What is a reasonable ?

[jwdz]

If  Error status is "F" ,running it  and  x-y=2000mS

and Error  status is "T" ,running it also  x-y=2000mS

Why?

If you open the VI (right click and select "Open Front Panel" and then "Convert") you will see that it simply passes the error through and doesn't do anything about it. You can modify it to work as you want.

Coz its just  a delay function and does not depend on error state

I add a "SubVI with error Handing" of Template. 

It is good.
