When installing a brand-new CPU during the production operation of the system,
-do not connect the network cable between the master and standby CPUs.
After the CPU and CRA are all fully operational, connect the network cable to construct the ring network.
-Alternatively, in accordance with the operating procedure outlined in the user manual,
you can first download the program to the brand-new CPU independently, then integrate the CPU into the on-site control system.
