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 paths—one 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.

A display and operating unit having a web application for operating a field instrument and a method of operating a field instrument having a display and operating unit having a web application, wherein the display and operating unit is connectable to the field instrument; wherein at least one parameter of the field instrument is visualized on the display and operating unit by means of the web application and a parameterization of the field instrument s made possible and the web application for the visualization and/or parameterization is executed in a browser; wherein the browser is executed on the display and operating unit; and wherein the browser and/or the web application has/have an interface with which direct access to components or operating system components of the display and operating unit, to components of the field instrument and/or to external units is carried out.

A method and a programmable controller for accessing data or functions, the data being stored in a database of the programmable controller and the database being assigned to an application program of the programmable controller, and a web server of the programmable controller being accessed by a client via the network protocol, where at least one program module of the automation program of the programmable controller is assigned to a web service of the web server, and where execution of the program module is initiated by the web service such that flexible and simply implementable access to data or functions of the programmable controller is therefore possible, and the access to the data or functions can be controlled load-dependently.

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.

Example implementations described herein are directed to a change over detection system and method. Such example implementations facilitate updating the information of the production line in an Internet of Things (IoT) system to the latest version. Through the example implementations described herein, device rearrangement in manufacturing field can thereby be detected.

A method for optimizing data transmission in an automation system between a control device and at least one cloud system, as well as to a corresponding control device, a corresponding cloud system, and a control system. The method includes at least the following steps: determining a data transmission characteristic of at least one transmission path that is available for data transmission by means of a first and/or a second determination component; analyzing whether the data to be transmitted can be transmitted, based on the data transmission characteristic determined; selecting at least one action from a set of actions in order to adapt the data to be transmitted and/or the transmission path if the data to be transmitted cannot be transmitted, so as to allow the data transmission; and performing the at least one selected action.

A method for operating a fieldbus controller (2) having a plurality of I/O modules (4) is provided, the fieldbus controller (2) being coupled to a valve assembly (6) via the plurality of I/O modules (4). The method includes providing a user interface (8) for wirelessly operating the fieldbus controller (2), wherein providing the user interface (8) includes: providing a configuration interface (14) for configuring an operating mode of the plurality of I/O modules (4); providing a monitor interface (16) for reading status information from the plurality of I/O modules (4); and providing a control interface (18) for controlling a state of the plurality of I/O modules (4), the state of the plurality of I/O modules affecting a state of the valve assembly (6).

The present invention relates to a method, device, and system for transmitting a program and parameter to a PLC. An adapter connecting to a port of a PLC allows an operator to simply (i) log in on a cloud server with use of a mobile terminal on which an APP is installed, (ii) download a written program or parameter, and (iii) transmit the program or parameter directly to the adapter wirelessly to transmit the program or parameter to the PLC via the adapter. An alternative embodiment may be arranged such that the cloud server transmits, to an APP of the mobile terminal over a mobile network, an instruction on what data to sample and that the APP accesses the PLC via the adapter, obtains the data, and feeds back the data to the cloud server. This simplifies the operation for updating and maintaining a program and/or parameter of a PLC and reduces costs.
