end of execution.
Based on the post you have indicated, I noticed that I was using "Catch ex as SystemException" instead of "Catch ex as Exception". Now the Try...Catch commands are working fine in ACE.
Thanks for the info.
