METHOD FOR REMOTELY OPERATING A FIELD DEVICE OF PROCESS AUTOMATION TECHNOLOGY

摘要

The invention relates to a method for remotely operating a field device (F1...F4) using a client application (CA), which runs on a hand-held terminal (HB) and an operating program, which runs on a computer (WS1, WS2) and comprises a frame application (FDT frame), that operates field devices in a conventional manner using corresponding device drivers according to the (DTM-Fl, DTM-F2) client-server principle. A service driver for the (DTM-SD) frame application is provided, which permits communication between the operating program and the service interface (W5). Communication between the client application and the operating program takes place between a corresponding service interface. This permits a field device to be operated in a simple manner by a hand-held terminal.
