Posted 15 Jan 2022 Hello, I installed CX-One version 4.5 on an older computer and production equipment. I get an error when I open CX-Programmer (version 9.7) for the PLC IO Table. The only option is 'OK' and everything seems to work once I have the program uploaded. Periodically it will complain with the same error for the PLC IO Table. I also get a pop-up saying I need to install the CPS file for the PLC that I am using (CJ2H-CPU66-EIP). I tried to do this but I don't know where the CPS files are. Does anyone have any ideas? I have never seen these errors before with prior CX-One versions. I tried to upload some screen shots of the error pop-ups but for some reason the site isn't letting me upload images. Thanks.
