A measuring system having at least one field device with at least one display apparatus, wherein the display apparatus is embodied for displaying data, information and diagnostic reports of the field device, wherein the field device is supplied with voltage via a voltage input. A monitoring system is provided, which monitors the voltage at the voltage input and recognizes a voltage reduction, and the field device is embodied to execute a service program, which performs steps to shut down the field device in the case of a detected voltage reduction, characterized in that the service program is embodied, in the case of a detected voltage reduction, to show on the display apparatus a diagnostic report, which describes the state of the field device. The invention relates further to a method for operating the measuring system.

Measuring system having at least one field device with at least one display apparatus as well as method for operating same

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.
