Product description

1.1 Function

Continuous level measurement with ultrasonic sensors is based on the running time meas­urement of ultrasonic pulses.
Measuring principle
High performance piezoceramic transducers emit focused 70 kHz ultrasonic pulses which are reflected by the product surface. The measurement electronics prepares a precise image of the environment from the reflected ultrasonic pulses. The transducers work both as transmitter and receiver. As receiver, the transducers are high-sensitivity piezo micro­phones.
Meas. dis­tance
emission - reflection - reception
The measurement electronics precisely cal­culates the distance between transducer and medium from the speed of sound and the measured running time of the emitted sound impulse. The distance is then converted into a level-proportional signal and, in conjunction with the sensor parameter settings, made available as a precise, calibrated level value.
Since the speed of sound is subject to tem­perature influence, the transducer also con­tinuously detects the ambient temperature, so that the level is precisely measured even in case of varying ambient temperature.
Output signal
The level-proportional Profibus PA measuring signal is processed and outputted com­pletely digitally. Digital processing of the measuring signal ensures an accuracy which could be never reached by an analogue measuring signal, as the digital signal is always transmitted error-free right up to the last decimal point. Varying line resistances or tiny leakage cur­rents do not influence the accuracy of digital technology. The digital signal is always clear and unambiguous.
The digital signal, mirroring the adjusted measuring range of the sensor, can be modi­fied by various parameter settings.
Display of measured values
As an option, the series 50 ultrasonic sensors can be equipped with an indicating instru­ment for direct, local level survey. The indi­cating instrument shows the precise level by means of the analogue bar graph and the digital number value. In addition to the indica­tion in the sensor, you can have the level displayed with the VEGADIS 50 external indicating instrument at a distance of up to 25 m from the sensor. The external display of measured values operates, like the inte­grated display, independently of the PA out­put signal and can be modified through indi­vidual parameter settings.

1.3 Profibus output signal

PRO
cess FIeld sult of a joint project of thirteen companies and five universities. The companies Bosch, Klöckner-Möller and Siemens played a deci­sive role. The specifications of the bus are described in the protocol layers 1, 2 and 7 of the ISO/OSI reference model and are avail­able from the PNO (Profibus user organisa­tion). Layers 3 … 5 have not yet been developed as a standard, leaving Profibus with far-reaching perspectives for the future.
Today approx. 600 companies make use of Profibus technology and belong to the PNO. Profibus Specification, Profibus DP for Decentralise Periphery and Profibus PA for Process Auto­mation.
As a process automation bus, Profibus PA enables power supply over the bus. Up to 32 sensors can be operated on a shielded two­wire cable that carries both power supply and measuring signal. In Ex areas, up to ten sensors can be connected from the PA level to one two-wire cable (EEx ia).

The DP and PA bus consists of up to 126 master and slave participants. Data are al­ways exchanged from point to point, with the data traffic being exclusively controlled and checked by master devices. Communication is carried out according to the Token-Passing procedure. This means that the master own­ing the Token, can contact the slaves, give instructions, enquire data and cause the slaves to receive and transmit data. After the work is done or after a predetermined time interval, the Token is passed on by the mas­ter to the next master.
Product description
Master-Class 1
is the actual automation system, i.e. the proc­ess control computer or the PLC enquires and processes all measured values.
Master-Class 2
One or several Master-Class 2 can operate in a Profibus network. As a rule, Master-Class 2 devices are engineering, adjustment or visu­alisation stations. The VEGA adjustment soft­ware VVO (VEGA Visual Operating) operates as Master-Class 2 participant on the DP bus and can work on an engineering PC, on an adjustment PC or on the process control computer and can access any VEGA sensor on the PA level.
Instrument master file
A so-called GSD file is attached to a VEGA­SON Profibus sensor. This file is necessary for integrating the sensor into the bus sys­tem. The GSD file (instrument master file) contains, beside the sensor name and the manufacturer, the sensor-specific communi­cation parameters which are necessary for a stable integration of the sensor in the bus. Load the GSD file belonging to the sensor into your bus configuration program. If the GSD file is not available, it can be loaded from the VEGA homepage: http:// www.vega.com. Do not mix up the GSD file with the EDD (Electronic Device Description) necessary for the PDM environment (this can be also found on the VEGA homepage).

