Can someone explain to me how the SFC module works in a redundant system? I would like to know what happens when a long running process is executing and the master gateway suddenly goes down. Are both the master and the backup gateway in sync at all times? Does this sync happen at defined intervals? Are internal SFC chart properties updated between the two gateways as soon as they are changed? What happens when the master goes down and then comes back up? Does it sync with the backup and then take control of the SFC charts again?
I’m looking into getting this module to do some long run process stuff (maybe 8 hours or so) and I want to know a little more in depth how this is handled for a redundant system. Thanks!
