Definitions

  • the invention relates to a method for transmitting parameter data when uploading and / or downloading parameter settings between filling devices and / or a guide parts according to the preamble of claim 1.
  • field devices are used in automation technology to detect and / or influence process variables.
  • Examples of such field devices for the detection of process variables are level gauges, mass flow meters, pressure gauges, temperature meters, etc., which record the corresponding process variables such as level, mass flow, pressure or temperature.
  • Examples of field devices for influencing process variables are so-called actuators, e.g. as valves control the flow of a liquid in a pipe section or as pumps the level of a medium in a container.
  • the field devices are connected via corresponding communication links, usually via a data bus, to a process control center, which controls the entire process sequence or allows direct access to the operating, parametric or configuration to the individual field devices.
  • a process control center which controls the entire process sequence or allows direct access to the operating, parametric or configuration to the individual field devices.
  • settings for example, parameters
  • settings on the field device can be changed or special diagnostic functions called up.
  • temporary access e.g. via a portable handheld device, portable computer or a mobile phone possible.
  • the process control center In order to enable the operation of various field devices from the process control center, the process control center must be familiar with the functionality of the field device.
  • the functionality of a Feideries is usually by means of a description of the device. Special standardized device description languages are available for this purpose; Examples are CAN - EDS (Control Aria Network - Electronic Data Sheet), Hart - DDL (Hard Device Description Language), FF - DDL (Fieidbus Foundation - Device Description Language), Profibus - GSD (Profibus - Device Master Data), Profibus - EDD (Profibus - Electronic Device Description).
  • the operation of the feeder is usually via a graphical user interface, which facilitates commissioning, maintenance, data backup, troubleshooting and device documentation.
  • the data transmission between the feeder and the process control center is wired or wireless according to one of the well-known international standards for fieldbuses, e.g. Hart, Foundation F ⁇ eldbus, Profibus, CAN etc or for remotely located parts via public communication networks.
  • the object of the invention is therefore to provide a method for a more efficient transmission of parameter data in a distributed process automation system.
  • the main idea of the invention is that the current parameter data are compared with stored standard parameter data and in the case of various types the assigned modification information I is set to "true.” Only such parameter data are transmitted during the transmission from the fattening device to the control center or vice versa in which a deviation from the standard parameter data is displayed by the modification information I.
  • the process data comprise information about the operating states of the field devices and / or information about the process variables that are detected by the field devices and / or identification data of the respective feeder Term field device are also understood actuators to influence the process variables.
  • a more efficient transmission of the parameter data is achieved in a further development of the invention in that, prior to the downloading of parameter data from the conducting parts into the field device, the standard parameter data are loaded in the field device by a reset process of the field device.
  • An additional reduction of the process data to be transmitted is advantageously achieved by monitoring the status information of the parameter data transmitted in previous transmissions and automatically starting a transmission of the changed parameter data upon a renewed change of this monitored status information.
  • Specifications for the evaluation of process data and / or implementation the transmission of the reduced process data can be influenced by a user.
  • the predetermined conditions for triggering a data transmission as defaults include, for example, a certain period of time and / or a predetermined time.
  • the specifications may also include the occurrence of certain events, such as the achievement and / or exceeding of predetermined thresholds or alarm criteria. This reduces the number of data transfers and thus the amount of data.
  • all presettings which can be influenced by the user for a field device are stored in an individual device description file belonging to the field device.
  • the device description file also describes the functionality of the associated field device and also includes, for example, information about the process variables that can be determined and / or influenced by the field device and which are otherwise transmitted as static data from the feeder to the process control center.
  • the field device is assigned its individual device description file.
  • the Internet is used as a communication platform between the Fefd réelle and the process control center.
  • the data transmission between the feeder and the Vietnameseieitstelte is unidirectional, wherein when data from the process control center must be transmitted to the field device, a bidirectional communication is performed.
  • This measure is particularly important for locations, for example, in remote large deposits where the field device normally shut down to save energy and only in the presence of predetermined conditions, for example, at the end of a certain period of time or at certain times activated.
  • the field device determines the process data that is subsequently evaluated, stored and transmitted to the process control center. Subsequently, the field device remains activated for a predetermined period of time and switches off again after the expiry of the time interval.
  • the process control center After receiving the process data, the process control center checks whether new data, for example changed conditions for initiating data transmission, has to be transmitted to the field device. If no such new data is transmitted from the process control center to the field device, the field device switches off again after the predetermined period of time.
  • a control / evaluation unit For carrying out the method according to the invention, a control / evaluation unit is provided, wherein the control / evaluation unit reads out the modification information I of the parameter data and stores its status in a memory unit, wherein the memory unit can be part of the control / evaluation unit, and wherein the control unit / Evaluation unit from the changes in the modification information I forms the parameter data to be transmitted and transmits by means of appropriate communication facilities to the process control center.
  • corresponding control and display units provided, which are arranged for example in the process control center.

  • a control and evaluation unit 16 is integrated, the control of the automation process, the evaluation of the measured values or control values of individual field devices 5 and / or analysis and diagnosis of the information I and the measured value Mx of the field devices 5 performs.
