Need Help on DH-485 networking

[i_avd]

HI! I'm student and I have to netwok some PLCs. I have 1 SLC5/03, 1 SLC5/02 and 2 micrologix 1000. I want to network them all in a DH-485 network. I also have the following devices: 2 1747PIC, 2 SLC500 link coupler (1747 AIC) and cables 1747CBLAM00, 1747C10..... my specific problem is that I want to know if I have to buy another device to serve as the concentrator or so, for the DH4-85 backbone. Can u help me?. I want to know how to do the connections. The 4 devices I want to network end up with a DH485 interface, and then what?.....
Which configuration should be implemented in each device in order to do the network?.

Thank you very much!
