STEP7 temperature in the boiler system
Abstract:
IT industry is developing rapidly, and lead humanity into the information age. As information technology and the rapid development of computer technology, programmable logic controller (PLC) in the field of industrial automation applications are more and more widely.The system for a boiler plant to study PLC-based control of the process control system of the structure to STEP7 as its core, the realization of the boiler temperature control.his paper introduces the characteristics of the Siemens programmable logic controller, application fields and development prospects, as well as the use of STEP7 programming software. During the design process, first of all, accused of using STEP7 hardware configuration objects, and then use STEP 7 programming to control the temperature of the boiler.