1.4 Adjustment

Each measuring situation is unique. For that reason, every ultrasonic sensor needs some basic information on the application and the environment, e.g. which level means "empty and which level "full. Beside this "empty and full adjustment, many other settings and adjustments are possible with VEGASON ultrasonic sensors. The output of echo curves or the calculation of vessel linearisa­tion curves by means of vessel dimensions are only two examples.
Profibus adjustment structure
In the Profibus environment there are differ­ent adjustment concepts and adjustment tools which often differ considerably from manufacturer to manufacturer. From the us­ers point of view, a manufacturer-independ­ent adjustment program which could be directly operated on the Profibus DP, but also from a central point (e.g. the engineering station or the process control) would be ideal.
In the past, only the program "SIMATIC PDM, based on the HART® adjustment struc­ture, could fulfill this wish. However, this pro­gram also has the same limitation as HART®. As with HART®, an instrument-specific data­base is required for comprehensive adjust­ment with PDM (Process Device Managing). Without this, only basic instrument functions, such as live adjustment, are available. In the PDM environment, this instrument-specific database is called EDD (Electronic Device Description). Completely analogous to the HART® environment, the PDM environment also requires a DD (Device Description) for each (with the exception of VEGA HART instruments) sensor.
®
6 VEGASON 51P … 53P
Product description
We are aware of the disadvantages of the HART® environment: for each sensor/partici­pant an individual DD must be loaded which, in addition, must always be the latest and most up-to-date DD. Special adjustment options such as e.g., the output of an echo curve, are available neither with HART® nor with PDM. The SIMATIC-PDM adjustment concept was tailored more to the basic ad­justment functions. Intelligent, communicative sensors, however, make much more addi­tional information available to the measure­ment loop and open up completely new ad­justment possibilities. PDM was not conceived with such things in mind. Really user-friendly adjustment is out of the ques­tion. Thats history now.
The legitimate wish of many Profibus users for a manufacturer-independent adjustment tool without EDD has now been realised with PACTware
TM 1)
. An association of a number of process technology companies developed PACTwareTM: a Process Automation Configu­ration Tool, running different manufacturer software tools under a standardized user interface and adjustment structure. Special­ists call this technology Field Device Tran­scription. Just as different as Windows printer drivers enable operation of completely different printers under one user interface, PACTware
TM
enables operation of all field instruments under one user interface. Instru­ment-specific databases (EDD), like those required for SIMATIC PDM, are not neces­sary.
Adjustment with the adjustment pro­gram VVO - VEGA Visual Operating
Setup and adjustment of the ultrasonic sen­sors is generally done on the PC with the adjustment program VEGA Visual Operating (VVO) under Windows®. The program leads quickly through adjustment and parameter setting by means of pictures, graphics and process visualisations.
The VEGA adjustment software VVO (VEGA Visual Operating) operates either as a subprogram of the host program PACTware (according to the FDT concept) or as an independent adjustment program on any PC, engineering station or process control com­puter.
The adjustment program recognises the sensor type
TM
As a result of this development, three adjust­ment media are now available for VEGA­Profibus sensors:
- adjustment with the PC and the adjustment
program VVO (VEGA Visual Operating) as a stand-alone tool which can, however, also run as a subprogram of PACTware
TM
- adjustment with the detachable adjustment
module MINICOM in the sensor
- adjustment with the SIMATIC PDM adjust-
ment program (requires EDD instrument
Visualised input of a vessel linearisation curve

VEGASON 51P … 53P 7
Product description
The VEGA adjustment program VVO can access the entire spectrum of adjustment options of VEGA sensors and, if necessary, can update the complete sensor software. To do this, the adjustment program must be installed on a PC which is equipped with a Profibus-Master-Class 2 interface card (Softing) (see diagram on following page).
The PC with the Profibus interface card can be connected directly at any point on the DP bus with the standard RS 485 Profibus cable.
The adjustment and parameter data can be saved with the adjustment software on the PC and protected by passwords. If neces­sary, the adjustments can be transferred quickly to other sensors.
In practice, the adjustment program VVO is often installed as a tool on an engineering station or an adjustment station. VVO then accesses via the Profibus interface card (e.g. from Softing) as Master-Class 2 directly via the bus, from the DP level via the seg­ment coupler on PA level and finally to the individual sensor, all VEGA sensors.
No DD necessary for adjustment with VVO
In addition to the instrument master file (GSD), with which a sensor is logged into the Profibus system, the majority of all Profibus sensors also requires along with the specific adjustment software a so-called EDD (Elec­tronic Device Description). This is not the case with VVO. The adjustment software VVO can communicate at any time with all VEGA sensors without requiring a special database. Of course, all other VEGA sensors can be adjusted with the adjustment software as well (4 … 20 mA sensors or VBUS sen- sors). With VEGA sensors, it is not neces­sary to go looking for the latest EDD. This is the essential requirement of a manufacturer­independent adjustment program anticipated by many users.
The above mentioned program PACTwareTM is such a manufacturer-independent automa­tion/configuration tool through which access to instruments of different manufacturers (Krohne, Pepperl + Fuchs, VEGA, VIKA­Bürkert) is possible. The VEGA adjustment software VVO works as an independent tool or as a subprogram of PACTwareTM. Depend­ing on the sensor/instrument currently being accessed, PACTwareTM activates the neces­sary menu options.

