Wires
One block is connected to another block with the help of wires. All data transfer between the output port of one block and the input port of another block is done using wires. All connections must be made between compatible types. See Wires and Blocks for detailed information.
Note: 
The network of blocks in a model cannot contain any kind of cycles. See Wire restrictions for more information.
