Abstract
This paper presents a solution for the hardware implementation of EIA-709.1 Control Networking Protocol. It is the basic protocol of LonWorks systems used for the building system and the sensor system. The EIA 709.1 protocol has been implemented at the hardware level from physical layer to network layer to reduce the computing load on the CPU. VHSIC hardware description language has been used for the EIA-709.1 protocol. Other layers have been implemented using C programs on Intel 8051 processor. The protocol has been implemented using field programmable gate array technology and the commercial feasibility of the proposed solution has been performed through the communication test using the Neuron Chip of EIA-709.1 protocol. The designed core is usable as one of the intellectual properties and it is applicable to design System-on-a-Chip for various industrial controllers.
