I would like to use a converter from another manufacturer instead of Siemens' PM to convert 230Vac/24Vdc. What are the disadvantages of using converters from other manufacturers?

There are no disadvantages...The CPU will power the backbus and the external power can be used to power output modules. https://support.industry.siemens.com/cs/ww/en/view/73191930 also check this info: https://support.industry.siemens.com/cs/us/en/view/96998532
