Pfeiffer Omnicontrol 400 - communication

[Alex0404]

Hello,

I am trying to communicate to Pfeiffer Onmicontrol 400 unit with integrated power supply pack intended for control the electronic drive units of Pfeiffer Vacuum vacuum pumps. We aim at remote communication with the device. However, a response from the device comes in the form of so called Telegram frames (see an example in the picture attached). The question is whether Labview can translate the response from Telegram frames to ASCII or text or to any other form that can be recognized by NI Max? Or there is any open source software that could deal with it?

Thank you in advance, hope to find a solution.

It seem to use a non-standard command packets to communicate (AFAIK), but someone has created a Python library - https://github.com/electronsandstuff/py-pfeiffer-vacuum-protocol 

You may be able to use that python functions in LabVIEW to keep it simple or recreate the Python code in native LabVIEW.
