Digital
On for the specified duration after the soft key is
pressed, otherwise off. Off when the pulse is canceled by
a second key press.
Name
Uniquely identify this FB using up to 20 alphanumeric characters.
Function
To configure the key to produce a pulse of a specified duration when it is pressed, set Func-
tion to On Pulse.
Time
Set the length of time the output should remain on after the key is pressed.
Range: 0 to 99,999 seconds
Linearization
Use a linearize block to scale an analog signal according to a 10-point scaling curve and an
offset. This block is found in the Function Block Diagram editor’s Library when working with
a data logger that offers the Linearize block. Within the Library, the number of these blocks
available is shown in parenthesis.
Choose the type of scaling curve with the Function parameter. These options for the Function
parameter are described in detail in the following sections:
: The output is equal to the input plus the offset.
: The output is equal to the scaled input plus the offset. The scaling curve is com-
posed of line-segments connecting ten points. The output changes gradually as the input in-
creases or decreases.
: The output is equal to the scaled input plus the offset. The scaling curve is com-
posed of horizontal line segments extending from each point connected vertically to the sub-
sequent point. The output is constant as the input increases until the input reaches the next
step at which point the output changes abruptly to the new value.
Off
When the Linearize block’s function is set to Off, the output is off.
