Definitions
- the invention relates to a method for controlling the power supply of several field devices.
- field devices are often used to measure process variables (sensors) or control variables (actuators) in the process.
- Field devices for flow, fill level, differential pressure, temperature determination etc. are generally known. To record the corresponding process variable, mass or volume flow, fill level, pressure, temperature etc., the field devices are arranged in close proximity to the relevant process component.
- the field devices deliver a measurement signal that corresponds to the measurement value of the detected process variables.
- This measurement signal is forwarded to a central control unit (e.g. a control room or process control system).
- a central control unit e.g. a control room or process control system.
- the entire process is controlled by the control unit, where the measurement signals from various field devices are evaluated and control signals for actuators which control the process flow are generated on the basis of the evaluation.
- An example of an actuator is a controllable valve that regulates the flow of a liquid or a gas in a pipe section.
- Programmable field devices usually use ASICs (application-specific integrated circuits) or SMDs (surface mounted devices). With programmable field devices, more and more "intelligence" is being shifted into the field to the actual place of use.
- ASICs application-specific integrated circuits
- SMDs surface mounted devices
- the corresponding control program of the field device is stored in a non-volatile memory in the field device and is executed in a microprocessor. Among other things, it controls the operation, measurement and control functions of the field device.
- the field devices are often supplied with power via the data bus line.
- the consumption value corresponds to the peak load in order to always supply the field device with sufficient electricity.
- the consumption value lies between the peak load and the base load.
- these field devices must have an energy store in order to be able to cover their energy requirements during the measuring times. If the energy storage is completely filled, the energy made available above the base load must be uselessly converted into heat.
- limit value Only a certain amount of electricity (limit value) can be made available via a data bus line. That is, the number of field devices connected to a data bus line is limited. The sum of the consumption values of the individual field devices must not exceed the limit. If as many field devices as possible are to be connected to a data bus line, the consumption values of the individual field devices must be as low as possible can be selected, which results in a low measurement rate of the individual field devices.
- Data bus line are connected and are supplied with power via the data bus line, the current consumption of each field device being adjustable, with the following
- the essential idea of the invention is to control the power supply of several field devices in accordance with the current utilization of the data bus line across field devices.
- the current consumption of the field devices can thus be adapted in accordance with the current power requirements of the individual field devices and the current utilization of the data bus line. As a result, the number of field devices connected to the data bus line can be increased (cost savings) or the measurement rate of the field devices can be increased.
- control signals can advantageously be sent by a process control system or by one of the field devices.
- control signals can be sent from successively authorized field devices.
- the invention also relates to a device for carrying out the method.
- Fig. 1 shows a schematic representation of a data bus system with several field devices
- FIG. 2 schematic representation of a field device.
- Fig. 1 is a data bus system DBS with several field devices and one
- Process control system PLS shown.
- the field devices are
- the process control system PLS is usually arranged in a control room from which the entire process control takes place centrally.
- Actuators A are "in the field" for the individual process components (tank,
- the sensors S1, S2 and S3 detect e.g. the process variable temperature T,
- the Actuators A1 and A2 are, for example, valve controls that control the flow of a
- the data communication between the process control system PLS, the sensors S and the actuators A takes place in a known manner according to an internationally standardized transmission technology (e.g. RS 485 or IEC 1158) using special protocols (e.g. PROFIBUS or FOUNDATION FIELDBUS, CAN-
- the sensor S1 is connected directly to the DBL data bus line.
- the connection is made by means of a T-coupler T, which is connected to a fieldbus interface FBS via a data line DL1.
- FBS fieldbus interface which is often also referred to as the Medium Access Unit (MAU), supports all send and receive functions in accordance with the transmission technology used and takes over the power supply for sensor S1.
- MAU Medium Access Unit
- a data line DL2 leads from the fieldbus interface FBS to one
- KE communication unit that reads telegrams from the data bus line or writes telegrams itself to the DBL data bus line.
- the communication unit KE which is often designed as a modem ASIC, is connected to a microprocessor ⁇ P via a data line DL3.
- Control program of the microprocessor ⁇ P is stored in a non-volatile memory EE.
- the memory EE is a so-called electrically erasable and re-programmable memory (flash memory or flash EPROM).
- the microprocessor ⁇ P is also connected to an interface S, which as
- Connection for an external storage unit eg a portable one Personal computer, serves. Control programs and data can be transferred from external memories to the field device via this interface S. Furthermore, a memory (RAM) and a display and operating unit AB are connected to the microprocessor ⁇ P.
- RAM random access memory
- display and operating unit AB are connected to the microprocessor ⁇ P.
- microprocessor ⁇ P is also connected to a sensor MWA via an A / D converter AD.
- the A / D converter converts the analog measurement signal from the MWA sensor into a digital measurement signal, which is processed in the microprocessor ⁇ P.
- a control line SL leads from a control output A1 of the microprocessor ⁇ P to a switch SR, which is connected to ground with a control input E1 of the fieldbus interface FSB and via a plurality of alternatively switchable resistors R1, R2, R3, R4.
- a stepless adjustment of the resistance is also conceivable.
- the FBS fieldbus interface provides the entire power supply for sensor S1.
- the power supply of sensor S1 can be changed by the resistance value between control input E1 and ground zero.
- the current requirement of sensor S1 depends on whether a measured value is being recorded or not. An increased power requirement (peak load) is necessary during the measurement phase. A lower power supply (base load) is usually sufficient during the measurement breaks.
- the electricity demand is passed on to the individual
- the active control unit can be the process control system PLS or one of the field devices S1, S2, S3, A1 or A2.
- the determination of the electricity requirement can alternatively be carried out by a
- control signals are sent to the individual field devices in accordance with the current utilization of the data bus line, which control the current consumption of the respective field devices.
- the current consumption of the individual field devices can thus be adapted to the process conditions.
- control signals can either be generated by the process control system PLS or, in an alternative embodiment, by one of the field devices.
- the invention also relates to a device for performing the method according to the invention.
- all field devices connected to the data bus line DBL are operated in the basic current mode. Only that Field devices that have an authorization (token) may switch to a peak current mode. After passing on the authorization (token), the respective field device automatically switches back to the basic current mode. It is also conceivable to pass on several tokens between the field devices.
