Posted 24 May 2020 thank you for your reply, i set all DIP switches according to the attached file.at first both CPUs have fault LED but after download and DIP switch setting now one CPU is off always. can help me for setting this item? thanks Share this post Link to post Share on other sites
Posted 26 May 2020 Did you download to each CPU? If CX-P said simplex mode, it didn't transfer to both CPUs on its own. Share this post Link to post Share on other sites
Posted 27 May 2020 No i dowloaded to one cpu. Other cpu must be downloaded separately? I use ethernet module when download ony one cpu dowloaded.how can i doenload to other cpu?with serial port?

Posted 27 May 2020 I'm not certain on that, it's been a couple decades since I touched one of these. Share this post Link to post Share on other sites
Posted 27 May 2020 I do not know if you can write to both CPUs using a serial cable. I normally use the peripheral port and it works OK. Share this post Link to post Share on other sites

It means you download to one cpu and then download to another one using peripheral port? Then two cpu must be downloaded separately? I could not download to both cpu, it says that cpu is simplex mode. Can anyone help me? Share this post Link to post Share on other sites
Posted 28 May 2020 I recently completed a job with a CS1D using the 67HA processors and the peripheral port for programming and the program was transferred to both CPUs every time. It appears you have the switch set to duplex - have you tried pushing the INIT button at all? I cannot remember what it does. Share this post Link to post Share on other sites

Thank you bob, yes my problem begin when i press INIT button, first i download to both cpu using serial port and everything been ok only cpu was fault. After that i press INIT button and one cpu goes to off and i can not download to it. Even when change the dip swith to left cpu in duplex, the cpu not work and i can not download to it.
