1 Product description

1 Product description

1.1Configuration

Each instrument can be optionally equipped with an RS232 or an Ethernet interface.These interfaces are permanently integrated and cannot be retrofitted or exchanged.Connection is carried out via an RJ-45 plug on the lower side of the respective instrument.

	1.2 Principle of operation
Application area	RS232 interface
	The RS232 interface is particularly suitable for easy modem connec-
	tion for remote enquiry of measured values.For this purpose, external
	analogue, ISDN and GSM modems can be used.
	Ethernet interface
	With the Ethernet interface, instruments can be connected directly to
	an existing PC network.Each instrument is assigned its own IP ad-
	dress at which it can be accessed from anywhere in the network.

1.3 Adjustment

To adjust the instrument, the configuration software PACTware and a suitable instrument driver (DTM) according to FDT standard are required.In addition, the DTMs can be integrated in other frame applications according to FDT standard.As an alternative, adjustment of the basic functions is possible via the integrated indicating and adjustment module.

All device DTMs fromVEGA are available as a free-of-charge standard version and as a full version that must be purchased.In the standard version, all functions for complete setup are already included.An assistent for simple project configuration simplifies the adjustment considerably.Saving/printing the project as well as import/ export functions are also part of the standard version.

In the full version there is also an extended print function for complete project documentation as well as a save function for measured value and echo curves.In addition, there is a tank calculation program as well as a multiviewer for display and analysis of the saved measured value and echo curves.

The standard version is available as a free-of-charge download under http://www.vega.com.The full version is available on CD from the agency serving you.

The licence regulations allow you to copy aVEGA DTM any number of times and use it on any number of computers, as long as you are using the standard version.The full version must be bought separately per computer and installation.

Dynamic IP-address (DHCP)

For instruments with integrated Ethernet interface, the automatic addressing via DHCP is preset, i.e.the IP address must be assigned by a DHCP server.Generally the instrument is contacted via the Host name.As an alternative, it is also possible to enter a static IP addr. with Subnet mask and optional Gateway addr.

Note:

The setting/modification of these network parameters will be only taken over, i.e.become effective, after a restart (interruption of power supply and restart).

Enquire of your responsible network administrator the type of addressing wished in your network and, if necessary, further specifications.The following adjustment options and parameters are available:

In this mode, all necessary parameters are assigned automatically to the signal conditioning instrument by a DHCP server available in the network.These parameters, e.g.the IP address, are thus not known to the user.What is more, they can change whenever the power supply is interrupted.That is why a host name must also be used, via which the instrument can be addressed in the network.Further parameters such as subnet mask, gateway or DNS server address do not have to be entered with automatic addressing.Every instrument is set to DHCP at the factory.

Static (fixed) IP address If no DHCP server is available (e.g.when connecting directly to a PC via cross-over cable) or automatic addressing is not wanted, the IP addresses are entered manually in each instrument.Your responsible network administrator provides a corresponding IP address with suitable subnet mask.

Subnet mask	The subnet mask together with the IP-address determines which
	network segment the instrument should belong to.
Standard gateway	A gateway connects individual network segments – data traffic can
	thus be forwarded to destinations outside the local network segment.
	Entry of a gateway address is only required when manually assigning
	an address and for large networks.
Host name	With automatic addressing via DHCP, it is necessary to assign a host
	name because the IP address is generally not known or can change.
	By default, the host name consists of the serial number plus "VEGA-"
	in front.Anything can be entered as a host name, for example the
	name of the measurement loop or the plant.The host name must only
	include letters and numbers without spaces.Only the hyphen "-" is al-
	lowed as a special character.The first character must be a letter.The
	host name can have a maximum of 16 characters.
DNS server	The DNS server is responsible for assigning the IP address and the
	host name.This is particularly important with automatic addressing
	because network devices are accessed via the host name.Entry
	of a DNS server address is only required with manual addressing

Create a project automatically

4.1Start PACTware

Start PACTware via theWindows start menu.In the standard setting, it is not necessary to enter a user name and a password.If user name/ password is requested, you can assign various users with different rights and assign a password under the PACTware menu item "Extras - User administration".

Information:

To ensure that all instrument functions are supported, you should always use the latest DTM Collection.Furthermore, not all of the described functions are always included in older firmware versions.For many instruments, the latest instrument software can be downloaded from our homepage.The transfer of the instrument software is carried out via PACTware.A description of the update procedure is also available in the Internet.

