In a method for manufacturing memory modules MM, first a support board SB is populated with memory components MC. After the populating process, individual memory components MC are programmed via a bus system BS provided on the support board. After programming, the support board SB is separated into individual memory modules MM.

In a method for servicing a field device of process automation technology having at least two measurement channels, with the assistance of an external service unit, separate device descriptions are provided in the service unit for the measurement channels. The individual measurement channels can be invoked on the service unit via the corresponding device descriptions as logical units, so that, in servicing, the field device appears to the user as at least two logically independent field devices.

A measurement transmitter for a multisensor system for process automation technology, wherein the measurement transmitter, for processing in- and output signals, has a processor, which is connected with an interface, to which a sensor is connected for transmission of data via a transmission line. In communication between the processor and the interface, or the sensor and the interface, different transmission rates of data occur. In order to be able to connect to the measurement transmitter a plurality of sensors working with different principles of operation, and, in spite of the plurality of sensors, largely avoid errors in the data transmission, at least two sensors are present, wherein a function module is present in the interface for each sensor and the function module for each sensor is connected with such sensor via a dedicated transmission line.
摘要:
A method for operating a sensor in a multisensor system, especially in a field device in the form of a measuring device for process automation technology, wherein data output from the sensor are evaluated by the measuring device connected with the sensor and the measuring device supplies the sensor with energy. In order reliably to limit production of lost heat in a measuring device to a certain value and, in spite of this, to be able to connect a number of sensors with different energy requirements to a measuring device, before a startup of the sensor, it is checked whether, with startup of the sensor, a maximum consumption of electrical energy of the measuring device would be exceeded.
摘要:
An apparatus for servicing a field device from a remote terminal, wherein the field device has an onsite display/servicing capability and is connected to a fieldbus of process automation technology. The remote terminal and the field device communicate with one another via at least one defined transmission protocol. A web server is integrated in the field device, in a Plant Access Point or in the remote terminal; the web server provides all requested device information, which is the so called firmware, of the field device in the form of dynamically produced contents to the remote terminal. A communication driver specific to the applied transmission protocol and a browser are integrated in the remote terminal. The communication driver emulates the protocol of the onsite display/servicing capability of the field device on the remote terminal and the dynamically produced contents are displayed on a display of the remote terminal via the web browser, so that the onsite display/servicing capability at the field device and the display/servicing capability at the remote terminal are identical.

摘要:
A cable circuit for connecting a sensor module to a measurement transmitter. The cable circuit includes a contactless interface for signal transmission between the cable circuit and the sensor module, wherein the sensor module is galvanically isolated from the cable circuit, and wherein signal transmission between the cable circuit and the sensor module occurs on an optical, inductive or capacitive path. Additionally, the cable circuit includes a signal processing unit, as well as a cable interface for connecting a cable, which connects the cable circuit with the measurement transmitter. The signal processing unit is integrated into the signal path. The signal processing unit is embodied to receive, via the cable interface, signals from the measurement transmitter, to condition them and to transmit them via the contactless interface to the sensor module, and to receive, via the contactless interface, signals from the sensor module, to condition them and to transmit them via the cable interface to the measurement transmitter.
