BUFFER CONTROL METHOD IN PLC MAP COMMUNICATION

摘要

In the PLC MAP communication, the buffer control method controls the limited buffer efficiently and increases the communication efficiency of PLC by excluding communication failure. This method allocates buffer regions for each station to receive data from stations and controls receiving buffer in reference to user's setup value. The control buffer consists of a transferring buffer(1), a receiving buffer(2), a physical layer(3) and an interface(4).