4.2Create a project

Starting point for the adjustment of all types of field devices is the partial or complete imaging of the device network in a PACTware project. This device network can be created automatically or manually and is displayed in the project window.

With simple device structures

For simple device structures, for example, a direct connection of the PC via aVEGACONNECT 4 with aVEGA sensor, it is not necessary to create the device network, but as an alternative you can directly click the desktop link "VEGA-USB-Scan".If PACTware is opened via this link, the connected sensor is automatically identified and the suitable DTM appears in the PACTware window in online mode.All PACTware adjustment elements are faded out so that only the information of the DTM relevant for the actual parameter adjustment are visible.

With complex device structures

With complex device structures, the connection is carried out via the VEGA project assistant.TheVEGA project assistant is a manufactur- er-specific extension module for PACTware.It is part of eachVEGA DTM installation package and is installed automatically.By means of theVEGA project assistant, the connected instruments are identified automatically and integrated into the PACTware project.For this, only an online connection to the respective instruments is necessary.

TheVEGA project assistant is opened from the PACTware menu bar under "Project - VEGA project assistant".The window "VEGA project assistant" opens and you only have to select the requested interface for automatic generation of the project.If only one instrument is connected to the selected interface, the DTM parameter adjustment window will be opened automatically and the device data loaded.

You can find further information on how to use theVEGA project assistant in the corresponding online help.The online help can be opened directly from the window "VEGA project assistant".

Fig. 1: Project assistant

Create a project manually Even when instruments that are to be parameterised are not yet available or connected, the project can be created manually (offline operation).All DTMs installed on the PC are displayed in the device catalogue.The DTMs usually have the same names as the instruments that can be adjusted with them.For a better overview, the device catalogue is divided into different subgroups.On the upper level, the manufacturers of the respective DTMs appear first.Below, the DTMs are divided into different function categories such as "Driver", "Gateway" and "Device".

To create a project in the project window, paste in the DTMs from the instrument catalogue - one DTM for each actually used instrument. The entry HOST-PC is the starting point for pasting in the DTMs.The requested DTM can be brought over from the instrument catalogue to the project window with a double click or Drag and Drop.In the project window you can change the names of the selected instruments for better differentiation.If the project window or the instrument catalogue are not visible, they can be activated in the menu bar under "View ".

•Automatic transmission of levels, thresholds and fault messages via e-mail or SMS

•Remote enquiry of several tank farms via modem

•Measured value enquiry via Modbus-TCP

•Measured value enquiry via ACSII protocol

•Read out of measured value files via http

	5.2 Inventory enquiry via network and browser
Requirement	The stock of a tank farm should be measured and monitored continu-
	ously.The measured values should be available to the scheduler and
	the sales department.In addition, a message should be triggered
	automatically if a level drops below a certain value.
Solution	One or more signal conditioning instruments with Ethernet interface
	enquire the respective sensors cyclically.The measured values are
	processed in the signal conditioning instrument and transferred in the
	requested form and unit to the integrated web server.The measured
	values can now be displayed on the computer of every user in the
	company network.In addition, the required minimum quantity is en-
	tered for each vessel.An e-mail is sent to the appropriate person via
	the company-internal mail system if a level falls below a certain value.

	5.3 Inventory enquiry/VMI via WEB-VV
Requirement	A supplier would like to keep track of the tank stock levels of his
	customers and replenish them on his own whenever necessary.Via a
	display that is updated several times daily, he has access to the level
	data of the previous days or weeks.The supplier can thus assess the
	requirements/consumption of his customers and plan his deliveries

accordingly.This allows him to do anticipatory purchasing and also better utilize the capacity of his truck fleet.In addition, a message should be sent if the level in any tank falls below a certain predefined minimum value. Using this method, the supplier can always guarantee his customers a sufficient supply of raw materials for production without their having to bother with purchasing and ordering.And he has the added benefit of long-term customer retention and continuous orders.

	Fig. 5: Remote enquiry via WEB-VV
Solution	A signal conditioning instrument with serial interface and modem
	(conventional telephone network or GSM) is installed at each cus-
	tomer.The measured values are transmitted automatically from each
	signal conditioning instrument to the centralWEB-VV server atVEGA.
	As an alternative, the measured value transmission can be also car-
	ried out via the Ethernet interface and the existing company network.
	The measured values can now be retrieved worldwide quickly and
	easily by any number of (authorized) persons via Internet and web
	browser.The current measured values as well as the history data are
	available as a line graph.A certain alarm threshold can be defined for
	each measurement loop.If a level falls below a predetermined value,
	an e-mail or SMS can be sent to certain persons.

