Sets FC 300 analog output.
OUTDA n v
n = output number (42)
v = value (0 – 100000)
NB!:
Parameter 6-50 must be set to "MCO controlled".
With the OUTDA command it is possible to control the analog output of the FC 300
control card. FC 300 has one analog output. It is configured via parameter 6-50.
A FC 300 control card output can only be controlled from the application program
when it is configured as option output in the appropriate parameter.

Pseudo array for direct access to the field bus data area
PCD[n]
n = index
You can directly access the field bus data area with the command PCD without an
additional command COMOPTGET or COMOPTSEND. The communications memory is
written or read word by word (16-Bit).
NB!:
The parameters 9-15 and 9-16 must additionally to be set with the correct values.
