Posted 5 Apr 2022 I've got a client with a Modicon Unity Controller CPU 311_10 with a NOE 771_01 Ethernet card that appears to have security enabled that keeps us from looking at the code. We only tried accessing the CPU web page from a browser and it came up with a Login we couldn't get past. We didn't have Unity Pro software with us at the time but assume we will still encounter the same security login. The person who was responsible for this system is no longer alive, his company is gone, and there is no backup. Does anyone have any idea how to get into this PLC? Thanks in advance for your help.

Posted 6 Apr 2022 Hello, how will you access the controller and see the code without having the UnityPro software? Maybe the NOE7701 Web access was protected by password, but it does not prevent access to the code by using UnityPro, if the upload information was loaded to the PLC. 1 person likes this Share this post Link to post Share on other sites
Posted 6 Apr 2022 I was told the NOE Web Access uses the same credentials. We will bring Unity Pro on the next visit and see what results. Share this post Link to post Share on other sites
