Sorry for delay with answer. On you screenshot you are not receive answer.
Please, try to change RX and TX wire on you connector.

Also, you carefully read readme file on the github, where you download this firmware?
Here copy of this text -

Software Implementation of PLC with STM32 "bluepill" hardware.

Version G34 -
For now you can use all 8000 steps in you program. This version not for field of industral use, and now you can use only 4 input and 4 output. Also you can use all posibility for master and slave modbus, but only 50 requests.
From this version modbus slave adress is fixed - 111 for UART1 and 112 for UART2.
Also you can program device from any port( not only USB VCP), connected as modbus slave.

Please, use modbus address 111 and 112. This can solve you problem.

With best regard, support team.
