摘要:
A method for operating a field device via a fieldbus system for fieldbus communication with at least one additional field device. A web server a web browser, and a web server communication interface, via which the web browser, and a web server communication is performable. The method includes the steps executed by the field device as follows: receiving a web browser query via the web browser, web server, communication interface concerning at least also information of at least one additional field device; retrieving the queried information from the respective, at least one additional field device via the fieldbus communication connection; incorporating the information obtained from the at least one additional field device into a web page; and providing the web page via the web browser, web server, communication interface.
摘要:
In a method for parametering a field device of process automation technology, wherein the field device is connected via a bus system with a control unit, parameter values are packaged in telegrams of cyclic services and transmitted to the field device whose parameter values are to be changed. No acyclic services are required for changing parameter values.
摘要:
A method for operating an automation technology field device connected via a bus system with a superordinated unit and having an identifier identifying the type of the field device, at least one alternative identifier AKF1, which identifies a similar type of field device, is stored, in addition to an identifier KF1, in the field device F1. This alternative identifier AKF1 is transmitted, on query, to the superordinated unit PLC, when the superordinated unit fails to accept as valid the identifier KF1 transmitted in prior queries. In this way, a replacement of a field device is possible simply and quickly.

摘要:
A field device of process automation technology containing a plurality of parameters, with which are associated device-internal parameter addresses. The field device is connectable to a fieldbus having a fieldbus-specific parameter addressing system. In such case, the device-internal parameter addresses of the plurality of parameters are determinable by application of a generic mathematical function to belonging fieldbus-specific parameter addresses formed according to the fieldbus-specific parameter addressing system.

摘要:
A method for providing an operating menu (OM) for a field device (FD) of process automation technology, wherein the operating menu (OM) is displayed on a display unit of a servicing device (SD) remote from the field device (FD) by means of a web browser (WB). Settings of the field device (FD) are editable via the operating menu (OM); wherein a number of different operating menus (OM) are available by means of a web server (WS), especially a web server (WS) integrated in the field device (FD); and wherein one of the available operating menus (OM) is selected, especially by a user, via the web browser (WB).
