Thank´s for the idea but ......
The problem is that i do the detection on the pg interface and doesn't connect to the address that appear .The cpu 214 is working OK.

Do you use Siemens PPI adapter or some Chinese equipment?
Is your COM port integrated with motherboard or you have additional card?
Check COM settings in BIOS/Windows, check PPI adapter speed selector.
If possible test with another CPU.
Read S7-200 System Manual

I use a Siemens PPI adapter,6ES7 972-0CB20-0XA0.V1.3

I already do the test on another equipment and it worked OK (cpu224).
Thank´s for the help .....

It looks you have USB adapter.
Install SIMATIC PC Adapter USB Software V2.0

You should also update your firmware

First, make sure your adapter is properly installed in system.
In Windows 'Device Manager' under 'Simatic Devices' there should be listed 'SIMATIC PC USB adapter'.
Next, check that 'PC Adapter(PPI)' interface is installed in Micro/WIN.
If you still can't communicate, my idea is that you should check baudrate (PC Adapter(PPI)->Properties->Transmission rate). Default value is 9,6 kbps, maybe your PLC is set to 19,2 or 187,5 kbps.
If you don't know your CPU address click 'Communication' icon and then 'Double click to Refresh' (because it is scanning process make sure that 'Highest station number' is set to 126).
Last chance, you can use WIPEOUT tool to reset PLC to factory default (your program will be also erased!).

s7200 ports can be programmed for different kinds of communication

just pot your cpu in stop with th switch , cpu will go in default PPI communication
leave cpu in stop
now try with all baudrates

when you put cpu back in run , cpu will go back in the communication mode it was before , because port configuration happens in startup
