SLC 5 analog input problem

[Mickey]

If your card is set for +-10V the unscaled data would range from -32768 (-10V) to +32767(+10V).

Only IF the OP has the data format set to proportional counts, then yes.

See pdf for other options. Post #5

Yeah, I went back and took a second look myself.

If the OP has it configured for "Class 1" then I believe your original statement would be correct. "Class 3" has all the configuration options.
Just to confuse the OP more.

So, if my analog input is set to engineering units, it will use the actual value?

In my 0 to 1 volt input, set to engineering units I would use a 0 minimum and 1 maximum input on the SCP?

No. Look at the table Mickey posted in post #5. At the bottom of the first page there is a table titled, "Channel Data Word Values for Engineering Units".

-10.25 to +10.25 volt would be scaled as -10,250 to +10,250

Therefore -10 to +10 volt would then be -10,000 to +10,000
So then 0 to +10 volt would be 0 to +10,000

Which means 0 to 1V would range 0 to +1000

Thanks for claifying.
Do most people use proportional inputs?

 

[Operaghost]

Can't say. I usually use it unless I am setting up a PID. Then I use the Scaled for PID setting.
