If Digital I/O 4 is configured as an output ( Digital Input/Output 4 Direction ( S.04.021 )), writing to this
parameter will set the state of Digital I/O 4. Setting to 0 will place the output low and setting to 1 will
place the output high.
#
Bitmapped parameter that can be used to set Digital I/O 4 Digital Output 5. This parameter is
effectively a combination of

( S.04.011 ).
Setting this parameter to 0 will configure Digital I/O 4 as an input. Setting it to 1 will configure it as
an output.
