Hi, I'm developing software for AB Compactlogix/Panelview application. System Comm. is ethernet. I configured ethernet network yesterday assigning new IP address to laptop computer with similar addresses for the devices on the logix network. But back at the office today, of course, same ethernet port now fails to connect to office network router/internet service. Unknown to me, the laptop was reset back to previous settings, thus resetting the IP address. and now it works on the network and internet service. But I'll have to reconfigure the IP address to reconnect to Logix network. Any suggestions as the best way to keep switching IP addresses?
