Hello, I am seeking assistance with my Cognex DM 280 barcode reader connected via ethernet to CompactLogix 5380. I have successfully added the device and can see numbers when it scans, but I am unsure how to determine which code corresponds to which color. I have been searching for Cognex DM280 add-on instructions for Allen-Bradley with no luck. Has anyone encountered this issue before and can recommend the best approach for solving it? Thank you, Paul.
I opted for the DM260 AOI/EDS as a solution, which proved effective. Cognex recommended this workaround, but there is uncertainty whether they will develop a similar option for the 280 model in the future.
I assume you manually added it following their online instructions. Have you been able to successfully follow their comprehensive guides on the configurations of the assemblies? You can refer to this in-depth guide for more information: https://support.cognex.com/docs/dmst_2322/EN/Industrial_Protocols_Manual.pdf. The last setup I worked on was for a 300, so I would expect the 280 to require a similar setup since the 200 modules are also an available option.
Pilionis inquired about integrating a Cognex DM 280 barcode reader with a CompactLogix 5380 PLC via Ethernet. While the device successfully scans and displays numbers, determining what each code represents, such as color, poses a challenge. Pilionis sought Cognex DM280 add-on instructions for Allen-Bradley systems but could not locate any resources. Seeking advice from others who have encountered this issue, Pilionis asked for the best approach. Additionally, Pilionis expressed difficulty in obtaining the EDS for DM280.
Hi Paul, you're in luck, I've worked with the Cognex DM280 and CompactLogix 5380 before. From my understanding, the barcode doesn't directly tell you the color, rather, it reads the information embedded in the barcode which could lead you to the color or any other relevant information. You might need to link your barcode data to some sort of database or lookup table that associates each code with its respective color. Regarding the Add-On Instructions (AOI), I had a tough time finding it too, I suggest directly contacting Rockwell Automation or Cognex support for assistance. They were helpful in my case. Good luck!
Hi Paul, it sounds like you're on the right track with the Cognex DM 280. In regards to distinguishing colors of the barcodes, it isn't something the scanner can detect directly as it's built for reading, not color differentiation. However, you can indirectly achieve this by having different barcodes for different colors and configuring the CompactLogix 5380 to appropriately interpret the data from the scanner. As for add-on instructions, consider contacting Cognex Support or check the Allen-Bradley's Knowledge Base - it's usually a treasure trove of information. Hope this helps you out!
Hi Paul, hopefully, I can provide a bit of guidance. My best tip would be to check out the Cognex Insight Software, if you haven't already. It should help you correlate the output string with the scanned barcodes, eventually leading you to decipher which one corresponds to which color. As for the add-on instructions, I'm not sure about DM280m, but Cognex DM260 had a document on the Rockwell sample code library. With some modifications, it might be helpful to you. Don't forget, Cognex support is pretty good, so contacting them directly could be another efficient way to navigate your issue.
