Definitions
- the invention relates to an input unit for a field device according to the preamble of claim 1.
- Field devices are e.g. used in process automation technology. They serve e.g. for registering, recording and / or influencing process variables. Examples of such field devices are level measuring devices, recording devices, e.g. paperless recorders, mass flow meters, pressure and temperature measuring devices, pH redox potential measuring devices, conductivity measuring devices etc., which as sensors record the corresponding process variables level, flow, pressure, temperature, pH value or conductivity value.
- level measuring devices e.g. paperless recorders, mass flow meters, pressure and temperature measuring devices, pH redox potential measuring devices, conductivity measuring devices etc., which as sensors record the corresponding process variables level, flow, pressure, temperature, pH value or conductivity value.
- Electrode cleaning systems, calibration systems and samplers are particularly worth mentioning here.
- Input / output input units so-called remote I / Os, are also referred to as field devices.
- Actuators are used to influence process variables.
- Endress + Hauser® manufactures and sells a large number of such field devices.
- Field devices in modern production systems are often connected to higher-level units via a fieldbus system (e.g. Profibus®, Foundation Fieldbus, HART etc.).
- a fieldbus system e.g. Profibus®, Foundation Fieldbus, HART etc.
- the sensors deliver the measured values that correspond to the current values of the recorded process variables. These measured values are sent to a registration device and / or to a control unit, e.g. B. a PLC (programmable logic controller), forwarded and recorded and / or evaluated there.
- a control unit e.g. B. a PLC (programmable logic controller)
- the process is controlled by such control units, where the measured values of the various field devices are evaluated and control signals for the corresponding actuators are generated on the basis of the evaluation.
- Fieldbus systems are also generally referred to as process control systems.
- An electronic signature or a signature by hand is to ensure that it is always traceable who has signed which documents and who has made which changes to field devices or control systems.
- the object of the invention is to provide an input unit for a field device, which enables simple and secure identification of a user, which in particular permits validation of systems or system components in accordance with official regulations.
- an input unit for a field device has a detection unit for an electronic identifier of a user, which allows a unique identification of a user and which thus corresponds to the new validation requests for plant / plant parts.
- the electronic identifier can be e.g. B. is the signature of a user.
- the signature is entered via a display (LCD display) provided on the input unit.
- LCD display LCD display
- electronic documents shown on the display can be handwritten by the user by entries on the display and / or can be commented on by hand.
- comments on the electronic documents will be stored unchangeably and / or provided with the time of entry.
- the signature is transmitted to the recording unit on a portable transmission unit.
- the signature can be used to sign electronic documents that are shown on the display of the input unit.
- the input unit advantageously meets the validation requirements FDA 21CFR PART 11.
- the input unit EE is preferably with a communication network
- FIG. 1 process control system in a schematic representation
- Fig. 2 input unit according to the invention for a field device in a schematic representation.
- the data bus D1 works e.g. B. after the HSE (high speed ethernet) Standard of the Foundation® Fieldbus.
- the data bus D1 is connected to a fieldbus segment SM1 via a gateway G1, which is also referred to as a linking device.
- the fieldbus segment SM1 consists of several field devices F1, F2, F3, F4, and an input unit EE, which are connected to one another via a fieldbus FB.
- the fieldbus works e.g. B. according to the Foundation Fieldbus standard. However, the invention is not tied to this special fieldbus system.
- the input unit EE for the field device is shown in more detail in FIG. 2.
- the input unit EE can e.g. act as an integral part of the field device.
- a sensor is shown as an example.
- the input unit EE has a microcontroller ⁇ C, which is connected via an analog-digital converter A D to a sensor MA, which is used to record a process variable (e.g. temperature, pressure, flow).
- a display / operating unit AB which is also connected to the microcontroller ⁇ C, is used to operate the field device and to display various information.
- the usual RAM and an EPROM memory serve as memory for programs and parameters.
- the microcontroller ⁇ C is connected to the fieldbus FB via a fieldbus interface FBS. Via the fieldbus FB e.g.
- the display operating unit AB has a display D and a plurality of switches S.
- the display D is designed as a so-called LCD touch screen and serves as a registration unit EF for the electronic signature.
- a user can identify himself on site at the input unit EE using his own signature. Here he writes his name (signature) on the display D using a corresponding pen. The user's signature is thus available in electronic form.
- electronic documents such.
- B. calibration reports, test reports or data recorded by a recording device can be displayed, which can be signed on site by a user.
- the electronic signature can be saved together with the corresponding documents.
- the user can comment on documents shown, for example by entering handwritten notes or marking selected areas, for example by arrows or circles. Depending on requirements, these entries can be saved unchangeably and / or the time of the entry can be provided. The entry can also be stored in such a way that it can no longer be deleted.
- the user's signature can also be used for access control for field devices.
- the name string is also saved in the field device F1
- Transfer communication connection e.g. radio WiFi, Ethernet, infrared
- Control unit stored names compared.
- the user no longer has to enter his name by hand on the display D, but instead transmits his signature to a corresponding recording unit using a portable transmission unit in which his signature is stored electronically.
- the display D does not have to be elaborately designed as a touch screen.
- So-called smart labels or radio tags which are also referred to as electronic labels, are particularly suitable for such a transmission unit.
- These labels are transponders that are queried via a radio signal from a distance of approx. 2 m and decode this signal accordingly. The energy required for signal processing is also obtained from this radio signal.
- the label also sends out its reply message as a radio signal.
