Compactlogix losing IP-address

Dear All,

I have a brand new comapactlogix with an internal build-in ethernet connection.
I can give it an IP address. It works fine till i switch off the power. Then the IP-address is gone. And also the communication with the panel.
How can this be fixed?

Thanks.

You need to disable Boot-P after you assign it an IP address.

You will find this on the port configuration tab of the ethernet card properties. Uncheck Enable Bootp

Thanks a lot
