Microcontroller with multi client communication protocol

[2Wires]

microcontroller communication protocol

Hi,
I am looking for a microcontroller which already has an implementation for multiple client communication.
I have an serial communication bus (powerline with ST737HS1) and I want to attach some clients to it. Then I want to ask clients for data and send control data.
Which microcontroller has such an implementation and where to get some infos?
Thanks

snap protocol 485

Hi

I think you can use any microcontroller and rs 485 or rs 422 (full duplex)

communication protocol in a master - slave configuration.

this type pf connection allow you to connect 1 master and many slave's

bobcat1,

RS485 and RS422 are not a communication protocols. These are only specifications for the link layer of communication protocol.


2Wires,

Try a search for "CAN+microcontroller" in google.

multiple client communication

you can use modbus protocol on rs485 physical layer.It can support up to 247 slaves.(one master).

Hi,

8051 UART port can provide multi-client communication function.

+snap +protocol +implementation

Hi,
thank you all for your suggestions.
Finally I took a ATmega and implemented my own protocol. So I don't have too much overhead bytes and I just use what I need.
thx and cya

abstract on multi client communication

Hi

If you still want to have a look how I did "one Master/multiple Slaves" with a 80C535 you can check my homepage and look for the BenBus. Based on RS485 with a homemade protocol. Written in Bascom-8051.

Have fun

what is meant by multi client communication

I have used this PLM in the past. You can implement SNAP protocol to communicate the devices. In my case I used a HDLC implementation. Here I have attached a document about SNAP. Regards.
