1756-EN2TR Ethernet Module - Change Subnet Mask

[dalporto]

Hi. Rockwell learning curve 132-1b.




I was having trouble to change IP address on a EN2TR.


Finally found out that I need to change the IP offline, then online.


Still wasn't working until I figured that my mask was wrong.


I changed it online too and it's working now, but I feel that it should be set elsewhere that only online, right?


I cannot find it.


Thanks.

Hello. I cannot understand the problem very well. Are you using RSLinx?

IIRC, the IP is device level. You set the IP at the device.
