PLC lighting control

Other Parts Discussed in Thread: TMS320F28PLC83, TMS320F28069, AFE031

Hi,

My requiremenst are still a little fuzzy but here is what I know

Street light control with power line communication. (Controller to be in the light pole base)

125 degrees C (heat dissipation will be an issue).

Lights are broken up on the 3 phases, 230Vac COMMON neutral. (yea I know Common neutral is not code in the USA)

Approximatley 70,000 lights to be controlled.

I don’t know the distances yet….

I'm not sure which standard yet I will have to follow, G3, Prime, or our prime lite.

I'm currently looking at the TMS320F28PLC83 as well as the TMS320F28069 and the AFE031
( I need to run at 125C)

Given that I have 70,000 nodes is there a particular standard you would recommend? how easy/practical is it to have 70,000 unique addressable nodes?

Cheers

Calum

    Hi Calum,

    None of the standards support that large of a network directly.  A network of about 1K is more realistic based on what exists today.  To create a larger system, concentrators would need to be used and you'll definitely need a significant number of concentrators to support 70K end points.

    From a standards standpoint, G3 is generally considered to be more robust whereas PRIME offers higher theoretical data rates.


    Thank you,