Adjustment with the SIMA TIC PDM ad­justment program
To adjust all essential functions of the VEGA sensor with the adjustment station SIMATIC PDM from Siemens, a so-called EDD is re­quired. Without this EDD, only the basic func­tions, such as min./max. live adjustment or the integration time, can be adjusted with the PDM adjustment program. Further important adjustment functions, such as the input of the "

Types and Profibus configuration

2.2 Bus configuration

The type of ultrasonic sensor you use de­pends on the process requirements and the mounting conditions, as well as on the re­quirements of your control, regulative, or process management system.
VEGASON 51P … 53P Profibus ultrasonic sensors are instruments for use in the Profi­bus PA environment. Profile 3 has been im­plemented in the sensors. A measuring system consists of one or several sensors, one or several segment couplers and one DP master computer, such as e.g. a S7 PLC with Profibus interface or a process control sys­tem with Profibus DP-Master-Slot. The processing unit, e.g. the PLC, evaluates the level-proportional, digital measuring signals in a number of evaluation routines and puts them to use process-specifically.
On the following two pages, you will find a schematic diagram of the bus configuration.
The automation system as Master-Class 1 takes complete control of the bus. It reads out all signals cyclically and, if necessary, gives instructions to the participants (e.g. sensors). In addition, further master systems (e.g. visualisation systems or adjustment tools) can be connected to the DP bus. These systems operate as so-called Master­Class 2 participants. Like the Master-Class 1 system, they can read out signals, give in­structions and operate in the acyclical mode.
A DP bus does not allow power supply via the signal cable, whereas the PA bus does. Both DP and PA require at least one screened two-wire cable. The DP bus can additionally have up to 8 cores (screened), through which supply cables can also be led.
Each participant on the bus must have an address. The addressing covers both bus levels. A Profibus DP system can have max. 126 participants, including all participants on the PA level. In practice, each Master-Class 1 computer gets address 1 and the Master­Class 2 computers address 10 … 20. As a rule, the slaves or participants get the ad­dresses 21 … 126. On the Profibus PA level, max. 32 sensors are possible on one PA segment coupler.
Ex environment
In Ex environment, intrinsically safe (EEx ia) PA sensors are used with Ex segment cou­plers. Generally, the number of PA sensors on a segment coupler (Ex or non Ex) de­pends on the current supplied by the sen­sors and from the current offered by the segment coupler. Segment couplers for EEx ia environment provide 90 … 110 mA. The number of sensors results from the sum of:
- the basic power consumption of all sen­sors
- plus 9 mA communication signal
- plus the leakage currents of all sensors
- plus a recommended current reserve (approx. 10 mA)
The min. basic current has been set at 10 mA according to the Profibus specification. VEGA Profibus sensors draw a constant basic current of 10 mA and operate without leakage current requirement. This allows up to 10 VEGA sensors in Ex environment to be operated on one segment coupler.

Beam angle and false echoes

Therefore, in practical application, the trans­ducer has to be oriented so that lowest pos­sible false echo signal strength is achieved. Only giving attention to the size of the useful echo is usually not adequate under difficult measuring conditions. In most cases, a low false echo level enables the sensor to reliably pick up the useful echo. With the adjustment software VVO on the PC, you can view the echo image (see chapter "6.2 Adjustment with VVO – Sensor optimisation – Echo curve“).
Mounting and installation
On flat vessels, mounting is usually done on a very short DIN socket piece. Reference plane for flange versions is the instrument flange. The transducer should protrude out of the flange tube.

Narrow, uneven shafts, wells and vessel openings with very rough walls and shoul­ders make ultrasonic measurement ex­tremely difficult due to strong false echoes. This problem can be overcome by using an extended socket piece or a complete meas­uring tube (see chapter "4.5 Socket exten­sion).

Example of a socket extension or measuring tube in a shaft
Very good measuring results can be attained with a measuring tube in continuous narrow shafts, see figure. The applied measuring tube must have smooth walls inside (e.g. PE sewage pipe) and a diameter ³ 200 mm. This arrangement works well as long as the inside of the measuring tube collects no dirt or buildup (cleaning necessary). You might want to consider using hydrostatic pressure transmitters or capacitive measuring probes. Either the measuring tube should never be immersed in the medium, or it must always be immersed, so that the measurement is carried out exclusively in the tube.

