Hi, i'm trying to read data from an AB PLC (see details on pictures) but without success. ![AB_CLX](https://us1.discourse-cdn.com/inductiveautomation/original/3X/f/5/f53ba3d7ffa7e48d00e16860799f1cd815281575.png) Using the "Control Logix Legacy Driver" i cannot connect (Faulted Mode message) Using the "Allen-Bradley Logix Driver" the driver is connected but i cannot "browse" data (ok, it's an old firmware). ![AB_Diagnostics](https://us1.discourse-cdn.com/inductiveautomation/original/3X/b/b/bb65aea7f952157d87fa333e56ae29dad72e5b5a.png) How i can define Tag's Paths manually? I can read data correctly using my custom driver (an old c# IEP driver implementation). I'm not an AB expert so i think that i'm missing somethings.. ---

What are the firmware revisions of the PLCs you are trying to communicate with? What is the physical comm path between the PLC and the Gateway? ---

Version 20.12 should work with the Legacy drivers, but that model needs the **CompactLogix** driver, not the **ControlLogix** driver. ---

Hi, thank for replies. I added a CompactLogix Driver but the message is always the same. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/7/7/77f597ec6115949607c2101c6ac8ca80ff8bd3fe.png) I would like to read some "GLOBAL" tags: 1 Integer and 3 strings. ---

Are there any errors in the wrapper logs? Not sure what’s going on. Both drivers should work with this PLC and firmware version. Device must be in a weird state or not able to allocate more CIP connections or something. You won’t be able to read tags unless the browse can be completed. ---

I'm now curious what [my alternate driver](https://forum.inductiveautomation.com/t/automation-professionals-ethernet-ip-communication-suite-v2/68190) would get. ---

> LOGIXDriver \> Browse failed: status=0x05 [path destination unknown] , additional=[0x0000] BACKPLANE = 0x01 CPU SLOT = 0x00 But i think that it's a firewall problem.. i'm going to call the IT. I'll inform as soon as possible. ---

For your info: i asked to switch-on another similar machine and the Browe is working! I read that in some case it's necessary to re-download the SW on CPU to make it working.. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/b/0/b0520cb3e467f5ad451f431ab36d19a5dc396774.png) ---

sharan, please start a new thread. This thread is related to **connection to the PLC**. You seem to have already achieved this. You can delete your previous post and I'll delete this one.
