Product description 1 Product description 1.1 Application 1.2 Configuration 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 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.
Product description 1.3 Functions The VEGACOM 557 interface converter can be integrated into the VEGA level or pressure measuring system in two different ways: VEGAMET DISBUS % 100 + - ESC OK CONNECT ! on VEGAMET 513 either - as DISBUS participant or - as LOGBUS participant. VEGACOM 557 PC BA ! on 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.
Product description 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. VEGACOM 557 on LOGBUS Data are exchanged continuously on the LOGBUS between the individual components of VEGALOG 571.
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.

Mounting and electrical connection 2 Mounting and electrical connection 2.1 Mounting instructions The gateway VEGACOM 557 can process measured data and status information in two different ways: - via DISBUS (from measuring systems with VEGAMET) - via LOGBUS (from measuring systems with VEGALOG). Instrument coding Function coding VEGACOM 557 a27 c3/c11 Instrument coding Function coding d b z a c 1 For DISBUS configurations, VEGACOM 557 can be either mounted into carrier BGT 596 or housing type 505.
Mounting and electrical connection 2.2 Mounting in carrier and housing 2.3 Wiring plan VEGACOM 557 BGT 596 or BGT LOG 571 PC interface in front panel (SUB-Dplug) For mounting, a slot module must be provided at the location. A slot 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. The multipoint connector is available in the following versions: - Wire-Wrap, standard connection 1.0 mm x 1.
Mounting and electrical connection Connection via modem For remote parameter adjustment, it is possible to connect the PC interface via a modem. In such a case, the modem cable that comes with the respective modem should be used. Modem operation is supported by VEGACOM 557 from software version 2.11. Further information on the remote parameter adjustment is stated in the operating instructions "Remote parameter adjustment“.
Mounting and electrical connection Modbus via TTY Supply voltage d b z + – 2.4 Mounting and installation instructions with VEGACOM 557AP As an option, VEGACOM 557 can be extended with the adapter print VEGACOM 557AP. The adapter print VEGACOM 557AP consists of a module card with 5 TE width and two modules connected to a back-panel print for carrier BGT 596 or BGT LOG 571.
Mounting and electrical connection Make sure that also VEGACOM 557 is set to the same interface type (DIL-switch 1 on the additional board) as VEGACOM 557AP. The pin assignments of SUB-D-plug and SUB-Dsocket is listed in the tables. Pin assignments VEGACOM 557AP Pin-Nr.

Data image in VEGACOM 557 4 Data image in VEGACOM 557 VEGACOM 557 collects the measured values of the VEGA signal conditioning instruments VEGAMET 509, 512, 513, 514, 515 and 614 (via DISBUS) or VEGALOG 571 (via LOGBUS) and puts them in the temporary memory for collection via the VEGA ASCII. Due to these two different series, it is necessary to use two different telegrams for the enquiry of measured values. With enquiry "P“ 3 values are transmitted.
