Posted 10 Dec 2016 Hi! I have this CQM1 CPU21 plc running but the problem is that I'm not able to communicate using CX Programmer V9.5. Under the "Backup PLC" section, the drop down list for the specified PLC is not included. Is there any update/software to be use in order to communicate the PLC? I have "USB to RS232 Cable" that I have been using for different PLC, I also have this OMRON CQM1-CIF02 Interface Unit that is not also working upon communicating the PLC. I'm thinking that the software itself has a problem or needs an update. I hope someone can help. Newbie here in OMRON PLC. Thanks!!! Marky Share this post Link to post Share on other sites
Posted 10 Dec 2016 I think that the PLC Backup Tool is not something available for CQM1. Anyway that is not the way to connect to PLC's. Instead, go to -->PLC --> Work Online (Or Ctrl+W). 1 person likes this Share this post Link to post Share on other sites
Posted 11 Dec 2016 Hi @pfort! Thanks for the reply! Is it OK to Work Online even though we don't have a back up program? Share this post Link to post Share on other sites
Posted 11 Dec 2016 Once Online you can upload the program, but with the CQM1 you will not have the comments. Share this post Link to post Share on other sites
