1769-L33ERM Unrecognized Device

I'm attempting to install and program a new 1769-L33ERM processor and I can't get RSlinx to recognize the device and cannot go online in Studio 5000.

I assigned its IP address using BOOTP then subsequently disabled BOOTP. Flashed the firmware to 24.011 then rebooted. The processor shows up in RSlinx as unrecognized. The last L33ERM I set up works fine but I double checked the EDS. It shows it needs 0001000E006E18XX.EDS so I registered 0001000E006E1800.EDS again with no luck. I double and triple checked that my IP addresses match. I can ping the processor with no problem.

Processor indicators show OK - Solid, Link 2 - active, NS - flashing green showing no CIP connections but I don't know what that means.

Just figuring this out on my own as I go and I'm not sure what I'm doing wrong. Any help would be appreciated.

What version of Rslinx are you using ?
Are you sure that the IP address is compatible with your mask.
How is your plc connected to your PC.
Can you ping your PLC ??

RSlinx is 3.71.00 CPR 9 SR 7.1. The IPs I'm using are computer - 192.168.21.10 with mask 255.255.255.0 and the Processor is 192.168.21.4. I'm connected to Link 2 through a Stratix 2000 Unmaned Ethernet Switch using a straight through cable. I can ping the processor at 192.168.21.4 with 0% packet loss and 1ms avg round trip time. I was able to flash the firmware no problem using this setup.

I can also access the processors web server using that IP as well and it shows:

Just as a test, try using the Ethernet Devices driver instead of the Ethernet I/P driver.

The processor shows up as unrecognized with Ethernet Devices as well.

What if you right click on the unrecognized device and select "Upload EDS From Device"?

Tried that a few times. After the "change graphic Image" screen when hitting next, I get "EDS wizard encountered a critical error and must be shut down"

Did you try usb port?

You may need a newer version of RSlinx. I have ran into the same problem in the past with other old version of RSlinx on 1756 processors.

According to RA, this version of RSLinx is compatible with the controller you're using:

Try installing the EDS from the website:

Did you test RSLinx connecting point-to-point your laptop & PLC? Do you have another PC with RSLinx installed?

Ok so I have an update. The damn thing started working fine this morning. Downside is I don't know what the problem was in the first place. I shut everything down before leaving last night (I had done this several times before) and when I brought it up this morning It RSlinx was seeing everything and I could go online though it still shows as unrecognized in Studio 5000 so something fishy may still be going on. Before, I couldn't even get online with USB(the computer was seeing the processor but the VBP would not come up in RSlinx) so I'm thinking it was an issue with RSlinx. I didn't change anything from the time it wasn't working yesterday until now so unfortunately I don't know what the ultimate "fix" was. Thank you everyone for your suggestions.

Ive had this sort of thing happen with bad ethernet cables... they worked for pings and low-level comms but would fall apart when trying to do something more complex. I would replace the cable just to be safe if the problem returns.

I've had similar ethernet behavior when Windows has a pending update.

Hi,

So, I recently encountered a similar problem with L35E controller. EDS files were missing and while trying to add them I got the message : "EDS wizard encountered a problem and must be shut down."

After a bit of googling and hit and trial, i figured that problem was resolved by un-checking "Run this program in compatibility mode" option which can be accessed by right clicking and going to properties then compatibility.

I un checked the option "Run this program in compatibility mode" and checked the option "Run as administrator"

P.S: I am using win 7 (64 bit), RSLinx Classic (4.00 CPR 9 SR 10.0)
