Data
Accessibility
Although excellent facilities exist for
the display of data within AWAX, some engineers like the
ability to export data to a spreadsheet or comma separated
text file. AWAX can transfer live data to a Windows standard
spreadsheet, giving on line access to either the current value
or a trend history of multiple inputs. CSV files can be
created either automatically or as directed by the user. For
example the user can spool off data to a removable floppy disk
on a week by week basis, this data can then be re-imported
into AWAX at a later date and then re-displayed by AWAX
graphics without affecting current data
collection. |

Archiving/Trending
Although the current value of
a system input is very important, a historical representation
of the data point in the form of trend data is also important.
AWAX keeps a running history of system inputs up to a user
specified data limit. These historical values can be graphed
using a powerful graphics/trending package which includes
multi-level zooming, forwards and backwards scrolling and fast
forwards/reverse. Up to 24 graphs at any one time can be
viewed on screen. The graph formats can be stored so that upon
entering AWAX, the system will open up at a user configured
format. |

Supervisory Control
Where control is required
AWAX has very powerful facilities for the control of plant and
equipment in the form of 'sequences'. These are on-line user
definable mini-programs which provide a wealth of control
possibilities. Sequences can be initiated from on screen
buttons, the system menu or as a result of a changing system
input. For example, a a sequence could be created to perform a
complex plant shut down operation all from one press of a
button. Since sequences can be edited and compiled on-line
they are simple to create and modify and they can also be used
to request operator input , display schematics, check inhibits
before any control operation, in fact there is very little
that one cannot do with an AWAX sequence. |

Alarms
Handling
AWAX has multiple alarm limits per system
input and hysteresis capabilities reducing the risk of 'ghost
alarms'. Limit messages and digital state changes can be
routed to alarm and event lists as well as to printers, hard
disk files, communication ports and/or pop up message boxes.
The system is capable of multiple alarm and/or event list
entries can be accepted and/or deleted by the operator. Alarms
can also be used to generate pre-recorded audio messages via
burst mode. |

Calculation Package
AWAX provides facilities for
complex math's operations which can be evaluated regularly or
triggered from an event. For example, a pseudo variable could
be treated to represent the volume of liquid through a pipe
during the day given the flow. From that point on the
resulting derived analogue is treated as an ordinary analogue
value. |
