A VEGALOG 571 processing system consists of a CPU, one
or several peripheral cards as well as a power supply unit
which are inserted into the 19" carrier BGT LOG 571. CPU and
peripheral card are designed as module cards in European
size (DIN 41494) with 5 TE width (25.4 mm). The supply
voltage of the cards with 24 V DC is provided e.g. via a power
supply unit VEGASTAB 593. The carrier with a width of 84 TE
and a height of 3 HE corresponds to the 19" standard format,
however, has an integrated LOGBUS board for communication
among the cards.
The maximum configuration of a VEGALOG consists of two
carriers mounted above one another with one CPU, 31
peripheral cards and one power supply unit. With this
configuration, up to 255 measurement loops can be set up.
3.2 Principle of operation
VEGALOG 571 is a modular processing system for a wide
range of applications, e.g. for level, process pressure and
differential pressure measurement.
To suit the application and the individual requirements,
VEGALOG 571 is put together using several module cards. A
CPU card and different input/output cards are available which
are inserted into a 19" carrier.
To suit these applications, VEGALOG 571 powers the
connected sensors and processes their analogue/digital
measuring signals or switching commands. The peripheral
cards take over the power supply as well as the processing of
the measuring signals. The processing is carried out in the
CPU through a special software consisting of function
