The loop continues to work if you change it to
while True:

Sorry, Here my code in plaintext

break

As you can see your code is all messed up.
You need to post

Yes, although we are limited in scope to Python language
and standard library so for anything specific to openopc
you will probably need to ask on its support forum/list.

Hi,
I am almost new to python and I am trying to build a not so easy app (but
very neat and useful) related to industrial automation.
Is this the right place to knock down problems one by one?
Basically my app has several interactions but the most important is reading
values from an embedded machi
I hit the send button too early. anyway
Basically something like
while (stop condition false)
read data
write data into local array or something
wait sample time
Thanks
marco
