Re: how to inititial VAL field in motor record

Alex,

Initializing the VAL field of a motor record with soft-channel device support won't work.  The soft-channel device support for the motor record expects to get the motor's readback position from the PV in the RDBL field and it synchronizes the target position with the readback value at initialization.

The motor record documentation contains an example of how to use the motors with soft-channel device support:

Hi,

I am trying the initialize the motor record field(VAL, "1.6050") field, with field(PINI, "YES") and I am not having success.

    field(DTYP, "Soft Channel")
    field(PREC, "4")
    #field(DVAL, "1.6050")
    field(VAL, "1.6050")
     field(PINI, "YES")

}
