Definitions
- the invention relates to a programmable field device.
- Field devices are widely used in process control and automation technology to process variables such as Mass flow, level, pressure, temperature, etc., to be recorded by means of appropriate measurement sensors and converted into an analog or digital measurement signal representing the value of the process variable.
- Such field devices are usually connected via a data transmission system to a central process control unit to which the measurement signals e.g. can be transmitted via a 2-wire current loop and / or via a digital data bus.
- a central process control unit to which the measurement signals e.g. can be transmitted via a 2-wire current loop and / or via a digital data bus.
- the transmitted measurement signals are further processed in the central process control unit and, for example, as corresponding measurement results visualized on monitors and / or in control signals for process actuators, e.g. Solenoid valves, electric motors etc., converted.
- process actuators e.g. Solenoid valves, electric motors etc.
- the software is saved in a permanent memory, e.g. a PROM or a non-volatile memory, e.g. an EEPROM, programmed by the microcomputer and, if necessary, for the operation of the field device in a volatile memory, e.g. a RAM, loaded.
- a permanent memory e.g. a PROM or a non-volatile memory, e.g. an EEPROM, programmed by the microcomputer and, if necessary, for the operation of the field device in a volatile memory, e.g. a RAM, loaded.
- the processes observed by means of the field devices are subject to constant modification, both in terms of the construction of the systems and in terms of the time sequences of individual process steps.
- the field devices must be adapted to the changing process conditions and further developed. This extends on the one hand to the transducers, but on the other hand also to the implemented functions, such as the control of the measured value pickup, the evaluation of the measurement signals or the presentation of the measurement results as well as the communication with the data transmission system.
- Some of the field devices are supplied with voltage via 2-wire lines (4-20 mA, Hart, or Profibus-PA).
- the 2-wire line is also used for data transmission from the field device to the central process control unit.
- 2-wire line systems are generally limited with regard to the voltage and power supply, this is especially true in potentially explosive areas. Because the power consumption of the field devices, which are supplied via a 2-wire line, is severely limited, such devices are also referred to as low-power devices. Energy-intensive applications can therefore only run slowly.
- the object of the invention is to provide a field device which enables faster work in service cases.
- a programmable field device which has a sensor, evaluation electronics and a communication unit with a connection unit, an additional voltage supply unit being provided which can be connected to the connection unit.
- the voltage supply unit advantageously has a battery.
- the voltage supply unit has solar cells.
- the voltage supply unit can be connected to a service socket arranged on the field device.
- the voltage supply unit is designed to be explosion-proof.
- the essential idea of the invention is that sufficient electrical energy can be supplied to the field device by an additional voltage supply unit, so that certain applications (energy-intensive storage or
- Memory query can be carried out more quickly.
- FIG. 1 shows a schematic illustration of a field device with a voltage supply unit according to a first
- FIG. 2 shows a schematic representation of a field device with a voltage supply unit according to a second embodiment.
- the field device 1 shows a field device 1, which is connected to a sensor 2.
- the field device essentially consists of an electronics unit 4, which is a microcomputer and a
- the electronics unit 4 evaluates the sensor signal of the sensor 2 and outputs a measurement signal representing the measurement value to the communication unit 5.
- the communication unit 5 transmits the measurement signal to a process control unit 20, where the measurement value of the sensor 2 is evaluated and, if necessary Tax measures are taken that regulate the process flow.
- the process control unit 20 controls actuators which are not shown in detail.
- the electronics unit 4 is also connected to a display unit 3, which is used, for example, to display the measured value of the sensor 2.
- the communication unit 5 is connected to a connection unit 7 which has a 2-wire connection 8 and a service socket 9.
- the 2-wire connection 8 is connected to a 2-wire line 22, which leads to a process control unit 20.
- 2-wire line 22 is used for communication between field device 1 and process control unit 20 and the voltage supply for field device 1.
- a service socket 9 is connected in parallel with 2-wire connection 8.
- a voltage supply unit 10 is detachably connected to the service socket 9.
- the voltage supply unit 10 has two 12 V batteries Batl and Bat2 connected in series.
- additional diodes ZD1, ZD2 and ZD3 are provided, which are arranged between the two battery connecting lines L1 and L2.
- the communication unit 10 consists of a plastic housing and is completely encapsulated.
- connection unit 7 In a second exemplary embodiment, the 2-wire connection 8 and the service socket 9 in the connection unit 7 are not connected in parallel but separately.
- two diodes ZD4 and ZD5 prevent the current backflow from field device 1 to the voltage supply unit 10.
- the voltage supply unit 10 is connected to the field device 1 via the service socket 9.
- the data can e.g. B. between the field device 1 and a handheld device, a portable PC or other communication devices using a 2-wire
- Envelopes of this type consist of a large number of data, the reading of which is energy-intensive.
- the field device can also be parameterized externally via the communication device. In this case, too, it may be necessary to transmit a large amount of data.
- the supply unit 10 provides the field device with sufficient electrical power so that even energy-intensive applications can be carried out quickly.
- envelopes can be read in faster from field device 1.
