Embodiment 1

[0042] A configurable PLC control system integrating display and control, including a platform layer and a terminal layer;

[0043] The platform layer includes a PLC program editing module, a variable management module, a hardware configuration module and an interface configuration module;

[0044] The terminal layer is PLC series hardware, which is used for: data processing and display, real-time control, fault diagnosis and alarm, PLC sentence list analysis, hardware configuration analysis and communication protocol analysis.

Embodiment 2

[0046] As described in Embodiment 1, a configurable integrated display and control PLC control system is different in that the terminal layer is Shanke PLC series hardware. The Shanke PLC series hardware (SKPLC for short) is a Shanke brand PLC product with independent intellectual property rights developed by the Shandong Provincial Computing Center affiliated to the Shandong Academy of Sciences.

Embodiment 3

[0048] As described in Embodiments 1 and 2, a configurable integrated display and control PLC control system differs in that the platform layer includes a core processing unit, an input and output module connected to the core processing unit, a communication module, a man-machine Interactive module and power management module;

[0049] The core processing unit adopts ARM-based microcontroller LPC2368; the functional interface is rich, and the performance is stable and reliable;

[0050] The input and output module is used for: digital input and output, analog input and output, high-speed pulse input and output;

[0051] The communication module is used for: realizing the communication between the platform layer and the terminal layer;

[0052]The human-computer interaction module is used for: displaying data read from the PLC, data analysis results, and alarm signals on the interface, and realizing parameter setting and manual control of the touch screen through the interface...

Abstract

The invention provides a configurable display control integrated PLC control system comprising a platform layer and a terminal layer. The platform layer comprises a PLC program editing module, a variable management module, a hardware configuration module and an interface configuration module. The terminal layer is provided with PLC series hardware and used for data processing and display, real-time control, fault diagnosis and alarm, PLC statement table analysis, hardware configuration analysis and communication protocol analysis. The configurable display control integrated PLC control systemis composed of two parts of a human-computer interface and a SKPLC terminal. The functions of PLC hardware statement table analysis, real-time control and fault diagnosis and alarm are realized, and the functions of interface configuration and hardware configuration analysis are additionally arranged. Differentiated customization and development of the integrated PLC control system can be performed according to different I / O input and output types, path number and communication modes of different models of PLC. The functions of logic program editing, variable management, hardware configurationand HMI configuration of the integrated PLC can be realized through the integrated PLC control system.

Description

technical field [0001] The invention relates to a configurable PLC control system integrating display and control and a control method thereof, belonging to the technical field of PLC control equipment. Background technique [0002] After years of development, domestic PLC has also developed to a certain extent. Shanke PLC (SKPLC for short) is a Shanke brand PLC product with independent intellectual property rights developed by Shandong Provincial Computing Center affiliated to Shandong Academy of Sciences. The SKPLC series is divided into different models according to different application requirements. The number and number of ports between different models are different. In the traditional way, different software needs to be developed to realize it, which greatly increases the difficulty of development, and the development cycle is long. Software stability and consistency are poor. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the pres...