4.3 Measurement of solids

Flange mounting
As with applications for liquids, the instrument can be mounted on a short DIN socket con­nection on vessels for solids. The transducer axis should only point to the vessel outlet or should be directed perpendicular to the product surface and must be very short (< 100 mm).

Mounting boss
Different filling conditions often lead to a vary­ing product surface orientation. This causes the useful echo to vary in quality. For this reason, the transducer should be mounted in such a way that, even in the empty vessel, the false echo intensity is as low as possible. You can view the echo curve on the PC with the adjustment program VVO (see chapter "6 Setup/Adjustment with the PC/Sensor optimisation/Echo curve).

For threaded process connections (type 51,

Material heaps
Large material heaps are usually measured with several instruments, which can be mounted on e.g. traverse cranes.

Ultrasonic sensors require a min. distance to the product or solid. Take the min. distance into account in your planning. In some situa­tions, it is possible to reach the required min. distance, and hence the desired filling height, with a socket extension. However, the socket extension increases the noise level of the ultrasonic signal at the extension outlet and can interfere with the measurement. Only use a socket extension if all other possibilities have to be excluded. Carry out the extension as shown in the following illustration.
Mounting and installation
For nonadhesive measured products, a socket extension in the form of a measuring tube can be permanently submerged in the product. The ultrasonic measurement is then made exclusively in the measuring tube and works very well without interference from other vessel installations (see page 26 "Pump shaft).

Chamfer and deburr the socket carefully and make sure it has a smooth inner surface. The socket should not protrude into the meas­ured product, in case buildup can form on the socket through pollution or product resi­dues.
Socket piece should not be immersed into adhesive products (figure: VEGASON 53)
The socket diameter should be as large and the socket length as small as possible. To minimise false echoes, make sure that the socket outlet is burr-free.

4.6 False echoes

The mounting location of the ultrasonic sensor must be selected such that no installations or inflowing material are in the path of the ultra­sonic impulses. The following examples and instructions show the most frequent measur­ing problems and how to avoid them.
Vessel protrusions
Vessel forms with flat protrusions can, due to their strong false echoes, adversely effect the measurement. Shields above these flat protrusions scatter the false echoes and guarantee a reliable measurement.
Correct Wrong
Vessel protrusions (slope)
Intake pipes, e.g. for the mixing of materials ­with a flat surface directed towards the sen­sor - should be covered with a sloping shield. This shield will scatter false echoes.
Vessel installations
Vessel installations such as, for example, a ladder, often cause false echoes. Make sure when planning your measurement loop that the ultrasonic signals have free access to the measured product.
Correct Wrong
Ladder
Vessel installations
Ladder
Struts
Struts, like other vessel installations, can cause strong false echoes that are superim­posed over the useful echo signals. Small shields effectively hinder a direct false echo reflection. These false echoes are scattered and diffused in the area and are then filtered out as "echo noise by the measuring elec­tronics.

Mounting and installation
The expected max. high water determines the installation height, to ensure the min. distance of the transducer even with the highest water level. The low water basin ledges should be covered with a shield in the transducer area to filter out echoes from exposed basin surfaces.
Min. distance high water
If the sensor is mounted too close to the vessel wall, buildup and adhesions of the measured product to the vessel wall can cause false echoes. Position the sensor at a sufficient distance from the vessel wall. Please also note chapter "4.1 General instal­lation instructions“.

Do not mount the instrument in or above the filling stream. Ensure that you detect the product surface and not the inflowing mate­rial.
Buildup
Strong turbulence in the vessel, e.g. by pow­erful stirrers or intense chemical reactions, seriously interfere with the measurement. A surge or bypass tube (illustration) of suffi­cient size always allows, provided the prod­uct causes no buildup in the tube, a reliable measurement even with strong turbulence in the vessel.

Wrong orientation to the product
Weak measuring signals are the result if the sensor is not directly pointed at the product surface. Orient the sensor axis perpendicu­larly to the product surface to achieve opti­mum measuring results.

Mounting and installation
If the sensor is mounted too close to the vessel wall (dimension A in diagram), strong false echoes can be caused. Buildup, rivets, screws or weld joints on the vessel wall su­perimpose their echoes to the product or useful echo. Please ensure the sufficient distance of the sensor to the vessel wall, depending on the maximum measuring dis­tance (dimension B in diagram).
In case of good reflection conditions (liquids, no vessel installations), we recommend de­termining the sensor distance according to
. At a max. meas. distance of e.g. 10 m, the distance of the transducer (according to curve 1) should be approx.
1.5 m.
In case of solids with poor reflective proper­ties, determine the distance to the vessel wall according to . Under very bad measuring conditions (rough vessel walls, struts), it might be necessary to in­crease the distance to the vessel wall, or to also filter out the false echoes by storing them in memory, thereby adapting the sensor more precisely to the environment.

