Previous (non-PVSS) Data-Point Concepts

• Data-points rigidly organised in
  one- dimensional lists
• Every process variable is a single data-point
• Individual groups of components divided up
  into a number of data-points

Datapoint configs
Global value range of a DP variable. A value
must always be within the PVSS value range to be
valid. Individual value range can be defined for
each user Alert ranges can be defined where
parameters can be set for alarm handling. If a
value is invalid, a default value can be set in
various ways. PVSS supports either PVSS system
time or periphery-source time e.g. from PLC
(PROGRAMABLE LOGICAL CONTROL) for time
sorting. Parameters can be set for a number of
smoothing algoriths (time- or value-oriented,
edge-dependent, ...) thereby reducing work needed
for communication and the amount of data.

Datapoint configs
connects a PVSS data-point variable with the
periphery. How a peripheral address looks depends
on the driver. a mathematical function, that is
spontanously recalculated if values change plus
statistical functions for calculating average
values, minimum values, maximum values, etc.
