Definitions

  • the invention relates to a method for providing information about an error in an automation technology system, the system having a large number of field devices which are installed at distributed installation locations, with at least one mobile control unit being used in the system.
  • Field devices that are used in industrial plants are already known from the prior art. Field devices are often used in process automation technology as well as in production automation technology. In principle, all devices that are used close to the process and that supply or process process-relevant information are referred to as field devices. Thus, field devices are used to record and/or influence process variables. Measuring devices or sensors are used to record process variables. These are used, for example, for pressure and temperature measurement, conductivity measurement, flow measurement, pH measurement, level measurement, etc. and record the corresponding process variables pressure, temperature, conductivity, pH value, level, flow rate, etc. Actuators are used to influence process variables. These are, for example, pumps or valves that can influence the flow of a liquid in a pipe or the fill level in a container. In addition to the measuring devices and actuators mentioned above, field devices also include remote I/Os, wireless adapters or devices in general that are arranged at the field level.
  • field devices are usually connected to higher-level units via communication networks such as fieldbuses (Profibus®, Foundation® Fieldbus, HART®, etc.).
  • the superordinate units are control systems or control units, such as a PLC (programmable logic controller).
  • the higher-level units are used, among other things, for process control, process visualization, process monitoring and for commissioning the field devices.
  • the measured values recorded by the field devices, in particular by sensors, are transmitted via the respective bus system to one (or optionally several) higher-level unit(s).
  • data transmission from the higher-level unit via the bus system to the field devices is also required, in particular for configuring and parameterizing field devices and for controlling actuators.
  • operating programs are required to operate the field devices, which either run independently on the higher-level units (Endress+Hauser FieldCare, Pactware, AMS Fisher-Rosemount, PDM Siemens) or in control system applications (Siemens PCS7, ABB Symphony, Emerson Delta V) are integrated. It is also possible to run the operating programs on a mobile operating device in order to use it to operate the field devices. Operation means, in particular, parameterizing, configuring and reading out data from a field device.
  • Such field devices are usually distributed over a very wide area in larger systems, in particular in production systems.
  • these field devices must be identified and localized as quickly as possible in order to eliminate the error on site or to be able to carry out maintenance.
  • the error case is typically reported today to the control center or the control room of the system. This results in the orders that an operator, for example a service employee, has to complete in the system. The operator must then go to the site with the information needed to correct the error in order to correct the error.
  • US 2012/0040698 A1 describes an operating unit which has a GPS module.
  • a service technician is guided to the various components by displaying a map of a process automation system on the display of the operating unit, which visualizes the current position of the service technician and the local positions of components of the system.
  • DE 10 2012 108 99 A1 describes several variants by means of which field devices can be localized in a process automation system.
  • a service technician sends the identification information of a field device to a database. This then tells the service technician where in the system the field device is located, so that he can be guided to the installation site of the field device with the help of his operating unit.
  • the service technician uses his control unit to record his current location.
  • the database then transmits to the service technician location information on those field devices of the system which are located within a defined radius based on the location of the service technician.
  • the field devices to be searched for must be selected manually. To do this, the service technician must know which field devices are currently faulty. Spontaneously occurring errors in field devices are not known to the service technician while he is in the plant.
  • the invention is therefore based on the object of servicing faulty field devices in an automation technology system in an efficient and time-saving manner.
  • the object is achieved by a method according to claim 1 and a mobile control unit according to claim 11.
  • this is used to provide information about an error in an automation technology system, wherein the system has a large number of field devices which are installed at distributed installation locations, wherein at least one mobile control unit is used in the system, comprising:
  • the mobile control unit In the event that the distance is less than a predetermined distance, generating and transmitting maintenance information to the mobile control unit, the maintenance information having at least one identification of the field device.
  • the method according to the invention makes it possible to specifically inform an operator in an automation technology system, for example a service technician, about a fault in a field device in the system.
  • an automation technology system for example a service technician
  • two conditions must be met:
  • An operator's control unit must be in the immediate vicinity or within a given distance from the installation site of the field device.
  • the maintenance information is immediately made known to the operator via his operating unit, for example by means of a push notification.
  • Methods known from the prior art always require a field device to be selected from a list, as a result of which the operator has to independently search for errors, whereas thanks to the present invention he is informed automatically.
  • the current location of the field devices is continuously updated until one of the control units is within the predetermined distance and the maintenance notification can be transmitted to it.
  • the conventional way of notifying an operator can be used.
  • Another advantage is that the infrastructure of the plant does not have to be changed, since the conventional communication of the field devices remains unchanged. For certain configurations of the method, however, it may be necessary to update the firmware or the software of the field device and/or the operating unit.
  • the device status is designed in particular according to the Namur recommendation NE107.
  • a cloud-based platform in which the location of the installation location of each of the field devices and the device status of each of the field devices is stored, with the mobile control unit continuously transmitting its current location to the cloud-based platform, and where the cloud-based platform performs the steps of determining the distance, and generating and transmitting the maintenance information.
  • a "cloud-based platform” is a server that can be contacted by an operator, the field devices and/or the mobile control unit via the Internet or local network, on which one or more applications are running, which display, process and manage data from the assets of a plant allows.
  • the field devices have a position determination module, in particular a GPS module, visual light communication module, Bluetooth beacons module, etc., and independently determine and transmit the location of their installation location submit to the cloud-based platform.
  • a position determination module in particular a GPS module, visual light communication module, Bluetooth beacons module, etc.
  • the location of the installation site of the field devices is entered manually into the cloud-based platform.
  • field devices are attached to fixed installation positions, which usually only change when the measuring point is changed. It is therefore sufficient if a field device communicates its spatial position of the installation site only when it is put into operation or when the installation site is changed.
  • the field devices determine their device status independently and transmit it to the cloud-based platform.
  • the field devices have specific diagnostic tools for this purpose.
  • Certain field devices from the companies Endress+Hauser have, for example, the "Heartbeat" diagnostic tool, which can be used to determine the device status of a field device or its components.
  • the field devices transmit their data to the cloud-based platform, with the platform determining the respective device status on the basis of the transmitted data.
  • An edge device for example, is provided for the transmission of the data, which is connected, for example, directly or via a gateway to a fieldbus of the field devices and which data of the field devices eavesdrops on the data traffic of the fieldbus (or the gateway eavesdrops on the data and transmits it to the edge device) or actively polls data from the field devices.
  • the field device itself is in communication with the cloud-based platform via a LAN/WAN network or the Internet and transmits its data independently.
  • the data can be measured values, diagnostic values, parameter data, etc.
  • the cloud-based platform determines the respective device status based on a defined set of rules or with the help of an AI algorithm.
  • the field devices emit radio signals at regular intervals, with the mobile control unit receiving the radio signals and using parameters of the radio signals, in particular the signal strength, determining the distance to the respective field devices.
  • the advantage here is that the distance can be determined more precisely. If the mobile control unit is located under a roof, for example, it is not possible to determine its location using GPS. Such a determination of the distance between two devices is made possible using modern wireless standards, such as Bluetooth LE.
  • no parameter of the radio signals is determined.
  • the distance is considered sufficiently close if the control unit can receive a radio signal from the field device.
  • the mobile control unit transmits information to the cloud-based platform when the distance is less than the predetermined distance, and the cloud-based platform then transmits the maintenance information to the mobile control unit.
  • the field device transmits the maintenance information to the mobile control unit. Only if the control unit is within the predetermined distance is located, the maintenance information can be transmitted.
  • the advantage here is that no communication connection needs to be established between the operating unit and the cloud-based platform.
