A PLC programming auxiliary system and a method thereof are provided. The system comprises: a web server providing a complex algorithm for programming PLC, correctness checking of the programming and user logic compilation functions; a plurality of client computers connecting with a web server and the programmed PLC devices via a network link. When a client computer is linked to the website server by a user, a web browser on the client computer requests from the web server to download client programming software for programming an appropriate PLC device, and the client programming software for programming the appropriate PLC device is executed within the web browser on the client computer, to enable the client computer to configure the PLC device and program the user logic through the client programming software for programming the appropriate PLC device, and the client computer implements an interface connection and an interaction operation of the web server with the user through the client programming software for programming the appropriate PLC device.

An automation interface is provided for interacting with industrial controllers. The automation interface provides for programming, editing, monitoring and maintenance of industrial controllers programmatically from a local or remote location. The automation interface component is adapted to communicate with industrial controllers by integrating a computer process interface library into the automation interface component. The computer process interface library exposes the automation interface component to client application processes, so that the client application processes can communicate with the at least one industrial controller programmatically. The automation interface is provided with functionality for downloading, uploading and programming of control programs to the processors of the industrial controllers.

A website system and mobile application showing the lift status of drawbridges uses sensors, a bridge operator, a website and a mobile application. The sensors detect whether the bridge is raised or lowered and then communicates the information to the managing entity of the website and the mobile application. The bridge operator provides additional information regarding the condition of the bridge, which is updated on the website. The website provides the public with up-to-date information, alerting users regarding the current raised or lowered status of the bridge, and may be accessed using the mobile application.

Systems and methods for controlling electric vehicle chargers using central control consoles for controlling and communicating with industrial equipment. The electric vehicle chargers operate as clients in a client-server configuration with a dedicated OCPP server. The OCPP server communicates with a control console using either of two communications pathsone path uses a direct HTTP connection with the control console. For this path, the control console operates as a web-enabled client. For the other path, multiple communications protocols are used and conversions between these protocols are effected using a conversion module and a MODBUS server. The MODBUS server communicates with the OCPP server. The MODBUS server also communicates with the control console by way of the conversion module and a control server. The control console is thereby able to control multiple pieces of industrial equipment along with the electric vehicle chargers without needing to be compliant with the OCPP protocol.

In order to output a given text string from a ladder program that has been analyzed, this PLC device is provided with a text data output unit for reading text data from a storage device, a display unit for outputting the given prescribed text string to a display device, and a communication unit for carrying out text communication with a network server by means of a prescribed command. In addition, the text data output unit is able to implement general-purpose protocol communication (HTTP communication) with a PLC program by determining, on the basis of a keyword included in the text data, whether the text data is to be output to the display unit or the communication unit, and outputting the text data to the display unit or the communication unit, on the basis of the determination result.
