Cant Set up default IP address in simpl windows!

[Tones]

Hi,

I guess im doing something silly, but im trying to connect an old TPS 6L to a CP2e via ethernet but they just wont talk to each other!

I am trying to set the default IP address in configuration manager for the TPS 6L but it just dont give me the option to edit it from its current setting of 127.0.0.0.

Toolbox finds the TPS 6L every time on discovery tool but when I try to connect it says "Cant connect"

What am doing wrong?

Thanks
