I have Siemens node in one of my projects that has communication module Siemens CM PtP (6ES7 137-6AA00-0BA0). I would like to use this module for serial communication RS422 with another device, but can't find any resources how to do it. Inside of CodeSys 3.5 project I have only 8 bytes of inputs in I/O mapping (for Wago 750-652 serial module I can choose 3 configuration until 48 bytes IN and 48 bytes OUT).
There are also other modules in this node that are working correctly, but this one is complete mystery.
Does anybody know how this module is used, or where to find documentation for it?

That might be the case. I will also try to ask on Siemens forum. It just makes bit more sense to ask on Codesys forum how to develop Codesys program...

you are not in the good place to ask support about siemens products.
btw, you could start with https://support.industry.siemens.com/cs/attachments/59057093/s71500_cm_ptp_function_manual_en-US_en-US.pdf?download=true
