What Im trying to accomplish is this: I have a PI ProcessBook Add on and it runs a trend continuously. In excell I want to be able to type in A1 a time and get A2 to imput the exact number data that was shwing in PI at that specific time. for example lets say I type in A1 11:32:00 PI's time formula is written in 24hr mode and with H:M:S. Ive tried this using the archived value under the PI add on many different ways with no sucess. Has anyone been able to achieve this or point me to a thread that has more info on this. Thanks.
