DAC internal device v. 2.6
INSTALLATION
Device declaration in the configuration file (.CNF)
In the configuration file (.CNF), the BUS section must be declared so that the hardware resources
to implement the DAC device are available. At least one 16 bit resolution analog output must be
available.
In the INTDEVICE section of the .CNF file, the following definition must be added:
;---------------------------------
; Internal device declaration
;---------------------------------
INTDEVICE
..
<device_name> DAC IOutA
where:
<
device_name
> Is the name of the device.
DAC
Is the key word that identifies the device analog output.
IOutA
Hardware address of the DAC component of the Slave analog
output.

Internal device declaration
;---------------------------------
INTDEVICE
OutAn DAC 2.AN01
The device DAC doesn’t
required any sampling time
declaration because its
output value is update only
writing on its in variable.
It is necessary than all the
shouting of definition are
restored on the same line
and in the same sequence.
The resources of the devi-
ce that are not used should
be marked from a X to the
place of their physical
address.
