s7-1200 LED ERROR CPU

Hi,

I have a problem with the CPU, once time I compile all (HW & SW all blocks) I'm unable to connect.

When I scan, detect an element (CPU) but then any connection possible.

See the pic attached.

Help please.

The Ip congigured is 172.26.0.99.

And when I connect to CPU found 192.168.0.1

Hello,

then you should set the configured IP on the PLC before you download.

In the projecttree you have a point "Online Acess"

expand and go to your used network adapter

start here "found accessible node"

select then the plc and open Online&Diagnostics

here under functions you can set the ip-adress

set the configured IP and then try to download the project
