Posted 8 Jan 2020 i am a newbie on Omron PLC's. I have a CP1H with a bad I/O port and I want to backup the program and then download into a new CP1H via the memory card. Where can I find the documentation that illustrates how to do this procedure? Thanks in advance, danvp. Share this post Link to post Share on other sites
