Remco Posted June 22, 2011 Report Share Posted June 22, 2011 Hello, Why not use ethernet? I give support to Unitronics OPLC's and Cognex Vision Systems at Isotron in the Netherlands, and made already communication with it together. I always used the ethernet, and not the serial. But you can go with Modbus, or native mode, depending on the task you will do. Attached 2 examples, one for Modbus and one for native mode. If you need more, let me know.

DonM Posted June 23, 2011 Report Share Posted June 23, 2011 As a starting point, you could take a look at the FB Protocol example projects. Choose 'Examples...' from the Help menu in Visilogic and then drill down to the directory 'Version 900\Project examples\Communications\FB Protocol'. Don.

How do you know at which port to communicate with it? Regards Link to comment Share on other sites More sharing options...
AlexUT Posted January 15, 2020 Report Share Posted January 15, 2020 Hmmm. This topic is from year 2011. Most of peoples not active for years. Camera models beeng changed too. Hope it is better to read Cognex manual. Isn't it? B.R. Link to comment Share on other sites More sharing options...
Remco Posted January 27, 2020 Report Share Posted January 27, 2020 Hello Tallo, a bit late, but the modbus communication in the example was done with an older Cognex Insight camera, using Modbus TCP as a slave. standard is port 502 used for it in the camera and the PLC. which Cognex camera are you going to use, and what data do you want to transfer? if it is an UniStream I would recommend using the Ethernet/IP option, I also used that one, next to the Native mode.
