Disclosed is a field device adapter for wireless data transfer for connection to a field-device-internal interface provided for a display, comprising: an interface for connection to the field-device-internal interface; a radio module configured to wirelessly transmit a data packet on a low-power wide-area network, wherein the radio module is further configured to only transmit the data packet and not to receive any data packets; adapter electronics configured to limit an energy provided via the field-device-internal interface to a predefined value and to charge a stored energy source with the limited energy. The adapter electronics are further configured to monitor a state of charge of the stored energy source and, based on the state of charge, to provide the radio module with an energy originating from the stored energy source for transmitting the data packet.

The purpose of the present invention is to solve the new problem of appropriately protecting a control apparatus and a controller system including the control apparatus against a security event possible to occur. The support apparatus includes: a forming/editing part, providing a user interface for forming or editing a user program defining contents of the control arithmetic operation executed by the control apparatus; and an output part outputting the user program formed via the user interface provided by the forming/editing part. The forming/editing part provides a user interface receiving selection of a change instruction for changing a behavior of the security monitoring device carried out by executing the security protection process as an instruction constituting the user program.

Upon receipt of a signal indicating occurrence of anomalies, an information processor displays the nature of the anomalies. The information processor accepts for each anomaly, an input operation for assignment of a worker who is to handle an anomaly. Based on the assignment, the information processor notifies a terminal device of the worker of the nature of the anomaly to be handled by the worker. The terminal device displays contents of a remedy for the anomaly. The terminal device transmits progress information to the information processor. The information processor displays the progress information. The information processor further accepts an input operation for updating the assignment of a worker who is to handle the anomaly. Based on the assignment updated, the information processor notifies the terminal device of the worker of the nature of the anomaly to be handled by the worker.

A control system for use with a fire-fighting device includes a remote component having a touch sensitive screen configured to receive a user-requested parameter of fluid and to display a plurality of indicators associated with the fire-fighting device. The control system also includes a base component including a programmable logic controller having predefined logic stored thereon. The base component automatically controls operation of the pump based on the predefined logic and the user-requested parameter of fluid. The remote component receives signals from the base component and presents, via the touch sensitive screen, at least one of a first of the plurality of indicators indicative of a water volume associated with a first water source stored at a fire fighting device, and a second of the plurality of indicators indicative of a water pressure associated with a second water source remote from the fire-fighting device.

A method of operating an intelligent programmable logic controller (PLC) as part of a production process within an automation system includes the intelligent PLC receiving automation system data and a semantic context model comprising a plurality of ontologies providing formal specifications of conceptual entities associated with the automation system. The intelligent PLC creates one or more semantic annotations for the automation system data using the semantic context model. These semantic annotations are stored along with the automation system data in a non-volatile storage medium included in the intelligent PLC.

Techniques described herein may involve modification of playback based on the proximity of a user to a playback device. An example technique involves a device determining that a listener is within a given proximity of a first playback device and based on determining that the listener is within the given proximity of the first playback device, causing the first playback device to begin playback of first media and causing a second playback device to modify playback of second media.

In a normal operation of a roll stand (e.g. 4) of a roll train, working rolls (10) of the roll stand (4) are adjusted to a roll gap (s4) by adjusting a control element position (p4) of a control element (14) of the roll stand (4), such that the working rolls (10) roll the metal band (5). To determine the control element position (p4) to be adjusted, a calibration value (sC4) of the respective roll stand (4), further status parameters (P4) of the roll stand (4) and a target roll gap (s4*) are specified to a model (15) of the roll stand (4). The model (15) determines the control element position (p4) to be adjusted therefrom. In the calibration operation, a control element position (p4) is initially adjusted such that the metal band (5) passes through the roll stand (4) without being rolled. The control element position (p4) is varied such that the working rolls (10) roll the metal band (5). A thickness (d) of the metal band (5) is detected by a downstream thickness-measuring device (9). The thickness (d), further status parameters (P4) and the control element position (p4) are supplied to the model (15), which determines the calibration value (sC4) of the respective roll stand (4) therefrom. Subsequently, normal operation is resumed and the previously determined calibration value (sC4) is used to determine control element positions (p4) to be adjusted as the calibration value (sC4) of the respective roll stand (4).
