CANBus network Interface working

Hello Everyone,
 
 I am new to the CANBus and i want to develop CANbus network for multiple nodes as per below.
 
 1. I have one master node which send data to the slaves nodes and received data from those nodes.
 2. I have more than 4 nodes which works as slave or master nodes.
 
 Now the question is how slave 1, slave 2 and other slaves know the data send from master nodes is for that node only. does salve has to provide some hardcode ID ??
 
more specific to say if i send data from the master to slave 1, then  how slave 1 know that the broadcast data is for slave 1 only. 
 
Please reply on this query. 
 
Thanks

    It works now,  after giving the different identifier IDs to all four slaves.

    In CAN networks there is no addressing of recipients in the conventional sense,
    messages that have a particular identifier are transmitted instead.
    Thus, a sender sends a message to all CAN nodes and each one by its side
    decides, based on the identifier received, whether or not to process the message.
    The identifier also determines the intrinsic priority of the message, when competing with
    access to the bus.
