JCI M3i

[NSimao]

Has any one worked/installed this system? What are your opinions?

[GYUR22]

I have some installations
My opinion - works well
M-Graphics - perfect
other parts M-alarm, M-Trend, etc- not so convinient
EDE OPC- good convinient tool
BACnet OPC - I have not BACnet systems yet (on JCI controllers), but looks like working with NAE and FX (if you want to use BACnet you should read docs)

imho: If you have not a big system (~1000points) without cool graphics demand you can use NAE35
