You can use DIP switch to set PROFIBUS address. Cut-off and recycle the power of SM277B module to make them effective after you change the address.
DIP switch SW1-8 (in binary), SW1 for the LSB, SW8 for the MSB (must be "OFF"), SW1-SW7 set as "ON" - "1", "OFF" - "0", calculated as following:
Address =SW1×20+ SW2×21 +SW3×22 +SW4×23+ SW5×24 +SW6×25 +SW7×26
