Definitions

  • Field device for process automation for acquisition and / or
  • the invention relates to a field device for process automation for recording and / or influencing a process variable with at least two communication interfaces.
  • Field devices are often used in automation technology to record and / or influence process variables. Examples of such field devices are fill level measuring devices, mass flow meters, pressure meters, temperature meters, etc., which record the corresponding process variable fill level, mass flow, pressure or temperature. These field devices are also referred to as sensors. In addition to sensors, there are also field devices, so-called actuators, which, for. B. regulate the flow of a liquid in a pipe section as valves or pumps that serve to fill containers. Actuators influence the respective process variable flow, level, temperature etc.
  • the fieldbus is used for digital data communication with control units or control systems or other field devices.
  • Programmable logic controllers that control the process flow are often used as control units. In these control units, the measured values of the various sensors are evaluated or monitored and the actuators are controlled accordingly.
  • the fieldbuses are often still connected to higher-level communication networks via these controls or gateways, which are used for data communication with control systems (Siemens Simatic S7, Fisher Rosemount Delta V, ABB Symphony) and possibly also with business systems (e.g. SAP R3).
  • the process flow is monitored and visualized in a control system.
  • the control system also serves to engineer the various field devices. Often, not only one bus is used at the field level, but different buses with different bus protocols. One reason for this is that each fieldbus now allows a limited cable length and thus field devices that are relatively far apart cannot be connected to each other via every fieldbus. Another reason for using different fieldbuses is their use in potentially explosive areas. Not every fieldbus can be used in Ex areas. Another reason for different buses is the data rate, which is relatively low for field buses.
  • the data communication on the different buses takes place according to different protocols. Therefore gateways are necessary as connections between the buses. A protocol conversion to the protocols used in the respective buses takes place in the gateways.
  • a gateway When using two different buses, a gateway is therefore always required as a connection. Since the gateway is a separate device that usually has to be installed in a cabinet, a complex installation is necessary.
  • the object of the invention is to provide a field device for process automation for recording and / or influencing a process variable with two communication interfaces, which does not have the disadvantages mentioned above and which is particularly easy to install and inexpensive.
  • the essential idea of the invention is to provide two communication interfaces for two different buses in a field device, the protocol conversion for data to be transmitted between the two buses taking place in the field device itself. An additional gateway is therefore no longer necessary.
  • Fig. 1 shows a schematic representation of an automation system with two field buses that are connected via a gateway.
  • Fig. 2 shows a schematic representation of an automation system with two field buses without a gateway connection.
  • Fig. 3 shows a schematic representation of a field device with two communication interfaces.
  • FIG. 1 shows a schematic representation of a conventional automation system in which two buses, a field bus FB1 and a further data bus FB2 are connected to one another via a gateway G.
  • the fieldbus FB1 is connected to three field devices F1, F2 and F3.
  • Field devices F essentially consist of a transmitter T1, T2, T3 and a sensor element S1, S2, S3.
  • the sensor element S3 is not arranged directly on the transmitter T3 but at the end of a longer connecting line L3.
  • FIG. 2 shows a schematic representation of an automation system corresponding to FIG. 1 with two buses FB1 and FB2 but without a separate one Gateway.
  • the field device F1 ' is directly connected to the fieldbus FB1 and the bus FB2.
  • Fig. 3 shows a schematic representation of a field device here F1 ' with two communication interfaces K1 and K2, which are used for connection to the respective buses FB1 and FB2.
  • the two communication interfaces K1 and K2 are each connected to a microcontroller MC.
  • the sensor element S1 is used to record a process variable (e.g. pressure, temperature, level or flow). It is connected to the microcontroller MC via an A / D converter A / D.
  • a memory S (program memory) and an EEPROM for non-volatile data (parameters) are provided as memory elements of the field device F1 'and are likewise connected to the microcontroller MC.
  • a display D which is also connected to the microcontroller MC, serves to display and operate the field device F1 ' .
  • the field device is supplied with voltage via a separate power supply unit SV, which is fed either via a fieldbus or separately via a supply connection.
  • the bus FB2 is used to connect a field device (for example F1) to a programmable logic controller PLC.
  • a field device for example F1
  • a programmable logic controller PLC a field device
  • the following known standards are conceivable as a possible combination of the two buses FB1 and FB2: FB1: HART - FB2: Profibus DP, Profibus PA, Fieldbus Foundation H1, Fieldbus Foundation HSE, Ethernet, TCP / IP, GSM, Bluetooth FB1: Profibus PA- FB2: Profibus DP, Fieldbus Foundation H1, Fieldbus Foundation HSE FB1: Fieldbus Foundation H1 - FB2: Fieldbus Foundation HSE, Profibus DP
  • the functioning of the field device according to the invention is described in more detail below.
  • the field device F1 ' communicates in a known manner with the programmable logic controller PLC via the communication interface K2 and the fieldbus FB2.
  • the corresponding data in the respective protocol is sent to the field device F1 ' via the bus FB1.
  • the protocols are implemented accordingly in the field device F1 'and the data is transmitted on the bus FB1 to the respective field device F2 or F3.
  • the data communication between field device F2 or F3 and the programmable logic controller PLC takes place in the opposite way.
  • the essential idea of the invention is that the protocol conversion necessary when two buses are connected takes place in a field device.

Abstract

L'invention concerne un appareil de terrain (F1') pour l'automatisation de processus servant à enregistrer et/ou influencer une variable de processus, lequel appareil présente deux interfaces de communication K1 et K2. L'interface de communication K1 permet la liaison avec un premier bus de terrain et l'interface de communication K2 permet la liaison avec un deuxième bus de terrain. Une conversion de protocole pour les données transmises entre les deux bus de terrain FB1 et FB2 est réalisée dans cet appareil de terrain. Ainsi, une passerelle supplémentaire pour la liaison des deux bus de terrain n'est plus nécessaire.
