Product description 1 Product description With VEGACOM 557 an efficient interface converter is available. It is used for conversion of the VEGA-specific DISBUS and LOGBUS-interface to a RS232C-standard interface. Due to this, measured data and status information of level and pressure measuring systems can be transferred to a PC and visualised there with Visual VEGA (VV).
Product description VEGACOM 557 as LOGBUS-participant There is a permanent data exchange on the LOGBUS between the individual components of the VEGALOG 571. The VEGACOM 557 receives PC/PLC-telegrams containing measured values and status information as a participant of this LOGBUS. 1.2 Functional principle The gateway VEGACOM 557 can be integrated in two ways in level or pressure measuring systems: - as DISBUS-participant - as LOGBUS-participant. In both cases it is a passive participant.
Adjustment 1.3 Function 2 Adjustment The data of DISBUS or LOGBUS are firstly written in VEGACOM 557 into a buffer memory. From this buffer memory the data are read out by means of the Visual VEGA (VV) visualisation software. The indicating elements of VEGACOM 557 are located in the front plate of the component. LEDs are used as indicating elements signalling the operating condition (see page 9).
Adjustment 2.1 Configuration and parameter adjustment of connected measuring systems An additional function of VEGACOM 557 is the adjustment of the connected measuring system. The adjustment is made via a PC by means of the VEGA Visual Operating (VVO) adjustment software . The PC is connected via an interlink cable to the 9-pole SUB-Dplug in the front plate of VEGACOM 557.

Mounting and installation 5 Mounting and installation 5.1 Mounting and connection instructions The gateway VEGACOM 557 can receive measured data and status information in two different ways: - via the DISBUS (from measuring systems with VEGAMET) - via the LOGBUS (from measuring systems with VEGALOG).
Mounting and installation 5.2 Mounting in carrier and housing BGT 596 or BGT LOG 571 For mounting you just have to place a module in the requested position. A module consists of: - a multipoint connector acc. to DIN 41 612, series F, 33-pole (d, b, z) - two screws - three coded pins - two guide rails.
Electrical connection 6 Electrical connection 6.1 Connection instructions Interface cable PC – VEGACOM You should please note the following instructions for electrical connection: - the connection must be made according to the appropriate national installation standards (e.g. in Germany acc. to the VDEregulations). - the voltage supply of VEGACOM 557 must be made with low voltage to keep protection class II. When using VEGASTAB 593-60 or 593 a reliable separation of mains circuits acc.
Parameter adjustment of the interface 7 Parameter adjustment of the interface DIL-switch basic board 7.1 Switch positions on VEGACOM 557 ON A 6-pole DIL-switch block for adjustment of the RS 232 PC-interface in the front plate is located on the basic board. EDG Factory setting 1 2 3 4 5 6 Data format 8 data bits, 1 stop bit, even parity 8 data bits, 1 stop bit, no parity Before inserting VEGACOM 557 in the carrier or the housing, the DIL-switches have to be adjusted to the user specific data.
Set-up 8 VVO or VV in conjunction with VEGACOM 557 The configuration, parameter adjustment and adjustment of VEGA processing systems can be made with VEGA Visual Operating (VVO). For the visualisation of measured values the Visual VEGA (VV) software is available. For the use of VVO or VV a PC is connected with the RS232C-interface of VEGACOM 557. When this connection is not directly made via a cable, but by means of a modem via a telephone net, this is called remote parameter adjustment.
Connection examples 10 Connection examples The following connections between PC and VEGACOM 557 are possible to enable access to a VEGA processing system from a PC with VVO or VV via a VEGACOM 557. • PC on the front interface • Modem on the front interface 10.1 PC on the front interface In this example a PC is connected via the front interface of VEGACOM 557 with the VEGA processing system. The front interface is a RS232 C interface. Procedure: 1.