Parabolic effects of rounded or arched vessel tops
Round or parabolic tank tops act like a para­bolic mirror on the signals. If the sensor is placed at the focal point of such a parabolic tank top, the sensor receives amplified false echoes. The optimum location is generally in the area of half the vessel radius from the centre.

5 Electrical connection

5.1 Connection – Connection cable
– Screening
Safety information – Qualified person­nel
Instruments which are not operated with protective low voltage or DC voltage must only be connected by qualified personnel. This is also valid for the configuration of measuring systems planned for Ex environ­ment.
As a rule, do all connecting work in the com­plete absence of line voltage. Always switch off the power supply before you carry out connecting work on the radar sensors. Pro­tect yourself and the instruments.
Connection cables and bus configura­tion
Note the Profibus specification. The connec­tion cables must be specified for the ex­pected operating temperatures in the plant and must have an outer diameter of 6 12 mm, to ensure the seal effect of the cable entry on the sensor.
For power supply and bus communication, a two-wire cable acc. to the Profibus specifica­tion (up to max. 2.5 mm2 conductor cross­section) can be used. The electrical connection on the sensor is made by means of spring-loaded terminals.
In a laboratory setup, a Profibus system will also work with standard, unshielded two-wire cable. In practice however, an automation network and bus system can only be pro­tected reliably against electromagnetic inter­ference with screened cable. Acc. to the Profibus specification (IEC 1158-2) screened and twisted cables are prescribed.
All participants are connected in line (seri­ally). At the beginning and end of the bus segment, the bus is terminated by an active bus termination. On the DP bus level, most participants already have a bus termination implemented. With more than 32 participants on the DP level, a so-called repeater must be used to open and combine another DP level with a max. of 32 participants. On the PA bus branch of the segment coupler, the PA ultra­sonic sensors work also with max. 32 partici­pants (Ex max. 10 participants).
A PA sensor can work only in conjunction with a Profibus DP system, to which a Profibus PA subsystem is connected. A PA Profibus par­ticipant must consume min. 10 mA supply current.
Connection cable and cable length
Connection cables must correspond to the Profibus specification and the FISCO model. The sensor cable must be in conformity with the values of the reference cable acc. to IEC 1158-2:
0.8 mm2; R Z
= 80 120 W; damping = 3 dB/km;
31.25kHz
C
asymmetric
The max. cable length first of all depends on the transmission speed:
up to 32 kbit/s: 1900 m Profibus PA
up to 94 kbit/s: 1200 m Profibus DP up to 188 kbit/s: 1000 m Profibus DP up to 500 kbit/s: 500 m Profibus DP up to 1500 kbit/s: 200 m Profibus DP up to 12000 kbit/s: 100 m Profibus DP
= 44 W/km;
DCmax.
= 2 nF/km.
VEGASON 51P 53P 35
Electrical connection
The distributed resistance of the cable, in conjunction with the output voltage of the segment coupler and the current requirement (VEGASON 10 mA) or the voltage require­ment (VEGASON 9 V) of the sensor, deter­mines the max. length of the cable.
In practical application of a PA bus branch, the max. length of the cable is also deter­mined (beside the required supply voltage and max. current consumption of all partici­pants on the PA bus branch) by the bus structure and the type of segment coupler used.
The cable length results from the sum of all cable sections and the lengths of all stubs. The length of the individual stubs must not exceed the following lengths: 1 12 stubs 120 m (Ex: 30 m) 13 18 stubs 60 m (Ex: 30 m) 19 24 stubs 30 m (Ex: 30 m)
No more than 24 stubs are permitted, whereby each branch longer than 1.2 m is counted as a stub. The total length of the cable must not exceed 1900 m (in Ex version 1000 m).
Ground terminal
The electronics housings of the sensors have a protective insulation. The ground terminal in the electronics is galvanically connected with the metallic process connection. For sensors with a plastic thread as process fitting, the sensor grounding must be made by a ground connection to the outer ground termi­nal.
Screening
"Electromagnetic pollution caused by elec­tronic actuators, energy cables and transmit­ting systems has become so pervasive that shielding for the two-wire bus cable is usually a necessity. According to the Profibus speci­fication the screening should be made on both ends. To avoid potential equalisation currents, a potential equalisation system must be provided in addition to the screen­ing.
According to specification, we recommend the use of twisted and screened two-wire cable, e.g.: SINEC 6XV1 830-5AH10 (Sie­mens), SINEC L26XV1 830-35H10 (Siemens), 3079A (Belden).
Alternatively, when grounding at both ends in non-Ex areas, the cable shielding can be connected on one ground side (in the switch­ing cabinet) via a capacitor (e.g. 0.1 µF; 250 V) to the ground potential. Make sure that the ground connection has the lowest possible resistance (foundation, plate or mains earth).
Profibus P A in Ex environment
When used in Ex area, a PA bus with all con­nected instruments must be carried out in intrinsically safe protective class "i. Four-wire instruments requiring a separate supply must at least have an intrinsically safe PA connection. VEGA sensors for PA-Ex envi­ronment are generally "ia two-wire instru­ments“.
36 VEGASON 51P 53P
Electrical connection
In the so-called Fieldbus Intrinsically Safe Concept (FISCO) the general conditions for an Ex safe bus configuration have been laid down. Therein, the participants and the bus cables with their respective elec. data have been determined, so that the linking of these components always meets the Ex require­ments. The more time-consuming Ex calcula­tion normally required is therefore not necessary. Build your Ex bus according to the IEC standard 1158-2.
The Ex segment coupler delivers a controlled power supply to the PA bus. All other compo­nents (field instruments and bus terminators) are only consumers. A field instrument must consume at least 10 mA. Ideally, an individual sensor should not consume more than 10 mA so that the number of instruments can be as large as possible.
VEGA PA sensors, whether Ex or non Ex, consume a constant current of 10 mA. Ac­cording to the Profibus specification, this is the minimum participant current. With VEGA sensors it is therefore possible to connect 10 sensors (also in Ex environment) even with a limited energy supply from the Ex segment couplers.
Watch out for potential losses
Due to potential losses, earthing on both sides without potential equalisation system is not allowed in Ex applications. If an instru­ment is used in hazardous areas, the re­quired regulations, conformity and type approval certificates for systems in Ex areas must be noted (e.g. DIN 0165). Please also note the approval documents with the safety data sheet attached to the Ex sensors.

