Hello.
I'm not an electrician, but I'm trying to search about something but i couldn't find the exact thing about it.
Can you help me what do you guys call this thing?
vb-jpg.31577

I have 5 devices and 2 switches on one side and another 5 devices and 2 switches on the other side and they are connected by 4 core wire, for example if i click on "Switch 1" to switch "Device 2" & "Device 5" & "Device 9".
And if i click "Switch 4" to switch "Device 1" & "Device 3" & "Device 8".
Is there a chip or something like "A" in the image that if i click on "Switch 1" it will switch "Device 2" & "Device 5" and sends data to "B" to switch only "Device 9".
Because i tried to do it in the normal way i ended up with 16 wires between the 10 devices, can i achieve that with 4 core wire?
I'm asking because i saw that thing in my video intercom system the indoor unit and the outdoor unit they only connected by 4 wire core with multiplexing inputs.
Sorry for my bad English.

One industrial example of it is, is a two PLC systems that communicate over Modbus.
There is also CANbus used in automotive industry and also it can be individually made by a pair of microprocessors communicating via RS232/RS485 etc.

Packetizer, Ser-Des (serializer-deserializer), lotsa recently-developed names. But the original name is a multiplexer. Originally developed to push multiple independent telephone conversations down a single pair of wires, you can use either analog or digital signal techniques. For simple 1-to-1 control setups (press button #1 here, relay #1 closes over there) there are modules on ebay. Your doorbell uses custom-programmed microcontrollers to do all of the logic, send and receive the data, etc.

To start with, work up a truth table showing the outputs for all 16 switch combinations.

It all depends on the application, an extension of the PLC function is a SCADA system.

Thank you Minder and AnalogKid.
It seems PLC is very advance thing, i thought it was a simple thing, i probably will stick with the traditional method or try to use Shift register.
Again thank you guys.

If you have ever used a small micro-processor they could do it very easily.
