PIC network over AC 220V

[boban]

Hello, I was searching this forum, but didn't found any valueable information about the communication between the PIC controllers over 220V AC. I found in BPB pro compiler interresting commands XIN and XOUT, looks very nice, but how I can use it for communication between the PICs connected to 220V? I've just want to switch on/off the bulb from the master PIC, but I don't want to use any other wires od wireless solutions. Thanks for ideas or links.

Use these devices with the X commands.

If you want to play you find datasheet for TDA5051 9600 kbps / 220V

Xin & Xout are rather limiting because of the low speed (60 bps) and limited number of commands. Plus you'll need an XM10 to send/receive.

Hello, so thanks to everyone for the posts. I played around and discoverred, that the best thing is to use the power modem TDA 5051. I am able to communicate between the two PIC via the power sockets. I build the remote controlled relay, simply I connected directly the serial line of TDA 5051 directly to PIC and it is working very well!!! So for those, who are interrested in to communicate via power lines use TDA 5051. Boban

My pleasure if my idea is good.All the best to you and I wish many good project's in future to you.

Yes, your idea with TDA kicked me to the right direction ))))
I am thinking now about the security of this solution, some kind of encryption or authentication, but anyway your idea was the best !!!