5.2 Sensor address

In a Profibus system composed of Profibus DP and Profibus PA subsystem, each partici­pant must have a unique address. Each participant, whether master or slave, is accessed by means of its own address in the bus system. The address of a partici­pant, whether on DP or PA level, should be assigned before connecting to the bus, be­cause an address can be used only once. If an address is used twice, interference will be caused in the bus.
The address of an ultrasonic sensor can be set in two ways:
- with the adjustment software VVO (soft­ware addressing) or
- with the DIP switch block in the sensor (hardware addressing).
VEGA Profibus sensors are dispatched with the address set at 126 (all DIP switches to "ON). Remember, in a Profibus system there are max. 126 participants possible. When the DIP switch is set to address 126 (or higher), the address can be adjusted with the adjust­ment software VVO, the adjustment module MINICOM or another configuration tool (e.g. PDM). However, there can be only one sen­sor on the bus with address 126 (delivery status) during address assignment via soft­ware. For that reason, hardware addressing (DIP switch) before connection to the bus is recommended.
Hardware addressing
The DIP switches generate an address number in the binary system. This means that, from right to left (ascending), any switch represents a number twice as high as the previous switch on the right. The corre­sponding number in the decimal system results from the sum of all switches set to "ON. In the illustration you see the decimal number that corresponds to each individual DIP switch.
DIP switch 8 corresponds to the number 128, switch 1 corresponds to the number 1 and switch 3 corresponds to the decimal number
4.

Software addressing
The DIP switches must be set to an address of 126 255, i.e.
- either all DIP switches are set to "ON“, corresponding to address 255 (delivery status)
- or only DIP switch 8 is set to "ON, corre­sponding to address 128.

5.3 Connection of the sensor

Electrical connection
After mounting the sensor at the measure­ment location according to the instructions in chapter "4 Mounting and installation, loosen the closing screws on top of the sensor. The sensor lid with the optional indication display can then be opened. Unscrew the sleeve nut and slip it over the connection cable (after removing about 10 cm of insulation). The sleeve nut of the cable entry has a self-lock­ing ratchet that prevents it from opening on its own.

