Abstract

The invention discloses a program development method and system for a multi-core programmable controller. The program development method comprises the following steps: S1, a master core module establishing communication connection with an upper computer module through a first communication channel and establishing communication connection with a plurality of slave core modules through a second communication channel; S2, the main core module obtaining a programming information packet and a program packet sent by the upper computer module; S3, the main core module controlling and distributing the program package according to the programming information package, judging whether the program package belongs to the main core module or not, and copying the program package to a user program area of the main core module if the program package belongs to the main core module; and if not, the main core module forwarding the programming information packet and the program packet to other specifiedslave core modules through the second communication channel, so that the slave core modules copy the programs to the user program areas of the slave core modules.

Description

technical field [0001] The invention relates to the field of industrial control, in particular to a program development method and system for a multi-core programmable controller. Background technique [0002] PLC is widely used in the field of industrial control. Traditional PLC is based on single-core microcontrollers. It is widely used because of its simple structure and low cost. However, due to the limited processing capacity of single-core microcontrollers, it is difficult to achieve complex logic control and work efficiency. Low. In order to make up for the above defects and meet the current increasingly complex industrial control requirements, PLCs based on multi-core microcontrollers with higher performance have emerged as the times require. The way of multi-core parallel processing greatly improves the working efficiency of PLC. [0003] At present, multi-core microcontrollers are mainly developed in emulator mode. The development environment of languages ​​such ...
