Posted 10 Jul 2018 Hi This is a continuation of the following post: http://forums.mrplc.com/index.php?/topic/35096-error-changing-unit-on-ethercat-coupler/ But since it is a different error I thought to write it on a new post. The problem I have is, once I reseted my controller, cleared all memories, whenever I want to transfer my new program to the controller I get this error: I clicked on the "Update Configuration and Setup Transfer Data" command but nothing happens and the problem still persists What does "perform a rebuild operation" mean? What can I do, the ETHERCAT configuration is correct since the last post error was fixed. Any idea? Share this post Link to post Share on other sites
Posted 10 Jul 2018 From the main menu choose "Project" and then "Rebuild Controller" Solve all errors before you try to download. Share this post Link to post Share on other sites
Posted 11 Jul 2018 Thank you. Well,l I solved all the problems now, one by one, with great effort I could finally understand how more or less sysmac works on this matters. Share this post Link to post Share on other sites
