High all,
We have upgraded to the SLC 505's in order to better instruct our students. I set up a standard 192.168.0.x scheme and have used Rockwell's Bootp server to assign addresses. I disable DHCP/Bootp afterwards. This seems to work for a while but after a few power cycles, the modules lose their address.
I read some of Rockwell's manuals suggesting the setting up of the Channel 1 configurations. I have done this also. The method I used was to set up a connection using the serial cable, then configured the channel (MAC address, IP address, and disable Bootp), then downloaded to make sure new channel config was written. When I come back after the weekend some of the modules still lose their IP address.
The problem is that in our lab these machines may be turned off for weeks at a time as we teach other classes in it. When they power back on, we cannot PING the address. Perhaps I have missed a step or done it all wrong.
Of course we can always run lab over the serial cable but showing the versatility of Ethernet would be wonderful to incorporate into our lab.
THANKS for your help and sorry if I posted incorrectly, this is my first time!
