Performing Dynamic Digital Output Operations
Note:
This feature is accessible using the DataAcq SDK. It is not supported in the DT-Open
Layers for .NET Class Library.
Using software, you can enable a synchronous dynamic digital output operation for the
analog input subsystem. This feature is particularly useful when you want to synchronize and
control external equipment.
One dynamic digital output line is accessible through hardware. This line is set to a value of 0
on power up; a reset does not affect the value of the dynamic digital output line. Note that this
line is provided in addition to the other 16 digital output lines; see
information about the digital I/O features.
You specify the value (0 or 1) to write from the dynamic digital output line using the analog
input channel list. A value of 0 indicates a low-level signal; a value of 1 indicates a high-level
signal.
As each entry in the channel list is read, the corresponding value is output to the dynamic
digital output line. For example, assume that dynamic digital output operations are enabled;
that the channel list contains analog input channels 0, 1, 2, and 3; and that the channel list
contains the dynamic digital output values 1, 0, 0, 1.
shows this configuration.
Figure 29: Example Using Dynamic Digital Outputs
As analog input channel 0 is read, a high-level signal is output to the dynamic digital output
line. As analog input channels 1 and 2 are read, a low-level signal is output to the dynamic
digital output line. As analog input channel 3 is read, a high-level signal is output to the
dynamic digital output line.
