DAQFactory can easily do different things depending on the state of your system or anything else. The if/else/endif statements provide the mechanism for this:
if (Input[0] > 5)
do something when the latest value of Input is greater than 5
else
do something when the latest value of Input is less than or equal to 5
endif
The else is actually optional. You can of course put multiple steps inside the if:
if (Input[0] > 5)
Output = 3
AnotherOut = 2
endif
You can also nest ifs inside of one another:
if (Input[0] > 5)
if (AnotherInput[0] > 3)
Output = 3
else
Output = 2
endif
AnotherOut = 2
endif
For that matter, you can nest while and for loops or other block structures inside of each other. Just make sure everything lines up correctly:
OK:
if (Input[0] > 5)
for (Private.Count = 0, Private.Count < 10, Private.Count++)
Output = Private.Count
endfor
endif
NO:
if (Input[0] > 5)
for (Private.Count = 0, Private.Count < 10, Private.Count++)
Output = Private.Count
endif
endfor
