Dear gentlemen, our current setup involves a Beckhoff PLC with EthercatMaster connected to an EK1100 with an EL6652 EthernetIP Master. The goal is to establish communication with a Cognex Insight 7000 series camera. Despite my efforts to configure everything correctly, I am experiencing issues with establishing active communication. The diagnostic page of the EL6652 indicates errors such as 0x8003 (Configuration error) and 0x8004 (Unsuccessful FwdOpen-Response received). Unfortunately, Beckhoff does not provide clear instructions on resolving these issues. Can anyone provide guidance on troubleshooting steps or areas to investigate? This configuration is brand new and has not been operational before. Any assistance would be greatly appreciated. Thank you.

Thank you, L33er, for solving the issue. I had to set up a test environment on my desk in order to capture screenshots. During this process, I had to reconfigure the IO settings and discovered a 7000 series EDS file that was previously used. However, I also found a 7900 - 7500 EDS file which enabled successful communication. Your question was instrumental in resolving this, so thank you! - Jack
Hello there, it sounds like you're dealing with quite an intricate issue. Have you checked the subnet masks and IP addresses? Sometimes, an incorrect subnet or IP address could be causing the configuration error. Additionally, check if the routing tables in your EtherNetIP devices are configured correctly, since not doing so can result in the FwdOpen-Response error. Furthermore, in many similar circumstances, it's often the case that the scan rate is too fast for the devices to handle, so you may also want to consider slowing that down. Lastly, I'd recommend contacting Cognex directly for support, as their technical team would be experienced in tackling such issues and will be able to provide step-by-step solutions. Hope you find a solution soon!
It seems like you're dealing with a complex issue but don't worry, we'll try to figure it out step by step. First off, I would suggest going back and double-checking the Ethernet/IP configuration in TwinCAT system. Make sure you've set the correct instance and attribute numbers for Assembly objects. Sometimes, an incorrect parameter in the configuration can lead to these kinds of error messages. If that doesn't resolve your issue, it might be a compatibility problem between Beckhoff and Cognex devices. You might want to check the Cognex Insight 7000 Camera's Conformance Test Data for information about which PLCs it has been verified to work with. Lastly, try resetting both devices to their factory settings and go through the setup process again. It may take time but it could be worth a shot. Good luck and let us know how you get on with it!
