Reading memory Logo Siemens

Hi all
I have a variable in logo siemens (which is a temperature setpoint , could be positive or negative). This variable is located in VW37 in logo memory


So, I want to get this information using node red (raspberry pi), I declared and mapped the variable in this way : DB1,DWORD37

What I want is to get the value , for the other variables I don't have problems. I think is due to this variable has a negative value. In the graphic you could see the red circle (bad information) and green (good information)

Are you sure that vw37 is correct address definition? Word/dword variables should start with even numbers. Is it possible to change it?
