Creating a Look up Table

[Richard@Loughborough]

Hiya,

I'm trying to create a VI which will look up the price of electricity for a given period of time.

I'm have a table which gives the price of electricity for given time periods, e.g:

Time Period          Price

12:00 - 12:30        6.8

12:30 - 13:00        7

13:00 - 13:30        10

and i want to be able to see what the price of electricity is at the current time - so if it is 12:15 the VI will tell me that the price is 6.8 and when it is 13:01 the price will change to 10.

Any suggestions?

some queries

Would the user enter the time in any specified format??

Or do you want the vi to read the system's current time and give the corresponding price??

i want to read the systems current time

Here is one method ( rather unelegant, I must confess )

Look at attached vi

Hi,

  a more mathematical approach that doesn't use the case statement.

You didn't say which version of LabVIEW you were using, so this is in version 7.1

Hope that helps

Thanks
