Analogue IO Collection (& Memory)
The
Analogue IO Collection objects in the ROT
control which analogue IO are made available to the system.
Once
the IO have been added to the system this object will typically be
dragged onto tool inputs pages to give them access to analogue hardware
and memory.
Using the Analogue IO Collection
Right-click the
AnalogueIOCollection in the ROT and choose "Edit". On
the Analogue IO
tab the IO Type
dropdown menu will display a list of all the analogue
IO installed
in the system. Even though this dropdown list represents the installed
IO, they will not be made available to the tools in Automation Manager
until they are added to the system. Select an IO and type a name in the
Name text
box, then click the
"+" button to add it to the system. When the "+" button is
pressed it will appear in the list in the Analogue IO tab.
The
order of the IO in the list may be important for some applications.
To change the placement of an IO click on it to select it,
then
use the "^" and "~" buttons to move that IO up and down in the list.
Use the "X" button to remove an IO from the list.
Using
the Analogue IO Memory
The
Analogue IO Memory object works exactly like the Collection object,
except it is specifically designed for memory analogue IO. If
a
memory IO needs to be added to the system it should be done through the
Analogue IO Memory object in the ROT and not the Analogue IO Collection
object.
Types of Analogue IO Memory
AnalogueInputRandom
will produce random readings.
AnalogueInputTime
will produce a reading that increases consistently according to
standard time measurements.
AnalogueIOCombine
will combine the readings from the first two analogue IO.
AnalogueIOFluidAverage
will apply averaging to the first analogue IO. The amount of
averaging can be set by right-clicking the graph it produces in the
Analogue IO window and changing the "Number of Reads" on the "Fluid Avg" tab.
AnalogueIOMathFunction
will use a generate readings based on a sine wave, sine noise or by
counting up from zero. The function can be set by right-clicking
the graph it produces in the Analogue IO window and changing the
"Function" on the "Maths" tab. The "Maximum Raw Value" sets how
high the values will go.
