Bulletman

Thank you for all your answer. I'm going to look into all your solution. I'm unfamiliar with most of the termination that you use and therefore it might take a while before I understand all options! Thanks for all your help! @Ton: Don't worry....a chemical engineer addicted to the cheap energy drink "Bullit".....but bulletman sounds better

Dear All, My name is Dennis aka "bulletman". I'm a chemical engineer and at this moment I have an experimental setup that I would like to control with Labview. At this moment everything is done manually. The setup contains the following things: 3x Balances RS232 6x Mass Flow Controller, RS232 1x Mass Flow Reader, RS232 3x Temperature Control, RS232 2x ISCO pumps, RS232 2x Characterization machines, RS232 One week ago, I started to be interested in using labview and I did some online tutorials and played around in the programm itself. I think the program itself is not that hard to use, but I don't have any experiences with data acquisition so far. At this moment I'm not sure which kind of hardware I need for my purpose. If I understand correctly, I need a DAQ card which is connected to a box with multiple RS232 connections. By addressing the cards com port and the respective channel (every channel is anothere RS232 port?) it becomes possible to read/control the experiment? Please help me out! Next, Do you guys think it is duable (for an in-experienced person like me) to write a labview program that is able to control/read the MFC's, TC's, pumps etc. Thanks, Dennis
