Basic Design Flow Strategies Involving Modes and File Close

[Paul J S]

I am taking over a pre-exsisting Labview  (ver 7.1) project which was gone through probably never rigidly structures from the get go. I have a two queastions queastions.

1.) Queastion1:  I'm trying to introduce more structure in the code as per written requirments we have involving software flow in terms of  state transition between modes. Depending on what mode you're in specific functionalty or behaviors are allowed. None of this strict controlhas been implemented yet. The basic structure of the current program consist of Tack Seqeunce Structure as the highest outter level followed by a nested while loop and a mix bag of cases, while llops and stack sequence within the inner nested while loop.

Sound like a mess. Well, you can either patch it, or rewrite it from scratch, or walk away. Are you under the gun? In other words, are you being asked to do this in about 3 days when it would take a non-Greek god about 3 weeks to do? Your best bet is to implement a state machine. The state machine will allow you to decide which state to go to based on certain events, and allow you to ignore events if you're in a particular state. You can create a state machine using the template that ships with LabVIEW.

1.) Queastion1:  I'm trying to introduce more structure in the code as per written requirments involving software flow in terms of  state transition between modes. There are a total of six (6) modes defined and depending on what mode you're in specific functionalty or behaviors are allowed. None of this strict controlhas been implemented yet. The basic structure of the current program consist of Tack Seqeunce Structure as the highest outter level followed by a nested while loop and a mix bag of cases, while llops and stack sequence within the inner nested while loop.

My objective is to at the launch of the program initilize some variable or data object representing the current mode state and resigned the this data object as the modes changes as a way of tracking the current mode. I also plan to use this mode state to enable, disable or trigger other functions within the program. What is the best data type or mechanism to use? I was thinking about using some sort of enum object.     

2.) Queastion 2:

We have a Close File function at the outter while loop. We are able to close file after hitting a button but not able to read file with another utility application untill we actually exit the Labview program.  We can see the number of bytes being updated in the file listing in Windows XP but Labview not releasing file until we exit.

          a.) How do fix this?
