array manipulation

[IBI]

Hi, i'm developing a program for sending signals (to a machine). First i want to analyse the signals i send with a dummy program. The dummy program consist of a send part, and a receive part. In that program i can compare both signals (send and receive signals). The problem is that by receiving the signals i do not get them in the right sequence. Could you please help me with this problem. I send the dummy program.

Hi, I took a look at your program, but the code is not very clear. I guess with input and output in you mean the AI one point and AO one point function calls. However they are running in parallel, so you cannot say which one goes first and which one goes second. You can use a sequence structure to make sure they run in the correct sequence. (now the AI one point can happen after the AO one point; place a sequence in the while loop and put the AI one point in the first frame). You can put your X-Y graph inside the while loop if you want to view the results on the fly. With realtime I suppose you mean, while gathering data and controlling the process you want to do a comparison. You can do the calculation inside your while loop.
