HelloTrueHeart,
You didn't mention something about memory cards and synch. modules. Please double check the part numbers and versions of the 4 synch. modules and also the memory cards. Can you try a small project with default CPU settings and a small program and download it to work memory of CPUs without memory cards? Do both CPUs work redundantly in this case? Can you swap synch.modules and see if CPU in Rack 0 is going to stop instead of CPU in rack 1? Best regards, H-H
