Hi,
Looking at installing a L8x redundancy system and have perused the manual.
Yep version 1 (beta..) on L8x, probably not the best idea, as well as the limitations associated with it, embedded Eth port disabled, single controller per chassis etc...
I am currently using produce/consume unicast across subnets for interPLC communications and this is an issue. So to avoid creating a flat layer 2 subnet across the site for communications purposes I assume I would have to revert to using messaging and some code to determine which read MSG data to use when reading from the two redundant controllers (without IP swapping). Possible the read MSG from the secondary may fail anyway.
I could create a single subnet for the two redundant controllers to permit IP address swapping. Assume the MSG function may work better (more seamless) with this approach, and possibly the SCADA with a single IP to hit. Although I am sure the SCADA will have some lag when failing over.
Is anyone on this forum running without IP swapping or using MSG rather the produce/consume who can add to this?
