Hi,

I don't know what PLC is, but why not use an endless loop.
Files arrive in a directory called "input" and after processing
you move them to a directory called "done".

(not tested)
while 1:
    for file in os.listdir("input"):
        process(file)
        os.rename(os.path.join("input", file), os.path.join("done", file))
