Yes. Post your configuration so we can see what it is. - Can you ping the PLC? - Can you browse the PLC's web server. (I think it has one.) - What is the network route between your Ignition gateway and the PLC? Setup should be a matter of going to gateway's Config | OPC UA | Device Connections | Add new | select Allen-Bradley MicroLogix and enter the IP address. Welcome to the forum. ---

yes i can ping the PLC, but no i cant access the web server, and here is the config, i have other devices that connected without any issue, so im a little puzzled as of why this one is giving me the headaches ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/c/2/c2740cb2a61a5547d91298e9055680df0be034e8.png) and thank you for the welcome ---

Connection Path should probably be either `1,0` or blank. ---

> [@Kevin.Herron](#): > > `1,0` I tried that, but still no success, i also tried accesing the port with telnet ip 44818 but no response whatsoever but the thing is that we are migrating a program form indusoft to ignition, and on indusoft they managed to get info from the plc hence they have connection ---

If the 1100 has old firmware, it may need to connect via port 2222.
