Networking several BeagleBone Blacks using power line communication. Beagle Bone Black uptime?

What is the expected up-time of BBB?  If a board crashes, will it reboot and launch processes on its own, or would it require some physical maintenance (pressing a restart button?).

I want to create a smart industrial light system using BBBs.  Each BBB will be enclosed in an industrial LED overhead lamp.  The BBBs will gather input from some sensors (temp, light), control the LED lights, and send information to a central server over Ethernet using power line communication.  The BBBs will also receive commands from the central server (change light intensity, etc.).

If I assign IP addresses to each BBB and then connect them as follows:

BBB_1 -> PLC -> powerline <- PLC <- BBB_2

BBB_3 -> PLC -> powerline <- PLC <- ... BBB_N

for N BBB's, would I be able to ping one from another?

I understand that PLC transmission distance will be a problem.  The distance between each BBB may be up to 150 feet.  This projet, conceptually, could sale to hundreds of nodes.  What could be some approaches to solve this?  Any help / advice / links to reference material is greatly appreciated.

Thank you.

    Hi Thomas,

    The up-time of an embedded system (not BBB only) strongly depends on the software running on it and depends on the hardware of course. The behaviour of a board after crash is specific and depends on the reason causing it (in some cases board can reboots in other case stuck).
    The IP networking via powerline requires additional hardware. I think the distance of 150 feet would not be a problem but it depends of the choice of hardware for powerline connection.
