6.5.4.16 MC_ReadDigitalOutput_ISD51x
This function block provides the value of the digital
output. It is not guaranteed that short pulses on the digital
signal can be seen on the function block.
The output data is available immediately.

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 congured accordingly (see chapter 7.21.5 Parameter
52-05: Digital Output Conguration (0x2FFF)).
