Is it possible to communicate over dc power line of 12V as a master slave rs 485 communication.
Is there any specific IC's available.
If possible please tell me how to do that?

Try SEARCH in this forum.
There was similar topic some time ago: "RS-232 over power line"
In any case you will need Low-pass-filter for DC and High-pass-filter for communication. This can be accomplished by simple L-C combination.. DC power choke of, say, 1mH as power filter, and (...)

Did anyone doing project using this PLC before?? I am currently plan using this PLC as communication medium for the power measurement it suitable?? I will use the PC interface to control home appliance and measure the power of home appliance with using PLC as communication. Hope can get some comment at here.

I'm having a project which need to send the Video signal at the rear side of the car using the power line communication over DC.
1) Can the Video be able send through the PLC over DC with high data rate? We are targeting on 640x480, 16bit, 30 Frame.
2) If the video signal can be send (...)

I don't think that it works without modulation, similar to PLC (power line communication) techniques.

just an easy idea:
On your power supply side you need a resistor and a differential amp
to measure the current through the supply lines.
On the ?C side you connect a port pin to a transistor that will draw some current from the power lines.
thats all for unidirectional communication.

Hi, has someone any kind of experience or information about
implementing a communication over a dc power bus. In particular that
dc bus is the output (700V) of various step-up machines that are in
parallel elevating the voltage of independent photovoltaic strings in
order to be the input of a three-phase inverter to be the (...)

I will use PLC ( power line communication ) for remote control . I must use power cable ( 220 Vac ).
There are many PLC modules and IC's . But all pruduct support sending very big data ( 1-5 Mbps ).
But i need to transfer only one bit data.
Is there any simple methode for it.
I will send only (...)

This chip is intended for AC communication. I don't think it will work over DC lines since you need to couple a signal through a transformer. You'll need a different approach for DC communication -- perhaps 1-wire communications. Our company uses a technique of modulating the DC power (...)

Did anybody use the infrasys power line communication IC over dc line.
I am using this IC and facing some issues.
When i am using a single master and single slave,the working is good.
But when i include another slave, communication is not good. Neither slave 1 and slave 2 not working (...)

I think you are talking about power line communication (PLC) used in Building-Home Automation systems (BACnet).
Search in EDAboard for DC-Bus or PLC.

Have anybody succeed with the power line communication over a dc line of about 12 -36 V.
If so, could you please tell me the IC which you have used.
Also i have given my planned system here where master will query and receives the data from the addressed slaves (number of slaves around 10 to 15) (...)

I'm reposting a previous doubt since i think i ve got some more information of the situation now.. :)
I'm working on a PLC communication AC/DC converter specifically a fly back topology converts the input power to DC voltage for the rest of the circuitry operation in the unit.
The P & N wires that are coming to the AC/DC conver

A subsytsem like a sensor needs to have a power supply and the option to communicate data. To accomplish this with two wire the supply line must be modulated. This modulation is detected an demodulated. One example over the AC power line is power line (...)
