Draker,

as far as I know the S7-200 family has no dispaly of it's own. So when you say

before the display showme "The CPU can't answere"

I assume you're talking about an external display. For this reason I think it's not the PLC who's faulty, but the display or the communication channel between PLC and display.

Please clarify.

Kind regards,
