Embodiment

[0048] Such as Figure 1-4 shown.

[0049] A rapid PLC construction method capable of autonomously configuring hardware resources, comprising:

[0050] (1) generating a hardware resource configuration parameter table;

[0051] According to the customization requirements of PLC products, the PLC hardware determines the number and type of I / O points according to the control requirements and PLC functions, and realizes the construction of different types of PLC within the scope allowed by the CPU hardware I / O resources;

[0052] The method for determining the hardware resource configuration parameters includes:

[0053] (1.1) The selection of PLC I / O points should first consider the control requirements and take into account the spare margin; usually the I / O points are based on the actual needs of the input and output signals of the controlled object, plus 10% - 30% determined by the reserve amount;

[0054] (1.2) Develop PCB circuit board PLC-PCB according to I / O resource requ...

Abstract

The invention provides a hardware resource autonomously configurable PLC quick construction method comprising the steps that (1) a hardware resource configuration parameter list is generated; (2) thehardware resource configuration parameter list PLC-CS is downloaded to a PLC-PCB parameter configuration storage area FLASH, and the PLC monitoring program is downloaded to a PLC-PCB program storage area FLASH so as to complete construction of the PLC; and (3) the constructed PLC operates the implementation procedure; (3.1) the hardware resource configuration parameter list PLC-CS is read to complete I / O driving analysis and complete autonomous configuration of the hardware resources; (3.2) the PLC monitoring program is operated. Autonomous configuration of the hardware is performed on the CPUhardware resources to quickly construct and customize the PLC hardware, and customization of any I / O point number within the range of the CPU hardware resources can be realized through the configuration technology and research and development of series of safety PLC of different I / O point number and different communication modes can be quickly formed.

Description

technical field [0001] The invention relates to a PLC rapid construction method capable of autonomously configuring hardware resources, and belongs to the technical field of PLC hardware resource configuration. Background technique [0002] Serialization of PLC products refers to different customized development according to different I / O input and output types, number of channels, and communication modes. In the traditional way, it is necessary to develop differentiated software to realize it, which greatly increases the difficulty of development and has a development cycle. Long, poor software stability and consistency. [0003] Chinese patent document CN101303580A discloses a method for realizing a PLC controller supporting multiple CPU structures. The present invention includes two major parts, a core structure part and an application design part. The core structure includes three parts: PLC instruction frame, PLC engine structure and CPU platform structure. The PLC ins...
