Abstract

The invention provides a Profinet protocol-based communication method for intelligent equipment and a peripheral device. The method comprises the following steps of S1, configuring system software andhardware requirements supporting a Profinet protocol in the intelligent equipment, and designing a configured table; S2, drawing an electrical schematic diagram and completing wiring connection; S3,writing a PLC / PMC interface program for communication between the intelligent equipment and a peripheral device, and downloading the PLC / PMC interface program; S4, writing an HMI interface program related to the PLC / PMC data, and downloading the HMI interface program; S5, importing a GSD file of a peripheral device through Profinet software; S6, configuring data information of a peripheral devicethrough the substation module IODD file and the table information, and downloading a configuration file; and S7, if the HMI display data is consistent with the internal data of the peripheral device,normal communication between the intelligent equipment system and the peripheral device being carried out. According to the communication method, through a Profinet protocol, internal variable data ofa peripheral device can be directly read, analog quantity to digital quantity can be rapidly converted, and comprehensive efficiency of equipment communication is improved.

Description

technical field [0001] The present disclosure relates to the technical field of industrial control, in particular to a communication method between an intelligent device and a peripheral device based on the Profinet protocol. Background technique [0002] The CNC machine tool automatically processes the processed parts according to the pre-programmed processing program. Therefore, a CNC machine tool is an automatic machine tool equipped with a program control system. The control system can logically process programs with control codes or other symbolic instructions, and decode them, express them in coded numbers, and input them through information carriers. CNC device. After calculation and processing, various control signals are sent by the numerical control device to control the movement of the machine tool, and the parts are automatically processed according to the shape and size required by the drawing. [0003] In order to understand the working condition of the CNC m...
