Comm.Failure and related animation

Dear All,
When the communication failure is happen, I am getting the small red rectangle at right side corner of the Numerical value display. At the same time, Is it possible to make any one of the internal Boolean variable to "True"...?
Best Regards,
A.Navaneet.
