Siemens Text Display (TD 200)

Dear All,

I have system which include S7-200 and TD 200
I am facing problem when TD200 alone connected with S7-200 CPU 224 then continuously having "CPU NOT RESPONDING" message on TD 200 Screen. i just faced this error while replacing the old display to new one, but it still working with my old display. I checked the cable its fine.
Some one told me to check the baud rate,starting address of data block& parameter block are matching..but i don't have any idea, how to check that

I'm a beginner. Kindly help me to solve this problem.
Regards,,,

Anu

3.8 Using the TD 200 Setup Menu Option - Section of this manual will help you set up the TD200. This should be set identically to the old display.
