how Labview is usefull in Industrial Automation what is the diffrence between Siemens sematic 7 software and Labview

[Hooovahh]

Your question is worded in a ridiculous way but I will do my best to answer it.

LabVIEW is a programming language.  It runs on many platforms and has lots of support for any test application but is not limited to just testing environments.

Siemens Simatic 7 appears to be a scripting language written to work with Siemens PLCs.
