I connected a 1769-L38ERM to my PC via USB cable. I have 2 known problems:
I tried to troubleshoot on my own but to no avail. What I have done:
After all these steps, it still does not work.
Strangely enough, I am able to communicate with the PLC with Studio 5000. For example: download/upload ladders and read/write/config with Studio 5000. Studio 5000's "discover modules" does not work which I think is related to this issue.
This PC RSLinx is revision 4.00.01 CPR 9 SR 10.0

- PLC is listed as Unrecognized Device with a yellow question mark. [3]
- Unable to view modules connected to PLC in RSLinx. [3]
I tried to troubleshoot on my own but to no avail. What I have done:
- I have enabled "Enable EDS File Automatic Upload". RSLinx shows a blue progress bar for about 10 seconds or so beside the PLC icon; Registering EDS etc etc [1]
- I have tried to Right click "Upload EDS file from device". Rockwell Automation's EDS Wizard window pops up. I completed the steps with no errors at the final page of the Wizard. [2]
- I tried to install the EDS manually by copying and pasting the EDS files and ico files from C:\Users\ USERNAME \AppData\Local\Temp\RSI_EMBEDDED_EDS to C:\Users\Public\Documents\Rockwell\EDS and C:\Users\Public\Documents\Rockwell\EDS\Icons. [4]
- In RSLinx -> Configure Drivers -> deleted AB_VBP-1 (Virtual backplane) and added it back again.
- Restarted my PC.
After all these steps, it still does not work.
