Processing
parameter block
For this block the parameters are:
–
Scaling
,
–
Filter type
,
–
Rounding
,
To enter the scaling menu press the button next to the
Scaling
label. The menu has the
following options:
a)
disabled
– no scaling of the input data,
b)
linear
– after choosing this option, the following parameter appears:
•
Configure scaling
– the submenu which allows the user to change the unit
in this logical channel and rescale the value using two points. This submenu
contains the following options:
◦
Input unit
– read only parameter, it displays the unit of the logical
channel source,
◦
Output unit
– the unit of rescaled data,
◦
Point 1
block contains the following options:
–
Input value
– value of point 1 before scaling,
–
Output value
– value of point 1 after scaling,
◦
Point 2
block contains the following options:
–
Input value
– value of point 2 before scaling,
–
Output value
– value of point 2 after scaling,
In MultiCon, linear scaling can be performed with the table placed below, but the slope and
offset are constant values and they should be determined by the user earlier.

Tab.7.2 The way to calculate the output value
Example:
The task is to rescale temperature from Centigrades, in which all of the MultiCon hardware
configurations are scaled, to the degrees of Fahrenheit. The formula which should be used for
this task is shown below:
where:
T
F
– temperature in the degrees of Fahrenheit,
T
C
– temperature in Centigrades,
9/5 – slope,
32 – offset,
