Hi

I have a several modbus RTU and TCP slave devices. I want to make a network (I mean combine all them) and send the information to a master with one Ethernet cable. what devices should I use for it (I mean is there any switch that receives both RS-485 and Ehternet as the inputs and gives ethernet output)?
 
You will need at least one modbus RTU/TCP gateway depending on the RTU slaves the gateway can handle. Google for suppliers of Modbus RTU/TCP gateways.

I have never seen gateways with more than 2 ethernet ports (This doesn't mean they don't exist) so you probably also need an ethernet switch.
