Yes, it's possible:

SCL:
DB3.DBW[variable]:= 2;

AWL:
AUF DB3
L 2
T DBW[#variable]

• 16 bit number (counter, timer, Fc, Fb, DB)
• 32 bit number as area internal-external pointer ((PIW. PQW, I, Q, global data, merker,....)
  

• it is intended as an area INTERNAL pointer(because then you specify the DBW memory area)
• it should be SLW 3 SLD3 each time it is loaded directly a new DWORD value,
• or directly loaded as a pointer ( L P#0.0 //area internal pointer; T #variable]
