Has anyone here ever attempted to create a system with redundant Netlinx processors, and if so what was the best way you came across to handle it? Specifically, I have a building where I need to control lighting, shades, etc. The customer requires redundant processors with automatic failover, and I'm thinking about the best way to do this. Obviously, I will need the ability to either switch the control port wiring from one master to the other, or multiple control interfaces on the controlled devices, but I don't see much problem there. The real issue that I see is in maintaining status of each processor in the other and having the panels switch from the primary to the backup in the event of a failure. I'm thinking that I should just set up a polling mechanism in each to verify status of the other, and only have the backup process panel events if the primary is offline. Also, I don't know I should have the backup processor telnet to the panels to change the Master IP on them, or if there is a better way to handle that part. Any ideas?
