SUMMARY
Measuring Points are information carrier having specific properties.Measuring Points are analog or binary.
CONTENTS
Introduction
Measuring Points may be combined in Lists with other DataObjects. There are
two types of MPs: analog and binary.
The _MP .dbf tables in Vision NT are different to that in AvET, they deviate
in Event-Registration :
The Status definitions assigned to a MP are edited in a separate window below
the DataObject List.
