Title  WINCC-based Control Systems for altitude bin                                                                   
Abstract
With the development of computer hardware and software technology and automation products showing a miniaturization, network, PC, the development trend of open and low cost, and gradually formed a variety of standard hardware, software and network structure system. Monitoring configuration software has become one of the bridges and ties, it is an indispensable key component in automation system integration. In real life, people of transportation safety and environmental adaptability of the proposed higher requirements, set at an altitude of positions of various environmental conditions, a simulation test is carried out. In this way, the actual product testing various properties. Therefore, the construction of an automated warehouse test room must be put on the agenda.
Motomi Kura control system design is the use of SIEMENS WINCC configuration software and S7-300 SIMATIC series PLC to design the altitude chamber test room temperature and humidity and pressure control system. At first, the process flow and functional requirements of the system are summarized, and the overall design scheme of the system is improved. Secondly, through the WINCC configuration software to complete the design of the host computer, including alarm records, variable configuration, cross index and user management interface.
