Logic and Motion Integrated Controllers

Abstract

The invention discloses a logic and movement integrated controller. The logic and movement integrated controller comprises hardware and firmware, and is provided with programming environments according with the IEC61131 and PLCOpen standard. The hardware takes a DSP chip and an FPGA chip as the core and is used for achieving movement control and logic control; the firmware is software solidified in FLASH of the DSP chip and used for achieving the movement control function and the logic control function. The logic and movement integrated controller can achieve the logic control function and the movement control function at the same time, high-speed communication can be achieved between logic control and movement control, meanwhile, hybrid programming of logic control and movement control can be simultaneously achieved in one programming environment, the programming environments comply with international standards, ambiguity can be reduced, and usability is improved; compared with PLC and MC separation implementation schemes, stability and reliability are higher, and cost is lower.

Description

technical field [0001] The invention relates to the technical field of equipment control, in particular to a logic and motion integrated controller. Background technique [0002] The numerical control system is the core component to realize the intelligence, networking and integration of modern equipment, and it plays an important role in improving the function and performance of the equipment. The CNC system of modern equipment usually needs to perform logic control and motion control at the same time, integrate advanced detection technologies such as machine vision, and be responsible for human-computer interaction, etc. Among them, logic control and motion control are the core functions of the numerical control system, and are the key factors that affect the core indicators such as the speed and precision of the equipment. In the traditional control architecture, independent controllers are used to realize logic control and motion control respectively. Among them, PLC (p...
