I/O Module Output
Block Input Data Type
Enter a vector of numbers between 1 and 4. This driver allows the selection of individual D/A channels in arbitrary order. The number of elements defines the number of D/A channels used. For example, to use the first and second analog output (D/A) channels, enter
Number the channels beginning with 1 even if this board manufacturer starts numbering the channels with 0.
From the list, choose a voltage range. The output range applies to all channels. This range must agree with jumper settings in block J13 on the board.
The reset vector controls the behavior of the channel at model
termination. Enter a scalar or a vector that is the same length as
the channel vector. If you specify a scalar value, that setting is
replicated over the channel vector. If you specify a value of
the corresponding channel is reset to the value specified in the initial
value vector. If you specify a value of
channel remains at the last value attained while the model was running.
The initial value vector contains the initial voltage values for the output channels. Enter a scalar or a vector that is the same length as the channel vector. If you specify a scalar value, that value is replicated as initial value over the channel vector. The channels are set to the initial values between the time the model is downloaded and the time it is started.
If you provide an out-of-range value for a channel, that value is adjusted to be within the range defined by the parameter Range.
Select this check box to display real-time error information.
This check box displays an output port labeled E. As long as the driver
does not detect an error on the channels currently in use, this signal
has a value of 0. Values of 1, 2, 4, 8, and so forth respectively
indicate problems on channels 1, 2, 3, 4, and so forth. To use one
signal to indicate errors on multiple channels, the driver combines
these values. For example, the
E value 1 + 2 =
3 encodes the concurrent errors on channels 1 and 2, the value 2 +
4 = 6 encodes the concurrent errors on channels 2 and 3, and so on.
Enter the base sample time or a multiple of the base sample
-1 means sample time is inherited).
Enter the base address of the board. This entry must correspond
to the DIP switch setting on the board. For example, if the DIP switch
setting is 300 (hexadecimal), enter
