Smart Analog
Max
The maximum value over the last Smart Analog log
interval.
Units
The units of the Smart Analog. The SC300 takes the
units from the first analog input mapped to this
Smart Analog
for Addition and Average. For
Multiplication, units are kilowatts.
► To configure a Smart Analog
1
Create an entry in the Smart Analogs table for each sum, product or average value to be
calculated.
2
For each of the analog input values to be added, multiplied or averaged, create an entry in the
Analog inputs table and set
Function
=
Smart Analog.
Set
Index
=
Smart Analog
number as
above.
All the Analog inputs mapped to the same Smart Analog are then added, multiplied or
averaged according to the
Type
setting.
3
For each of the system values to be added, multiplied or averaged, create an entry in the
System Values Mapping table.
In the Analog Inputs table, more than one analog input table entry can be mapped to the same
physical input. This allows you to create an entry to map an input to a Smart Analog, even if it is
already used for another Function.
To subtract an analog value, create an entry in the Analog Input table with a negative gain. This
will make the value negative, so it will be subtracted from the other positive value(s).

Configure the Smart Analog values as below:
Parameter
Description
Name
Type the name of the
Smart Analog
.
Function
Maps a Smart Analog to a particular function.
e.g. Set to
Smart Analog
to use this value as an input to another
Smart analog.
Set to Load Current to use this Smart Analog value as the system
load current value.
Func Index
In some cases, an index will apply to the Function.
e.g. Smart Analog requires an index.
Type
Set to:
•
Average to average them
•
Addition to add all the analog inputs mapped to this
Smart
Analog
•
Multiplication to multiply them together.
•
kMultiplication to multiply them together and multiply by
1000.
Useful for instance where output is to be in kW
•
Max to set the Smart Analog to the maximum input
•
Min to set the Smart Analog to the minimum input
