Embodiment Construction

[0042] figure 1 An example of an embodiment of the method of the invention based on factory automation technology is shown. Connected to the data bus D1 are a number of workstations PC WS1, WS2, usually at factory level. These workstation PCs are used as superordinate units (control systems or control units), inter alia, for process visualization, process monitoring and for management, such as for servicing and monitoring field devices. The data bus D1 works for example according to the Profibus DP standard or according to the HSE (High Speed ​​Ethernet) standard of FOUNDATION Fieldbus. The data bus D1 is connected with the field bus segment SM1 via a gateway G1, a field controller or a segment coupler, which can be referred to as a link device. The field bus segment SM1 consists of a plurality of field devices F1 , F2 , F3 , F4 connected to one another via a bus FB. The field devices F1, F2, F3, F4 can be sensors or actuators. The Fieldbus FB works according to one of the...

Abstract

The present disclosure includes a method and a system for remote-controlled servicing of a field device of process automation, including establishing a communication connection between a service unit(SU) and the field device (F1, F2, F3, F4) via a first network (N1), sending via a second network (N2) an access request from a computer unit (CU) to an application program (AP) executed on the service unit (SU), wherein the application program (AP) serves for servicing the field device (F1, F2, F3, F4), approving the access request via the application program (AP), and establishing access of thecomputer unit (CU) to the application program (AP) via the second network (N2) upon approval of the access request, wherein, after established access, the servicing of the field device (F1, F2, F3, F4) occurs from the computer unit (CU).

Description

technical field [0001] The invention relates to a method for remote control servicing of field devices for process automation. Furthermore, the invention relates to a system for carrying out the method of the invention. Background technique [0002] The use of field devices in industrial plants is well known in the art. In process automation technology as in manufacturing automation technology, field devices are often used. In principle, so-called field devices are all devices that are used in the vicinity of the process and transmit or process process-related information. Therefore, field devices are used to register and / or influence process variables. The process variables serving to register are measuring devices, or sensors. These are used, for example, for pressure and temperature measurement, conductivity measurement, flow measurement, pH measurement, fill level measurement, etc., and to register the corresponding process variables, pressure, temperature, conductiv...
