hi

I use PUT/GET to communicate with the redundant 1500 system, and there is no problem when there is only one redundant 1500 system.However, when there are multiple redundant 1500 systems, it is necessary to consider the ring network problem and set up a ring network manager. However, CPU1500 in redundant 1500 systems must be the ring network manager. I am not sure whether to consider using PN coupler.
