Installs the Ex-dinning Car Multi-way Movement the PLC Control

Abstract: This article introduced one kind based on the USS communication protocol attire ex-dinning car movement system. Programmable controller PLC through the RS485 connection, realizes to the scene equipment control, reduces the system wiring effectively the complexity, has avoided the scene many kinds of electromagnetic interference, sharpened the ant jamming ability, the article elaborated the system composition and the principle of design, and analyzed PLC to use in this kind of process control system the superiority, and has compiled the operating procedure with the programmable software.
