Function Switch an analog value depending on a digital value.
For example:
If XD1 = 1, set output Y to X2.
If XD1 = 0, set output Y to X3.
Formula Y = X2, if XD1 = 1.
Y = X3, if XD1 = 0.
Inputs One digital input (XD1).
Two analog inputs (X2 and X3).
You can enter the two analog inputs as parameters (engineering unit index number
and value for each parameter).
Output One analog output (Y).
None.
P3 X2 if X2 is not connected with a point.
P4 X3 if X3 is not connected with a point. If X2 is connected with a point, X3 is
numbered parameter 4.
Example See the Examples chapter in this manual for applications that use the SWI control
icon.
Also see the Digital Conversion note in the Mathematical Editor (MAT) section. You
can use SWI to convert a digital point to analog values for use in a mathematical
formula.
