I have had the same experience with CP6x and AC500. Unfortunately I didn't find solution.
Hopefully there are no unexpected stops of the CPU.

In our project we have used two plc. And this two plc communicates with hmi when two plc are in on state. But when one of the plc go to off state an communication error occurred and because of communication error hmi send delayed response .

Yes, that is true. It happen with me the same.
As I explained, I didn't found solution, just keep both PLC's always run :-)
In my opinion that is functionality of the panel's software which couldn't change
