The Concurent Real-Time CP-DA3218 and CP-DA0818 are 32-channel and 8-channel analog output boards, respectively. These boards feature 18 bit resolution and can be ordered in single ended or differential configuration. They support the following programmable voltage ranges: -10V to +10V, -5V to +5V, -2.5V to +2.5V, 0V to 10V and 0V to 10V.

Selects the units of raw values as being either Count or Volt. This is the unit used to store the raw value in the SimWB RTDB for the mapped item.
When Volt is selected, the voltage read from the board is stored as the raw value in the RTDB. If the variables mapped to hardware channels are defined with an associated engineering conversion, you must define the conversion to convert from volt to engineering unit. Without engineering conversion, the item value and raw value in the RTDB will be the same and expressed in volts.
When Count is selected, the unsigned 18-bit integer value read from the board is stored as the raw value. If the mapped RTDB variables are defined with an associated engineering conversion, you must take into account that the raw value range of 0 to 0x3FFFF corresponds to the board hardware voltage range. I.e. if you selected the voltage range to be -10V to +10V , 0 count will correspond to -10V and 0xr3FFFFF will correspond to +10V output by the board.
Channel number.
Input point(s) a channel is mapped to.
To map a point to a channel, select a channel on the left side of the I/O Mappings form, then click on a check box for an I/O point on the right side of the form. See I/O Mappings... for details.
The analog output process writes the 32/8 output channels on a single CP-DA3218/CP-DA0818 hardware board. One instance of this process is run for each board configured in the RTDB.
