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 contineously having "CPU NOT RESPONDING" message on TD 200 Screen.

Kindly help me to solve this problem.
Regards,,,

have you downloaded the data block to the plc for the td200 to read from?

Hi,

"CPU not responding" means your TD 200 is unable to locate the CPU....Check the cable, baud rate, starting address of your Data block & parameter block address...They should be the same as configured...
