Posted 15 Nov 2013 I have a Quantum PLC and a 140 NOE 771 00 which has been sitting on my shelf for several years. I need to use it but do not know the IP address of the NOE module. I tried the bootP utility and got no response. How do I determine the address or reset it to factory default? Share this post Link to post Share on other sites
Posted 18 Nov 2013 You could try to hook it up to a network and look at the traffic with Wireshark... Geir Share this post Link to post Share on other sites
Posted 18 Nov 2013 It usually gets a configuration from the CPU, at least the new ones do. This is old, but I would expect it to get it's IP the same way. When you plugged it in to a backplane, is an NOE configured in that location through the programming software? You might want to try DHCP, but as others have said Wireshark will help determine what the device is doing. Share this post Link to post Share on other sites
