    Good afternoon,
    I need to call into 'Global variables' the variables defined into 'service data object' (in the picture1).

    How can I define them? And, how can I see the address I have to use?

    Sonda1 AT %IW??? :WORD;

    Thank you

    Hi
    normally you would need to use the Function block SDO_Read in the CIA405 library. The library is added along with
    the can device.

    Thank you for the response.
    So basically I have to put inside my PLC_PRG a function that can read that address correct?

    Something as:

    test:= := CIA405.SDO_READ4(x,x,x,x,x,x,x,x,x,x,x,x);

    Correct?