6.1 Adjustment media

In chapter "1.4 Adjustment the Profibus adjustment structure was briefly explained and the adjustment media for VEGA Profibus sensors were shown. All VEGA Profibus sensors operate in profile 3 and can be ad­justed with:
- the adjustment program VVO on a PC with Profibus card
- the adjustment program PACTwareTM, in which VVO runs as a subprogram
- the Siemens software PDM in conjunction with an EDD (Electronic-Device-Descrip­tion)
- the adjustment module MINICOM in the sensor.
Adjustment with VVO on the PC
The adjustment program VVO enables user­friendly adjustment of VEGA Profibus PA sensors. All functions and options of sensor adjustment are possible. The program runs under Windows® on a PC with a Profibus­Master-Class 2 interface card on Profibus DP level as Master-Class 2 tool. The VVO pro­gram accesses the VEGA PA sensors via the DP bus, the segment coupler and the PA bus.
Adjustment with PDM
The sensors can be adjusted completely with PDM. However, some user-friendly functions and many special features, like e.g. display of an echo curve, are not available. In addi­tion to the PDM software, an EDD (upon request available from VEGA) is required for each sensor type. The adjustment instruc­tions for PDM are described in the PDM documentation.
Adjustment with the adjustment module MINICOM
With the adjustment module MINICOM, you adjust the individual sensor directly on the sensor or in the external indicating instrument VEGADIS 50. The adjustment module MINI­COM enables (with the 6 key adjustment field with text display) all essential functions for parameter setting and adjustment.
Adjustment with P ACT ware
The adjustment with PACTwareTM corre­sponds to VVO adjustment, however in this case, VVO runs as a subprogram of PACTwareTM. The adjustment instructions can be found in the documentation of PACTwareTM.

6.2 Adjustment with VVO

Before you can adjust the sensors with the adjustment program VVO (VEGA Visual Operating), they must be integrated into the Profibus system. First of all address the sensors (chapter "5.2 Sensor address) and connect them to your PA segment. With the attached GSD file you integrate the sensors into your system.
To adjust the VEGA sensors with the adjust­ment software VVO, the PC or the adjustment station on which VVO is installed must be equipped with a Profibus DP interface card (e.g. of Messrs. Softing). The PC or the ad­justment station communicates then as Mas­ter-Class 2 participant on the DP bus with the VEGA sensors on the PA bus segment.
To connect the PC to the DP bus, a standard RS 485-DTE interface cable (Data Terminal equipment) is required. With the cable you connect the DP interface card to the bus or to the segment coupler.

Setup
Configuration and parameter adjust­ment
During setup of the sensor you will be con­fronted with two terms: "Configuration and "Parameter adjustment. The measuring sys­tem is first configured and then made ready for operation by parameter adjustment.
Configuration
The term "Configuration means the basic adjustments of the meas. system. You inform the meas. system about the application (level measurement, gauge, distance ), the measurement loop name and the DCS output address of the sensors. The configuration corresponds to an electronic wiring and labelling of your sensor or, in other words, telling the system which sensor for what application and where.
Parameter adjustment
After the configuration, you carry out the parameter adjustment on each individual sensor. This means adjusting the sensors to the respective operating range and adapting them to the specific application. You inform the sensor which product distance (which level) is "empty and which "full. This is called adjustment. Here you choose in which physi­cal unit (volume, mass) and unit of measure­ment (m3, gal, liters ) the adjusted measured value should be outputted. In the submenu "Sensor optimisation you inform the sensor electronics about the actual envi­ronment, such as e.g. quick changes of the measured value, foam generation, gas strati­fication, solid or liquid.
Before starting the setup:

.
The sensor electronics has two characteris­tics points (at min. and max.) from which a linear proportionality between product dis­tance and the percentage of filling of the vessel is generated. Of course, the characteristics points must not necessarily be at 0 % and 100 %, however they should be as far apart as possible (e.g. at 20 % and at 80 %). The difference be­tween the characteristics points for the min./ max. adjustment should be at least 20 mm product distance. If the characteristics points are too close together, the possible measur­ing error increases. Ideal would be to carry out the adjustment as shown in the example, at 0 % and at 100 %.

4.58 m and is between 5.85 m (empty) and
1.27 m (full), see the following presentation.
5.85 m meas. distance correspond to 0 % level. 1.27 m meas. distance correspond to 100 % level. The span is therefore 4.58 m (5.85 m – 1.27 m = 4.58 m).
A percentage value of 95.79 % then means that 4.387 m of the adjusted span (4.58 m) have been reached:
4.58 0.9579 = 4.387 m.
The distance (product distance), outputted by the sensor, if you have chosen "

is then:
5.85 – (4.58 0.9579) = 1.463 m.
If the index markers or value pairs of your vessel are not known, you must gauge the vessel incrementally or calculate it with the vessel calculation program of VVO.
Defining the linearisation curve by incre­mental filling
In the characteristics of the example, you see four index markers or value pairs. There is always a linear interpolation between the index markers. The example vessel consists of three cylindrical segments of different height and diameter. The middle segment has a considerably smaller diameter.

