I have a problem with Python script for libnodave.
Currently I try to find a problem but I'm nor sure if script code is ok?

Here is my code:

import ctypes
import os

daveProtoPPI = 10 # PPI for S7 200
daveProtoAS511 = 20 # S5 programming port protocol
daveProtoS7online = 50 # use s7onlinx.dll ...
