Abstract:
An apparatus and a method for gravimetrically metering pourable or flowable material to be weighed are provided. A container holds the material to be weighed and a weighing device detects the weight of the container. A first actuator fills the container located on the weighing device with the material to be weighed and a second actuator empties the container or places the empty container on the weighing device. Further, a control device for generating control signals for the actuators is provided. A signal filter with a variable filter characteristic filters the weighing signal delivered by the weighing device. A filter matching device, controlled by the control device, matches the filter characteristic as a function of the control signals to various predetermined filter characteristics.
Abstract:
A field device, which, as part of an automation system, carries out device-specific functions in the automation of the operational sequence of a system, detects and processes at least one measured variable from the system and has a communication interface for communication with the automation system. In order to make possible measurements signal filtering, the measured variable detected by the field device from the system is filtered in a signal filter, whose filter characteristic is variable and is matched to different predetermined filter characteristics as a function of event information from the operation sequence of the system obtained via the communication interface.
Abstract:
A process automation system in which process devices (1-6) execute predetermined functions as part of the process automation and exchange data (23, 24) relevant to functions and/or devices with the process automation system. Some but not all of the data (23, 24) are exchanged in encrypted form.
Abstract:
Calibration-required data arc displayed by an industrial visual display system, which can be configured using a predetermined configuring software and which has a standard interface for integrating additional applications. To this end, the calibration-required data are integrally protected and optionally encoded. The arc then transmitted to the visual display system and decoded therein by an application that is integrated via the standard interface, after which they are visually displayed in a form that is different from the presentation possibilities that can be configured by the configuring software.
