start script automatically

[Tom]

Hi,

I have a problem because I don't know how to start my script 
automatically after a special event happens.

In detail: I store data from a PLC. Every 30 seconds the data is stored 
in a new file. After the file is stored I would like to start my script 
that analyzes the data right away. Any help how to do this is deeply 
appreciated.

Thank you very much in advance.
Regards, Tom
