Hello R J, My first question, do you have RAM or EPROM? 1- Read the diagnostic buffer of both CPUs. 2- Upload program from both CPUs and compare them to each other (If you have flash memory). 3- Make sure that both CPUs have the exact firmware version and if not, download theright firmware to the CPU in STOP. 4- Download your program and try again. Best regards. H-H |

Hello R J For such complex issues need save diagnostic buffers of both CPU and attach to thread. In this case, you save time and get more accurate recommendations |

RJ, You may look here of Late's message for Update Firmware-If you are looking to update without stopping your both Redundant CPUs. |
