Posted 30 Apr 2019 Hello all, hoping for some help with an issue we currently have. We have a stationary unit provided by an automation company which is controlled by an Omron CP1E PLC unit. We have just purchased and installed the latest CX-One software with key etc as we are aiming to make modifications to the machine. When connected to the PLC via USB the drivers install however we get an error message when viewing the driver properties stating windows is unable to verify the digital signatures. When attempting to connect via USB direct online we get a failed to connect to PLC error. We have tried updating the drivers but it states the most up to date drivers are installed. Also tried uninstalling and reinstalling drivers. Anyone able to offer any advice? We have no experience with Omron so unsure if there is something we are missing. Thanks!

Posted 30 Apr 2019 Thanks gtsuport. I actually followed the instructions in that video but I still have the digital signatures error in the driver info. The PLC is also displaying correctly in the 'USB devices' drop down rather than 'other devices' but it is still failing to connect to the PLC. Share this post Link to post Share on other sites
Posted 30 Apr 2019 Couple of things, latest USB driver is attached. Also make sure you update your software with the Auto Update Tool. Should be in your Start Menu, Omron program group, CX-One option. gtsuport PLC_NS (Windows 8, 10).zip Share this post Link to post Share on other sites
