Embodiment Construction

[0191] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0192] like figure 1 Shown: Aiming at the requirements of cross-platform application of PLC control system, based on HTML_WEB gateway, WebSocket and UDP communication protocols, a communication link between the three is built.

[0193] like figure 2 As shown: the present invention has multiple application modes. One is that a local area network can be established through WIFI, and any intelligent terminal can be accessed across platforms to realize on-site control of the PLC control system; Access to realize remote control of the PLC control system.

[0194] like image 3 , Figure 13 Shown: Based on HTML5+CSS+JavaSc...

Abstract

The invention belongs to the technical field of cross-platform Internet of Things application, and discloses a PLC cross-platform control method based on an HTML_WEB gateway. The method comprises: based on a self-defined data communication format, performing cross-platform webpage interface and communication related function design by utilizing an HTML5 + CSS + JavaScript programming design technology, downloading the cross-platform webpage interface and communication related function design to a gateway, designing a PLC series function block, and downloading the PLC series function block to aPLC; and finally, realizing transparent communication among the webpage, the gateway and the PLC, and any intelligent terminal can access the PLC control system in a cross-platform manner. A data communication link is constructed, and a user can carry out function expansion according to own function requirements. By means of the method, engineering personnel only need to design a cross-platform webpage interface, PLC programming and downloading are not needed, the PLC can be applied to achieve the input and output basic functions of digital quantity and analog quantity, and convenience is brought to user application.

Description

technical field [0001] The invention belongs to the technical field of cross-platform Internet of Things communication, and in particular relates to a PLC cross-platform control method based on an HTML_WEB gateway. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] The PLC control system has always been in the leading position in the industrial automation control industry and is widely used. In the PLC control system, the human-machine interface (HMI) is widely used. At present, there are mainly two ways to design the human-machine interface (HMI). One is to design the HMI based on configuration software. The designed HMI can only run on the upper computer, and cannot cross-platform through smart terminals such as tablets or mobile phones. Access; the other is to use touch screen-related configuration software for man-machine interface design. The designed man-machine interface can only be downloaded t...