In the following example, the tank calculation program calculates the linearisation curve of a vessel corresponding to the vessel in the previous gauging example.

you can start the vessel calculation program. With the vessel calculation program you can calculate (using dimensions from the technical drawings of the vessel) the correlation of filling height to filling volume. If the curve is defined this way, gauging by incremental filling is not neces­sary - your sensor can then output volume as a function of level.

You will get the calculated linearisation table after a short calculation time. By means of 32 linearisation points, a function correlating vessel volume to filling height is outputted.

Tank 1 m (d)

In addition to the PC, you can adjust the sensors with the small, detachable adjust­ment module MINICOM directly in the sensor.
With the adjustment module MINICOM, only the sensor-relevant adjustment such as e.g. scaling of the sensor display, operating range, meas. conditions, sensor display scaling or false echo storage are possible. However, not possible are all adjustment steps relating to configuration, conditioning and signal processing (configuration of the inputs and outputs, linearisation curves, simulation ). This is only possible with the PC.
The adjustment module MINICOM is adjusted with six keys. A small display shows you, apart from the measured value, a short mes­sage on the menu item or the entered value of a menu adjustment.
The volume of information of the small display, however, cannot be compared with that of the adjustment program VVO, but with the help of the menu schematic for MINICOM, you will quickly find your way through the adjustment structure. In time, you might even be able to carry out your adjustments with the small module faster and more efficiently than with the PC.

Adjustment steps
On pages 70 and 71 you will find the com­plete menu schematic of the adjustment mod­ule MINICOM. Set up the sensor in the numbered se­quence:
1.Address
2. Measurement in gases
3. Operating range
4. Adjustment
5. Conditioning
6. Meas. conditions
7. False echo storage (only required when
errors occur during operation).
8. Indication of the useful and noise level
9. Outputs Short explanations to the setup steps 1 … 9 follow.
1. Address
Choose a free bus address with the DIP switch (see chapter "5.2 Sensor address).
VEGASON 51P 53P 65
Adjustment is only necessary if the measure­ment is made in gases deviating from air (CO2, He, etc.). When measuring in gases, sound the distance of the sensor to the prod­uct surface and enter this in the menu item "Measurement in gases. The sensor can then take the modified (compared to air) sonic velocity in gases into account and output correct levels.
Without special adjustment, the operating range corresponds to the measuring range. Generally, it is useful to choose a slightly wider range (approx. 5 %) for the operating range than for the measuring range.
Example: Min./max. adjustment: 1.270 5.850 m; adjust operating range to approx.
1.000 6.000 m.
Setup
You can carry out the adjustment with or without medium. Generally you will carry out the adjustment without medium, as you can then adjust without a filling/emptying cycle.

(max. adjustment)
Now you make the max. adjustment (upper product distance) (example: 100 % and
1.270 m product distance). First enter the per­centage value and then the product distance corresponding to the percentage value.
The difference between the adjustment val­ues of the lower product distance and the upper product distance should be as big as possible, preferably at 0 % and 100 %. If the values are very close together, e.g. lower product distance indication at 40 % (3.102 m) and upper product distance adjustment at 45 % (3.331 m), the measurement will be inaccurate. A characteristic curve is gener­ated from the two points. Even the smallest deviations between actual product distance and entered product distance will consider­ably influence the slope of the characteristic curve. If the adjustment points are too close together, small errors inflate to considerably larger ones when the 0 % or the 100 % value is outputted.

7.1 Simulation

Simulation with VVO
To simulate a certain filling, you can call up the function "Simulation on the adjustment module MINICOM, in the software program VVO or on the signal conditioning instrument.
You simulate a vessel filling and thereby a certain sensor current. Please note that con­nected instruments, such as e.g. a PLC, react according to their adjustments and will probably activate alarms or system func­tions.
If you start the simulation mode with the ad­justment program VVO on the PC, the simu­lated level is outputted until you quit the simulation mode.
Simulation with MINICOM
If you start the simulation mode on the adjust­ment module MINICOM, the sensor returns to standard operating mode after one hour.

8 Function diagram and PA parameters

The following parameter listing and the func­tion diagram are used for setup with the automation system, if no adjustment software is available. The listing represents the pa­rameters of the function block and trans­ducer block and is only meant for very experienced Profibus users. Make sure that all VEGA sensors are profile 3 sensors. Nor­mally, you will carry out the setup of the sen­sors with greater ease using the VEGA adjustment software VVO or the adjustment module MINICOM in the sensor.

8.1 Parameter listing

The PA parameters and the function diagram are generally not necessary for setup and are used to extend the knowledge of inter­ested users who are able to read the meas­ured values from the sensor into their processing system without adjustment tool.
