Hallo
Can I use flexlogix CPU & i/o for cpu redundancy, i/o diagnostic,communication redundancy & power supply redundancy, if yes what will be the congiguration.
(I/o in CPU panel DI:-45 Nos. DO:-41Nos. AI:- 5Nos. AO:- 8Nos.
i/o in remote panel DI:-32Nos. DO:40Nos.)
How long Devicenet communication goes? I have to use it for 500Mtr.

I don't believe FlexLogix can be used in a redundant system. 500 meters is the maximum trunk length at 125K. Don't forget you drops can only be 6 meters long and you cumulative drop must be less than 156 meters. These lengths are lower for 250K and 500K. Goto
