Using Multiple Inputs to Control One DAC Output
Update Mode: Rising Edge, for each of 2 channels
Criteria Used: Inside Window, for each of 2 channels
The following figure shows how multiple inputs can be used to update one output. Here we are updating
the analog output of DAC1.
Analog input Channel 3 has an
inside-the-window
setpoint applied. Whenever C
hannel 3’s input goes
inside the programmed window, DAC1 will be updated with 3.0V.
Analog input Channel 7 also has an
inside-the-window
setpoint applied. Whenever C
hannel 7’s input goes
inside the programmed window, DAC1 will be updated with
minus
7.0V.

Using Two Criteria to Control an Output*
*
The update
on True Only
mode was selected and therefore the updates for DAC1 will only occur when the criteria is
met. However, in the above figure we see that there are 2 setpoints acting on one DAC. We can also see that the two
criteria can be met simultaneously. When both criteria are
True
at the same time, the DAC1 voltage will be associated
with the criteria that has been most recently met.
