Posted 19 Oct 2018 (edited) I have a cpu33 that I had issues with a bad battery and it loaded from memory card. The version on the card was old so I decided to download the latest version from 2 days ago to it. When I did, I lost communication through ethernet. Can't connect through usb either. The thing that baffles me is that I can ping the plc at the address and I get a reply. Any help/suggestions would be greatly appreciated as I am not familiar with omron plc's at all. Also on the display it cycles through Er HE 1P 07. Edited 19 Oct 2018 by Cabby Share this post Link to post Share on other sites
Posted 19 Oct 2018 The error HE is tag datalink communication timeout, and IP 07 (not 1P) is the last octet of the erroneous node IP address. Did you download only the program, or data memory as well? The latter might change the communication settings, as well as "Set defaults" in the Ethernet port configuration.

Posted 20 Oct 2018 I downloaded all. Guess that's where I really screwed up. HE being tag data link timeout is active I'm guessing because it cant see the touchscreen. The ip is 192.168.10.7 so the ip 07 makes sense. I was hoping to get on with the usb to check settings for port config but that was also unsuccessful.

Posted 20 Oct 2018 (edited) See this thread. Probably, it will help you at least with the USB communication. http://forums.mrplc.com/index.php?/topic/34230-cp1h-xa-failed-to-connect-to-the-plc-with-usb/#comment-160191 Edited 20 Oct 2018 by Sergei Troizky Share this post Link to post Share on other sites
Posted 20 Oct 2018 Okay. Thanks for the tips, they got me connected. Now when I try to transfer to the plc all goes well until I get to the Special Unit Setup. Then I get failure window and it tells me download failed. Any suggestions on this one? Share this post Link to post Share on other sites
Posted 20 Oct 2018 Also along with my other problems I've also got a fatal error. IO setting error 0X80E0. Does this mean that I have to tell it what's in each slot because it didn't transfer when I downloaded? Share this post Link to post Share on other sites
Posted 20 Oct 2018 Double-click the "IO table and unit setup" in the project tree and transfer the IO table from the PLC. There is such icon there. Share this post Link to post Share on other sites
Posted 20 Oct 2018 Tried the transfer from plc and it failed, so I entered each slot manually and transferred them to plc. This resolved all issues and no more errors. Now I can get back to the original problem where I started yesterday. Thank you very much for your suggestions and help with this issue. I tried omron support and was not impressed with response time (was on hold for 2hrs finally left message and still no response). Don't know if this is normal but was my experience yesterday.
