With the product we design we are able to communicate via RS-232 ports. What I'm trying to do is filter out the data that is given by multiple differnt types of products that will give similar data back, but in a differnt format. Such that in a status command I'm looking for everything to be in a non failed state. But some items will show warning, failure, #.##w(for warning), or #.##f (for fail). But the format of each product is different. Also for a meter command I'm looking for a way to filter out just the numeric value for each phase amplitude, but once again the format will be different for each product. I have been able to pull this data out easy enough for an individual product but not on a wide product range with the same VI.
