Programmable controller and implementation method

Abstract

The invention provides a programmable controller and an implementation method. The programmable controller comprises a switching value input sensor, an analog quantity input sensor, an RJ45 communication interface, an RS485 communication interface, a starting switch K1, an emergency stop switch K0, control equipment, an intelligent touch display screen and a control module. The control module comprises a power supply circuit, a main control unit, a switching value input unit, a switching value output unit, an analog-digital interface unit, an RS232 communication unit, an RS485 communication unit, an RJ45 communication unit and a storage unit. For different application scenes, a user can carry out programming operation, a professional programming language or a downloading tool is not needed, a common user can select input, output and feedback variables for enabling, and the control function and the protection function of the system are achieved; a friendly human-computer interface is provided, so that the system cost is reduced to the maximum extent, the system reliability and stability are improved, and the requirement of a higher application scene can be met.

Description

technical field [0001] The invention relates to the fields of electrical control technology and computer control technology, in particular to a programmable controller and a realization method. Background technique [0002] In modern society, electrical control products have been developed for many years. Among programmable controller products, two types of product forms, PLC (Programmable Logic Controller, Programmable Logic Controller) and DDC (Direct Digital Control, Direct Digital Controller) have basically formed; The continuous development of informatization and intelligence in various industries has put forward higher requirements for controllers. New requirements have been put forward in terms of programmability, capacity, communication capabilities, and especially the ability to combine with information systems. The usage environment, usage method, and even user groups have changed a lot. [0003] In the fields of intelligent hardware, medical equipment, instrument...
