Abstract

The invention provides a compiling method of an embedded PLC and an embedded system. The method comprises a step of obtaining a first request which contains equipment information and port information, wherein the equipment information is information corresponding to equipment connected with the embedded PLC, and the port information is information of a port of the embedded PLC connected to the equipment, a step of determining a corresponding protocol in a pre-stored protocol library according to the equipment information, a step of carrying out compiling to obtain executable files corresponding to the equipment and the port according to the corresponding protocol, and a step of allowing the embedded PLC to execute functions corresponding to the equipment through the port according to the executable files. In the scheme, the embedded PLC can save less protocols, for example, only a necessary communication protocol is saved, data which needs to be stored by the embedded PLC is reduced, and the storage space of the embedded PLC is saved.

Description

technical field [0001] The invention relates to the field of industrial control, in particular to an embedded PLC compiling method and an embedded system. Background technique [0002] PLC (Programmable Logic Controller) refers to a programmable logic controller. Embedded PLC is a development method using PLC graphics for special-purpose controllers. It makes full use of the powerful processing functions of existing embedded processors, customizes various special-purpose controllers on demand, and adopts graphical development platforms (LD, SFC, FBD, etc.) for software development of dedicated controllers. [0003] In the existing related technology, when the embedded PLC needs to be connected to various devices, all the protocols corresponding to all the devices are stored in the embedded PLC in advance, and the configuration is performed according to the actual connected devices during use. [0004] When there are many types and models of connected devices, a huge number...
