Embodiment Construction
[0036] figure 1 A schematic representation of a preferred embodiment of the arrangement of the invention for servicing a field device 1 using a remote terminal 2 is shown. The field device 1 can be one of the above-mentioned field devices, independently connected to the bus system 4 . However, the field device 1 can also in particular be a control / evaluation unit to which a plurality of sensors / actuators 10 , 11 can be connected via corresponding channels. image 3 Such an example is shown in . A corresponding control / evaluation unit is manufactured and sold by the Endress+Hauser group under the trademark LIQUILINE, which previously lacked an embodiment of the invention, but which is suitable for the control and evaluation of a plurality of sensors / actuators 10 , 11 .
[0037] The remote terminal 2 may be a PC, a configuration / management system such as the configuration system FieldCare manufactured and sold by the assignee of the present application, or any handheld service...

The invention relates to an apparatus for operating a field device (1) via a remote terminal (2), wherein the field device (1) has an on-site display / controller (3) and is included in a fieldbus (4) for process automation, wherein the remote terminal (2) and the field device (1) communicate with one another using at least one defined transmission protocol, wherein a web server (5) is integrated in the field device (1), in a plant access point or in the remote terminal (2), and provides the respectively called-up appliance information, the so-called firmware, of the field device (1) in the form of dynamically produced contents (20) to the remote terminal (2), wherein a communication driver (6), which is matched to the transmission protocol being used, and a browser (7) are integrated in the remote terminal (2), wherein the communication driver (6); emulates the protocol of the on-site display / controller (3) of the field device (1) on the remote terminal (2), and wherein the dynamically produced contents (20) are displayed via the web browser (7) on a display (15) on the remote terminal (2), such that the on-site display / controller (3) on the field device (1) and the display / controller on the remote terminal (2) are identical.
Description
technical field [0001] The invention relates to an arrangement for servicing field devices from a remote terminal. The term "service field device" means configuration and parametering of a field device, but also includes diagnostics for early detection of defects in one or more field devices or in a process. Besides remote servicing of field devices from remote terminals, any kind of information transmission is also understood under the term "service". What is concerned in this context is the transfer of the parameterization of the field device from the field device to the remote terminal and the playback of the parameterization of the field device via the remote terminal to the field device. Like the parameterization of field devices, the production of printouts for printing with a printer is also understood to be "service". Generally, a remote terminal is understood to be, for example, a PC, a configuration / management system, which may be a configuration tool FieldCare man...
