Why are you using an express vi for everything? What type of data are you trying to read in real time? why are you using a configure formula when you just want to add 4 values? you can use a compound arithmetic right?

i do not have the real time values right now. so i am juz trying to generate values and check if they can be read so that later i can use them with real time data. and i have used the formula node since later i might have to perform some other operations on those values.

your answer is not at all specific. You are not clearly explaining from where you want to read the data or the data format

i will be reading values from current, voltage sensors. i might have to write out those values onto a file and read the file later and perform some operations on it. the data i read from sensors will be continuously varying...

and since i don not have the real time set up ready now i want to know how to read from a file.. that s why i am generating some data and trying to read from it..
