SYSTEM FOR MEASURING GATEWAY FOR PLC AND DCS |
摘要 |
PURPOSE: A system for measuring a gateway for a PLC(Programmable Logic Controller) and a DCS(Distributed Control System) is provided to improve transmission speed from a higher system to a subsystem. CONSTITUTION: A gateway system(100) includes a transceiver(118) transmitting and receiving data of subsystems(116) through serial transmission; a central processing unit(106) controlling full-duplex data communication between the subsystem and a super-system(108) to be integrally processed through the transceiver, transmitting message write data to the specific subsystem after fixed waiting time has passed since the super-system inputs message write requesting data for the specific subsystem, and immediately controlling write confirmation data to be transmitted to the super-system if the specific subsystem transmit the write confirmation data; a memory part(101) storing various control data transmitted through the central processing unit; and an interface part(114) placed between a communication unit connected to a network(110) and the central processing unit for rapid data transmission with the super-system.
