Hello @Fscu.1​ ,

You will find some examples on GitHub:

You can refer to Reference Manual RM0377 - "24.5.8 Modbus communication using USART". It highlight that the control part of the protocol (address recognition, block integrity control and command interpretation) must be implemented in software.
