摘要
针对分布式控制系统在工业生产中快速、高效、灵活的诸多优点,设计了基于CAN总线的工业I/O模块,此模块可广泛应用在分布式控制系统中数字量模拟量的输入输出,并且提供安全冗余,模块以C8051F040增强型51单片机为核心,对实现分布式控制的CAN通信模块进行详细设计。在实际应用中,该分布式CAN I/O模块运行良好,而且通信实时稳定。
Open distributed control system production automation has been increasingly widely used in production automation. A industrial I/0 modules based on the CAN bus is designed to meet the trend in manufacturing plants which is to operate faster, more efficiently and more fle-xibly. This modules provides input and output function blocks in a distributed control automation systems. In particular, detailed design the realization of distributed control of the CAN communi-cation modules. In practice,the distributed CAN I/O modules designed flexibly to run well and it fullfills stable and real-time communication.
