Development of a Distributed Control System Based on PROFINET for SINUMERIK ONE

In contrast to centralized control systems, distributed control systems possess superior flexibility, reliability, scalability and maintenance convenience, when managing intricate tasks and keeping system stable. To actualize the intricate functionalities of machines and streamline the development and maintenance procedures, a methodology for constructing one kind of distributed control system based on PROFINET communication is devised here. This methodology is specifically designed for the development of field devices with Siemens SINUMERIK ONE systems, which are hardware configured and programmed via the automated programming software TIA Portal. This article focuses on the characteristics and establishment methods of the two communication modes for different real-time requirements in PROFINET IO communication, and introduces the building of device network in detail. By applying this methodology, practical verification was conducted on the bevel gear testing machine. The feasibility of the methodology was substantiated by the successful realization of the anticipated function and the system’s stable operation.
