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.

主权项：1. A system for servicing a field device from a remote terminal in an automation process, comprising: said field device for registering and/or influencing a process variable and said remote terminal, wherein said remote terminal and said field device communicate with one another via a bus system of process automation technology using a transmission protocol, the field device has an onsite display and servicing capability and is linked to said bus system; the remote terminal has a display and servicing capability, and has at least a communication driver specific to said transmission protocol, and a browser, said communication driver and said browser being integrated in the remote terminal; a JavaScript web application is loaded in the communication driver from the field device via the bus system; a web server is integrated in the field device, the web server provides all requested device information of the field device in the form of dynamically produced contents to the remote terminal via JavaScript Object Notation (JSON) so that the dynamically produced contents are displayed on the display of the remote terminal via the browser and on the onsite display of the field device, and the onsite display and servicing capability on the field device and the display and servicing capability on the remote terminal are identical at any time.
