VEGACOM 557 - without protocol 5
Product description
1.2 Functional principle
The gateway VEGACOM 557 can be inte-
grated in two ways in level or pressure meas-
uring systems:
- as DISBUS-participant
- as LOGBUS-participant.
In both cases it is a passive participant.
VEGACOM 557 as DISBUS-participant
VEGAMET series 500 /600 signal conditioning
instruments transmit so called PC/PLC-tel-
egrams via the DISBUS measured data and
status information. VEGACOM 557 receives
as participant on the DISBUS these data.
Max. two VEGACOM 557 can be connected
to the same DISBUS.

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 meas-
ured values and status information as a par-
ticipant of this LOGBUS.
