Can't upload from PLC S7-200 smart

Dear all

i had tried upload from plc s7200 smart throught ethernet, setting Ip address in "Obtain an IP address automatically".

In step 7 micro/ win smart, i had already find PLC but when i press "OK" error appear "No connection to the specified address could be established. Possibly an invalaid or non-existent address."

i had tried change IP address in PC to : 192.168.0.1 but this situation not change

please help me!

Try setting the CPU in STOP. If that doesn't solve the issue, make sure the network adapter you are using to connect to the S7-200 is in the same subnet as the PLC itself.

For example if your network adapter is trying to use 192.168.1.1 and the PLC is at 192.168.0.132 or whatever, the two devices won't be able to communicate because they are not in the same sub-net.

Hopes this helps.

thanks for your help.

1st case: i dont know how to change plc to Stop because i cant see any switch on PLC

2nd: i tried change IP adress on PC: 192.168.0.1(IP adress on PLC is 192.168.0.103), but this situation no change. I can't upload program from PLC despite i can find PLC
