Abstract

The present invention provides an EtherCAT bus control method and device applied to a system comprising an EtherCAT master station and a slave station, wherein the method comprises the steps of analyzing a preset control instruction code based on a Basic platform to obtain a control parameter; based on the control parameter, determining a control flow corresponding to the control parameter; sending the control parameter to a driver of the slave station via the EtherCAT master station, so that the driver drives a motor to execute the control flow via the control parameter. Therefore, the control method and the control device of the scheme of the present invention control via the digital instructions, overcome the defects in the prior art, are good in expansibility, are flexile to use, and avoid the interference of using the pulse output and the defect that a control distance is short.

Description

technical field [0001] The invention relates to the field of control, in particular to a control method and equipment for an EtherCAT bus. Background technique [0002] Basic (Beginners'All-purpose Symbolic Instruction Code) platform is a kind of independent motion control system platform based on text programming. Its main application feature is that it can run independently without a PC (personal computer, personal computer). And in view of the universality and convenience of high-level language programming, the platform also supports multiple programming methods, as well as mixed programming, including Basic, PC high-level language programming, and G code (that is, the instructions in the NC program) programming. Compared with the traditional PLC (Programmable Logic Controller, Programmable Logic Controller), the motion control function of the control system is more powerful, and there are many programming methods. [0003] At present, the Basic platform realizes contro...