6 PC/DCS values

6 PC/DCS values

6.1General information

PC/DCS outputs are used as digital outputs for transmission of measured value information.The data can be transmitted to a superordinate PC, DCS or processing system via the RS232/Ethernet interface. The values can be sent e.g.as e-mail or read out via ModbusTCP in case of an existing Ethernet interface.The HTML pages of the signal conditioning instrument also show the measured values of the PC/ DCS outputs.The adjustment of the data format and the reference value is carried out with PACTware and the corresponding DTM.In the parameter adjustment page "PC/DCS" the reference value and the data format are selected;in addition, the option "In case of error: transmit error code instead of measured value" can be activated.

Reference value	With the reference value you determine which measured value is
	used as input signal for the PC/DCS output.The following reference
	values are available depending on the instrument:
	•	Sensor value
	•	Percent
	•	Lin. percent
	•	Scaled
	•	Totalizer
Data format	With "Data format", the format of the PC/DCS value is determined.
	Here you determine how many decimal positions will be transmitted.
	This setting is important, e.g.with Modbus-TCP (filing of the meas-
	ured value as 2 Byte short).The PC/DCS value is then transmitted in
	the integer format, i.e.the value must be within the range of -32767
	and +32767.
	Example: The sensor value of a pressure transmitter should be
	transmitted as PC/DCS value.The meauring range of the sensor is
	between -0.5 bar and +0.5 bar, the value should be transmitted with
	two positions after the decimal point.The following settings must
	be carried out:The sensor value must be selected as "Basic meas.
	value" and the selection #.## as "Data format".With these settings,
	the sensor value -0.5 bar is transmitted as PC/DCS value -0.5 bar.
Fault	If " In case of error: send error code instead of measured value " is ac-
	tivated, the number of the error code is sent instead of the measured
	value.These numbers correspond to the numbers of the instrument
	status.

Example: With error E008, value 8 is transmitted instead of the measured value.

7Measured value enquiry via Web browser/ http

7.1 General information

With an individual web browser (e.g.Internet Explorer) all measured values available in the signal conditioning instrument can be displayed in the requested form and unit.The measured value indication is carried out as HTML chart.Within a company network the enquiry is made via Ethernet.If a remote enquiry is necessary, a signal conditioning instrument with RS232 interface and connected modem is used.

The measured value enquiry can be also carried out via an individual http-capable software, e.g.Excel.

7.2 Access protection

To prevent unauthorised access to the measured values, the signal conditioning instrument can be provided with access protection.Use the web browser and enter the host name or the IP address of the instrument.Under "Settings - General" you can define the user name and the password and activate the access protection.When the page is called up, the default user name and password are asked for first of all.Enter "VEGA" for user name and password.Now you can activate the access protection for measured value enquiry and enter your own password.

The access protection applies also to measured value and instrument trend files which can be called up via http.

Note:

This access protection only prevents measured value enquiry via web browser.If the configuration of the signal conditioning instrument also needs to be protected against unauthorized access, a second access protection is available.This protection is configured with PACTware or the respective DTM.

conditioning instrument is displayed with all measured values in your browser window.This measured value enquiry can be carried out on any number of PCs in your network.

Fig. 6: Measured value indication by means of Internet Explorer

7.4Measured value enquiry via web browser/ RS232

Measured value enquiry via RS232 interface and PPP (Point to Point Protocol) is used if no internal company network or other direct connection is available.PPP is a transmission standard for serial connection between two computers (points).A dial-up line (telephone line) with a modem is usually used for this.

Measured value enquiry by means of web browser is a dial-in connection.The signal conditioning instrument accepts an incoming call and reacts to the calling host like an Internet Service Provider (ISP).This allows data exchange with the signal conditioning instrument via http. The dial-up connection makes it possible to access the HTML pages of the signal conditioning instrument with a web browser.

If a telephone connection is not available, a GSM wireless modem with RS232 interface can also be used.In this case, a GSM mobile phone contract with the option of data transmission is required.Make sure that your location is sufficiently covered by the network of the mobile network operator.In addition, the PIN of the SIM card used must be deactivated.
