Product description

VEGACOM 557 on DISBUS

VEGAMET series 500/600 signal conditioning

instruments transmit via the DISBUS cycli-

cally 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) measure-

ment 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 tel-

egrams including the measured values and

status information 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) measure-

ment loop parameters from or to VEGALOG

571.

Max. two VEGACOM 557 can be connected

to the same LOGBUS. The addressing for

clear identification is made automatically on

LOGBUS.
