Abstract

The invention relates to a field device (10), in particular a protective device, having a microprocessor arrangement (20) which executes a program module (PM), which defines the device function, during operation of the field device. The invention provides for the field device to have a protection device (40) which is configured in such a manner that it checks whether a function description block (FB), which has been input and describes a desired device function, describes an enabled device function and, in the case of a device function which has not been enabled, blocks execution of said function and, in the case of a device function which has been enabled, enables execution of said function.

Description

technical field [0001] The invention relates to a field device, in particular for use in energy technology devices such as power supply devices, having a microprocessor device which executes program modules which are dependent on the function of the device during operation of the field device. Background technique [0002] Such field devices are formed, for example, by protective devices SIPROTEC 7SA511 and 7SA513 from the company SIEMENS. The protective device is designed with a microprocessor device, which executes program modules that determine device functions during operation of the field device. [0003] Field devices in energy technology systems today perform many functions in protection and control technology. The performance and functionality of devices continues to improve. From the point of view of the field device manufacturer, there are more and more problems in providing suitable devices for each customer's expectations: Naturally, all the functions expected ...
