Product description

1.1 Application

The VEGACOM 557 is an efficient and easyto-use interface converter (Gateway) for your measurement applications. It is used for conversion of the VEGA-specific protocols of DISBUS and LOGBUS into standard data formats.

The existing version is used for connection of level or pressure measuring systems to Profibus DP systems such as

- processing systems (DCS)

- personal computers (PC)

- stored program control (PLC). In addition, it is used for connecting a PC for configuration or visualisation via the VEGA adjustment software.

If connection is made to external systems, there is the possibility of calling up measurement data and status information of the measuring systems via the master of the external system. The coupling of the external system is made via the connections on the rear of the instrument. This data traffic requires that special measures (described in this manual) be taken in setting up the master of the external system. The data received in the master can be visualised there or further processed for control purposes. In restricted volume, signal conditioning instrument-specific parameters can be outputted, modified and returned again.

Via the PC interface on the front of VEGACOM 557, the VEGA visualisation software "Visual VEGA“ or the VEGA configuration software "VEGA Visual Operating“ (VVO) can be operated. For these applications, the coupling between VEGACOM 557 and a PC is made directly with the connection cable between the RS 232 interface (PC) on the front of VEGACOM 557 and a standard Port (e.g. COM1) of your PC. There is also the possibility to provide a connection via modems.

1.2 Configuration

The component VEGACOM 557 is designed in 19" technology with 5 TE width (1 TE = 5.08 mm) acc. to DIN 41 494. It can be used:

- in carrier BGT 596

- in VEGALOG 571 carrier BGT LOG 571

- in housing type 505.

The electrical connection of supply voltage, DISBUS and Modbus is made via a plug connection acc. to DIN 41 612 on the rear of the component. The connection to LOGBUS is made via an additional 5-pole plug-connector mounted to the DIN-socket.

A 9-pole SUB-D plug marked “PC” is located on the front panel of VEGACOM 557. It is used for connection of a PC via RS 232C to VEGACOM 557.

Basic board

1.3 Functions

The VEGACOM 557 interface converter can be integrated into the VEGA level or pressure measuring system in two different ways:

either

- as DISBUS participant or

- as LOGBUS participant.

In both cases, VEGACOM 557 operates as passive participant and provides measured data and status information of the connected VEGA signal conditioning instruments via the external system. Through the use of readable text, a connection with simple terminal programs is possible.

Alternatively, it is possible to connect a PC with VEGA adjustment software via the SUBD-plug marked “PC” on the front panel of VEGACOM 557. VEGA adjustment software is actually available as two different Windows applications.

VVO = VEGA Visual Operating

For configuration and parameter adjustment of the connected VEGAMET or VEGALOG processing systems

VV = Visual VEGA

For visualising and recording of measured values of complete (multiple) vessel installations.

VEGACOM 557 on DISBUS

VEGAMET series 500/600 signal conditioning instruments transmit via the DISBUS cyclically measured data and status information, so called PC/DCS telegrams. VEGACOM 557 receives these data as participant on the DISBUS and makes them available (in buffer memory) for collection via the VEGA ASCII protocol.

If a PC is connected to the PC interface (front interface) of VEGACOM 557, this instrument transfers acyclically (on request by the VEGA configuration software VVO) measurement loop parameters from or to VEGAMET.

Max. two VEGACOM 557 can be connected to the same DISBUS. For clear identification, a different instrument address should be assigned to each instrument.

VEGACOM 557 on LOGBUS

Data are exchanged continuously on the LOGBUS between the individual components of VEGALOG 571. VEGACOM 557 receives as participant of this LOGBUS PC/DCS telegrams including the measured values and status information and makes them available (in buffer memory) for collection via the VEGA ASCII protocol.

Product description

VEGACOM 557 with VEGA ASCII

The data communication between VEGACOM 557 and a master is only carried out if initiated by the master, which can enquire the requested information by means of special commands.

The data from DISBUS/LOGBUS are first written in a buffer memory of VEGACOM 557. The data set is transferred from this buffer memory into a process image. The protocol conversion software enquires the stored data cyclically from the individual storage areas.

The data sets are checked and converted into the VEGA ASCII data format. After the conversion, the data are transferred into the emission memory and are sent from there to the master.

Direct connection

As an alternative to the VEGA ASCII communication, a PC can be connected via the PC interface (SUB-D-plug in the front panel of VEGACOM 557). By means of the adjustment and indicating software VEGA Visual Operating (VVO), the parameter adjustment can be made on the signal conditioning instruments

connected to VEGACOM 557. The adjustment concept includes the user-friendly configuration and parameter adjustment of the measuring system or the sensor with the following instruments:

- VEGAMET series 500/600 signal conditioning instruments

- VEGALOG 571 processing system

- VBUS ultrasonic/radar sensors.

The adjustment is menu-driven and window orientated. No matter if a radar sensor, several connected signal conditioning instruments or a VEGALOG should be adjusted via the PC, the procedure is always the same. As another possibility, measured values and fault signals of the entire processing facility can be recorded and shown graphically by means of the visualisation software VISUAL VEGA (VV). Tools for processing and analysis of history data are also available.

The configuration of the measurement loop comprises, depending on the connected instruments, e.g. the determination of output functions or the configuration of individual outputs or inputs. The user-orientated editing of measurement loops is supported by graphic means, such as e.g. vessel drawings and pictographs that adapt to the selected general conditions and options. Thanks to the graphical support, even more complex parameter adjustments such as e.g. the input of a linearisation curve by means of index markers can be done with ease.

Connection via modem

The PC interface supports, beside the direct connection of a PC, also the operation via modems. With this additional function, remote parameter adjustment or remote diagnostics of VEGA systems via VVO are possible. Together with the visualisation software Visual VEGA, even remote visualisations can be carried out.

The module position is individually selectable. Please note that the two connected modules cover a width of 10 TE (5 TE for VEGACOM 557 plus 5 TE for the adapter board VEGACOM 557AP).

Connection VEGACOM 557AP

BGT LOG 571

With the bus board (part of the carrier BGT LOG 571) connection to LOGBUS is made automatically when inserting VEGACOM 557.

The voltage supply of the card must be provided separately. For this reason, a 2-pole terminal with tension spring connection, called U print. The permissible operating voltage of VEGACOM 557 should be observed. In case of DC voltage supply, the correct polarity should be noted!

BGT 596

When operating VEGACOM 557 as DISBUS participant, the DISBUS must be wired in addition to the supply voltage.

For the two cables of the DISBUS, a 2-pole terminal with tension spring connection is available. Make sure that the polarity is correct!

Switch settings on VEGACOM 557

For adjustment of the interfaces or the BUS parameters of the PC interface and the VEGA ASCII interfaces, various DIL switches are provided on VEGACOM 557. Before inserting VEGACOM 557 into the carrier or the housing, the DIL switches must be set according to the user-specific data. The data of these settings will be effective with the next initialization (switching on of voltage).

3.1 Adjustment of the PC interface

For adjustment of the RS 232 PC interface in the front panel of VEGACOM 557, a 6-pole DIL switch block is located on the basic board. The PC interface is used for communication between a PC and VEGACOM 557, by means of the adjustment software VVO or the visualisation software VV.

Instrument number

Only relevant when operating two VEGACOM 557 on the same DISBUS. If two VEGACOM 557 are operated on the DISBUS, different instrument numbers have to be assigned. Not relevant for operation on LOGBUS.

Automatic modem initialization

In position "ON“ the modem will be initialized automatically when connecting it to the VEGACOM interface.

Transmission rate

For VVO or VV, the transmission rate must be set to 9600 baud.
