Posted 19 Feb 2020 I have an NJ-PLC tied to several components via EtherCAT...one of those components is the NX-Safety CPU. Customer had us design the system so that the NJ-PLC stays powered even if the Main Disconnect is pulled. The problem I am running into is that the NJ-PLC will log several EtherCAT Loss "Minor Errors" when the Main Power is disconnected from the slave components....that in turn will not allow my NX-Safety CPU to run after everything is all powered back up again. The only way I can get the NX-Safety CPU to function again is to manually clear the "minor errors" while online with Sysmac Studio. Is there some setting somewhere I can turn off to NOT monitor EtherCAT Communications loss or some other way around this issue?? Again, I am very novice at Omron programming, 28 year AB programmer.... Thanks Share this post Link to post Share on other sites
Posted 19 Feb 2020 https://assets.omron.eu/downloads/manual/en/v2/w505_nx_nj-series_cpu_unit_built-in_ethercat_port_users_manual_en.pdf There is an instruction to reset the error. ( ResetECError) Please refer to page 6-27 of the above manual. I hope this will help you out. Regards, Garry Share this post Link to post Share on other sites
Posted 19 Feb 2020 Thank you, yes that will help.... With that bit of knowledge, I was able to find that "reset logic" in a previous program done for this company written by a former engineer, no longer employed here.. Thanks again for the help.. 1 person likes this Share this post Link to post Share on other sites
