Hi, My customer using ignition and they will like to connect my plc. I check some video and I see only need to add ignition configuration opc from ignition and my plc only provide ip address then hit connect can direct browse my plc tag ? So my plc CompactLogix 5380 , don’t need programming or coding ? Just regular tag from plc , ignition can direct read or control the tag ? I see opc just built in on ignition software Thanks ---

The docs should help you on this, [https://docs.inductiveautomation.com/display/DOC81/Connecting+to+ControlLogix](https://docs.inductiveautomation.com/display/DOC81/Connecting+to+ControlLogix) Welcome to the forum! ---

Download Ignition, install and try it out. You just have to reset the trial every two hours. ---

Yes, Ignition's OPC server will allow you to browse the tags in your PLC. > [@Eng\_Li\_Kiek](#): > > So my plc CompactLogix 5380 , don’t need programming or coding ? I'm not sure what question you're asking here. The PLC will need programming in order to perform it's intended function. There is no additional configuration, aside from general communications, needed for Igntion to connect to the PLC. > [@Eng\_Li\_Kiek](#): > > Just regular tag from plc , ignition can direct read or control the tag ? Ignition comes with a OPC-UA server. The AB Device Driver, allows for OPC subscriptions to be made to the PLC. However, there are some caveats to the best way to configure Ignition to work with AB devices. Also, avoid adding tags to ignition that you don't need in Ignition. **Don't** just drag the entire `Controller` folder into ignition. Here are some good topics that are of relevance. > [@Ignition & Logix Best Practice Tips for better communications](https://forum.inductiveautomation.com/t/ignition-logix-best-practice-tips-for-better-communications/60386): > > Hi All, After a whole bunch of issues I have gone down the rabbit hole of what is wrong with our setup on site.

I went back to basics and dragged and dropped the tags from the OPC browser into the Tags Folder, but the quality is bad and there is a red x next to them. What is more confusing is that some are working and some are not. I cannot see any similarities between the few that aren’t working. Data type, In and Out types are working and not working. I can create a new UDT as an In/Out but this seems cumbersome. In this case, I would need to create tags only fo…
