Profinet devices #77

Closed lpmwfx closed 4 years ago

lpmwfx commented 5 years ago

Can the lib be used for communication with Profinet devices as frequency convertsers and remote IO's like ET200 from Siemens?

ceremcem commented 5 years ago

Nearly impossible, AFAIK. Profinet and Profibus are proprietary protocols that requires an extensive reverse engineering effort.

lpmwfx commented 5 years ago

Yes I thought so. Even though it seems to be open it's not in reality. But is that also true if I use 3rd party devices like a ASI gateway from IFM - They gladly are going to reveal the internal adresses.

ceremcem commented 5 years ago

I don't know anything about the mentioned device, but any company can freely produce a proxy device. They can also mimic Profibus/net API for sure, which would give the impression of revealing the Profibus internals.
