A method for providing static data and dynamic data of a service/display menu for a mobile device from a field device containing identification data and a total amount of static data and dynamic data. Upon query of the mobile device, dynamic data and/or static data are transmitted from the field device to the mobile device via a wireless interface. Static data required for an application for representation and/or changing of transmitted dynamic data are transmitted from the field device to the mobile device. These static data are stored in a memory in the mobile device. Further disclosed is a computer program for performing the method and an arrangement comprising a field device and a mobile device for performing the method.

Method for providing data for a mobile device from a field device, computer program and arrangement for executing same

A measuring arrangement, which includes: a sensor, wherein the sensor is embodied to produce a measurement signal correlated with a measured variable, a first interface, an evaluation circuit least one computer system and a memory associated with the computer system, as well as a third interface, especially a third interface embodied as a fieldbus interface, a first superordinated data processing system, with which the evaluation circuit is connected via the third interface, wherein in the memory associated with the computer system of the evaluation circuit a computer program executable by the computer system is stored, wherein the computer program serves for additional processing of the measurement signal as well as serving for transmission of the further processed measurement signal via the third interface to the first superordinated data processing system; and a second superordinated data processing system connected wirelessly, especially via a radio connection, with the evaluation circuit.

Measuring arrangement

A method for providing static data and dynamic data of a service/display menu for a mobile device from a field device. The field device contains identification data, and, associated therewith, a total amount of static data and dynamic data. Upon query of the mobile device, dynamic data and/or static data are transmitted with a data transmission rate from the field device to the mobile device via a wireless interface. Static data required for application, especially for representation, and/or changing of transmitted dynamic data are transmitted from the field device to the mobile device, when the static data corresponding to the identification data are not already present in the mobile device; wherein these static data make up only a portion of the total amount of static data in the field device, so that an application, especially a representation, and/or changing of the transmitted dynamic data by the mobile device is enabled with the portion of the static data; and wherein these static data are stored in a memory in the mobile device. A computer program for performing the method is disclosed, and an arrangement comprising a field device and a mobile device for performing the method.

A system for communication with a field device, comprising: an apparatus which includes a communication module and an adapter. The communication module includes a connection region and a communication area. The communication area includes at least one communication interface for communication for the field device. A first connecting structure is provided on the connection region, and a second connecting structure provided on an adapter, wherein the second connecting structure is embodied complementary to the first connecting. The adapter includes an interface, and the adapter is embodied passively A display/servicing device, wherein the interface is embodied for connection to the display/servicing device, wherein the display/servicing device is embodied as a portable mobile device, wherein the mobile device is embodied for single-use battery- or rechargeable battery operation, and wherein the first connecting, the second connecting structure and the interface are embodied as plug contacts.

Apparatus for transmitting and/or receiving measurement data of a field device with passive adapter interface

A method for unilaterally or mutually authenticating at least one first unit, especially a mobile device, on at least one second unit, especially a field device, within a plant, especially in the area of process automation technology, with a communication line, preferably a wireless communication line, in place between the first unit and the second unit, comprising the steps of: establishing a security policy, with the security policy including rules for granting access of the first unit on the basis of at least one unlock key, and information to check the unlock key for validity; providing the security policy to the second unit; generating an unlock key for the first unit and providing the unlock key at the first unit; transfer of the unlock key from the first unit to the second unit and verification of the unlock key by the second unit using the security policy and, if applicable, granting access. Furthermore, a computer program product executes the method and a machine-readable data carrier includes the computer program product.

Method for the authentication of at least one first unit on at least one second unit

A wireless dongle for use in the potentially explosive area for an automation field device to connect to an electrical interface of the field device, having a wireless circuit for sending and receiving wireless signals and a connector element. The wireless dongle can be detachably fitted to the electrical interface by means of the connector element. The connector element has several contact elements, wherein the contact elements are attached to a printed circuit board in the wireless dongle, that a first contact element is used to supply the wireless dongle with energy, that an energy buffer on the printed circuit board is provided which is downstream of the first contact element. The connector element has a second contact element which is used to transmit data between the field device and the wireless dongle, that in each case there is at least one limiting resistor is downstream of the first contact element and the second contact element, and that the resistors and the energy buffer of the wireless dongle are encapsulated by means of a potting compound.

Intrinsically safe wireless dongle for a field device

A method for operating a measuring device comprising the following steps: providing a first sample of the liquid; ascertaining an updated calibration function by means of a standard addition method, wherein the first sample is supplemented at least once with a standard solution, which has a known concentration of the measured ion; determining a measured value of concentration of the measured ion in the first sample; providing a second sample of the liquid; ascertaining a measured value of concentration of the measured ion in the second sample as a reference measured ion concentration (c) by means of a reference method; and determining a difference (c) between the apparent measured ion concentration (c) and the reference measured ion concentration (c) and deriving a correction value (c) therefrom for future measured values of concentration of the measured ion in the liquid, as ascertained with the measuring device.
