6.5.4.17 DD_WriteDigitalOutput_ISD51x
This function block writes a value to the digital output of
the axis. If Enable is TRUE, the input Value is evaluated. If
the input Enable is FALSE, the last value is used. This
function block only works if the usage of the digital output
is configured accordingly (see chapter 7.21.5 Parameter
52-05: Digital Output Configuration (0x2FFF)).
