8.2 Inventory enquiry/VMI via WEB-VV
A supplier would like to keep track of the tank stock levels of his
customers and replenish them on his own whenever necessary. Via a
display that is updated several times daily, he has access to the level
data of the previous days or weeks. The supplier can thus assess the
requirements/consumption of his customers and plan his deliveries
accordingly. This allows him to do anticipatory purchasing and also
better utilize the capacity of his truck fleet. In addition, a message
should be sent if the level in any tank falls below a certain predefined
minimum value. Using this method, the supplier can always guaran-
tee his customers a sufficient supply of raw materials for production
without their having to bother with purchasing and ordering. And he
has the added benefit of long-term customer retention and continu-
ous orders.

signal conditioning instrument to the central WEB-VV server at VEGA.
As an alternative, the measured value transmission can be also car-
ried out via the Ethernet interface and the existing company network.
The measured values can now be retrieved worldwide quickly and
easily by any number of (authorized) persons via Internet and web
browser. The current measured values as well as the history data are
