Modbus and KNX variables list

I cannot find a list of variables available on CoolmasterNet from Modbus and from KNX.
I need list of variables for both internal and external units.

I see on CoolmasterNet brochure as optional feature "External unit diagnosys". What does it mean?

Thank you
Best regards

with Coolmasternet is not possible to read extarnal unit status, for example if there is a fault or something like that?

Usually final customers, such as house owner, have nothing to do with these parameters.
But Coolmasternet is also sold to interface large building units. In these cases SCADA / HMI developer would like to access every parameter available.

If it is possibile to retrieve those values it could be nice.
