摘要

With the increasing need for the bus-field communication with the multiple devices at a time, in a data acquisition system and in various other fields like automation, there arise the need of the system that does this and prove to be reliable and have a fast communication system. The paper presents the design of the system that can have a multi-point communication, master-slave communication, in which there can be multiple slave and one master at a time. And in this the communication is just not restricted to the master and slave of the one net-work, they can communicate to the master and slave of the other network. This system got the two-sided communication. Controller asks for the status and results and slave responds to the request and its re-sult's controls the further communication. The system consists of Cortex controller (Cortex M3), which is of 32-bits ARM processor, that provides speed to the sys-timothies system implements MODBUS communication protocol for the communication between master and slave and uses RS485 for communication inter-face between devices. Here out of the two mode ASCII and RTU, available for the communication in MOD-BUS, In this paper RTU mode is implemented as it is faster than the ASCII mode.
