Turn on dip switch 5 on the CPU. This will make the 9 pin port use the default RS232 communication.Default is Host link, 9600, 7, E, 2. Make sure to set CX-Programmer with these same settings to communicate with the PLC. Share this post Link to post Share on other sites
Posted 5 Feb 2020 Michael Walsh I did it but when the cx programer do the automatic online search at the end show ¨failed to connect to plc¨ Share this post Link to post Share on other sites
Posted 5 Feb 2020 Just start a new project set the PLC as a CJ1M-CPU11, choose Sysmac Way as the communication type and 9600, 7, E, 2 as the settings. Choose the correct communication port number as well. See if that works. Share this post Link to post Share on other sites
Posted 5 Feb 2020 I will assume that your PC clock is valid, not sure how it would be invalid. I would register your software and update it to the current version (9.73). If you still have this issue, you may need to uninstall and reinstall CX-One. I have not seen that error before. Share this post Link to post Share on other sites

Posted 11 Feb 2020 Try to "Clear All Memory Areas" under the PLC pulldown. It sounds like your PLC may have completely lost its memory and it may be in an odd state. After clearing all memory areas, try to download your program. Share this post Link to post Share on other sites
