Abstract

The invention provides an information publish device of production line equipment controlled by a programmable logic controller (PLC) based on a hypertext markup language (HTML). The device provided by the invention is characterized in that a central processing unit (CPU) is adopted as control part; the CPU is connected with a memorizer; the CPU is connected with a computer network interface; the CPU is connected with the physical interface of the PLC for the production line equipment; the memorizer comprises a network interface zone and a user zone; the network interface zone comprises a communication protocol and a memory mapping list, a transmission control protocol / internet protocol (TCP / IP) module and system software, wherein the communication protocol and the memory mapping list access to the PLC of the production line equipment; and the user zone comprises an HTML code module, an access authority list and a PLC communication parameter module. An HTML webpage is adopted to store a man-machine interaction interface containing PLC data, so that a computer in networks can perform access so as to realize human-machine interaction by means of webpage operations. Based on the communication protocol of the PLC and the memory data structure of the PLC, the system software calls subfunctions in accordance with the memory mapping list so as to obtain or modify the memory data of the PLC, and results are stored in the mapping list. The corresponding data in the memory mapping list is embedded into a webpage which is complied by means of HTML codes so as to form an integrated human-machine interaction interface.

Description

technical field [0001] The invention relates to an HTML-based PLC-controlled production line equipment information issuing device, which belongs to the technical fields of HMI and human-computer interaction of industrial control systems. Background technique [0002] The PLC system is widely used in the current industrial production for the control of equipment and production lines. Using PLC can easily save the PLC operation and key processes, and query through special software and hardware systems. [0003] In order to grasp the status of the equipment in time, it is necessary to frequently query the historical data recorded in the PLC to confirm whether the equipment is abnormal. However, a special software system is required for the query, and only a small number of professionals can do it. Usually, it is necessary to arrive at the PLC site for query. The monitoring system made by the bus system and a special computer can remotely query the status information of the PLC...
