HI, I have a question as it relates to redundancy. I have upgraded a project that previously had a local and remote HMI and was configured with the appropriate primary and secondary computers, IO servers, alarms servers, and trend servers in a single cluster.
However, they have opted to remove the second HMI, leaving only one. The control device I am communicating to (Micronet) has two CPUs, and I want to be able to communicate to the second controller if the first one goes down. I only have one ethernet port on the HMI though, so I'm wondering if it is possible to configure two data paths from that single port. I tried a few different configurations that I thought would work: adding a the secondary IO server to the primary computer (threw an error about the IO server needing a unique IP address) and adding a secondary device to the Primary IO server (also threw an error about the standby device needing a primary on the same cluster--not sure this error makes sense to me).
Any thoughts as to if this is possible and where I am going wrong on the configuration?
