The Module ID has two functions:

There are two approaches for mapping this block to a specific I/O module installed in your target machine. All modules of the same type must be configured using the same method.

Choose the active input/output channels by selecting the corresponding checkboxes. For each active channel, a separate row for the channel settings is displayed.

	Note
	Analog Input channels must be selected in consecutive order.

Select either Single-Ended or Differential. For single-ended channels, each output signal is referenced between the Analog Input line and the analog ground. For differential channels, the voltage is referenced between the Analog Input (+) line and the Analog Input (-) line. For more information, refer to the I/O pin mapping section.

Enables incoming data to be transferred over DMA. It also allows much higher system sampling rates to be achieved as the CPU does not have to process the data transfer. In addition, frame-based operation is possible, meaning that multiple samples can be received from the I/O module in one sample hit. If Enable DMA is active, the model or subsystem containing the Analog input block must be triggered with the I/O module DMA interrupt for consistent results. Refer to the usage notes for more information.

Parameter dependency is as follows: Frame Size = Sample Time × (ADC Rate / Active Channels). By defining two parameters, the system will determine the third parameter automatically when the third parameter is set to -1.

Example Frame Size equal to 1, Clock Divider equal to 6250, and Sample Time as -1. Sample Time is computed automatically to be 1 [ms].

Defines how many samples are transferred from the module at each sample hit. The output ports of every channel become a vector with the same number of values, where the value at position 1 is the first taken. Enter "-1" to allow the system to determine the Frame Size automatically.

During non-DMA operation, the Simulink model triggers each conversion, but during DMA operation, the hardware does this independently from the model and therefore needs a clock. The ADC Rate is calculated internally by dividing the base clock of the module (50 [MHz]) by the Clock Divider value. The ADC Rate defines the available frequencies. Enter "-1" to allow the system to determine the Clock Divider automatically.

Define the base sample time at which the Analog input block gets its sample hit. Enter "-1" to allow the system to determine the Analog input block Sample Time automatically.

Select the voltage range for the input channels. Single-ended: ±0.64 V, ±1.28 V, ±2.56 V, ±5.12 V or ±10.24 V. Differential: the same as the single-ended plus: ±20.48 V or ±24.576 V.

Choose the active input/output channels by selecting the corresponding checkboxes. For each active channel, a separate row for the channel settings is displayed.

Select the voltage range for the output channels: 0–5 V, 0–10 V, ±5 V, ±10 V or ±2.5 V.

Define the initial signal level present on the specific output after the application has been downloaded. The values can be set individually by entering the initial value for each channel according to the selected output range.

Define whether the initial value is also applied once the application has stopped. The behavior can be set individually for each channel using the checkbox.

Select the Input or Output direction for channels 1 to 8. For Output, the options Initial Value and Reset to Initial Value are displayed for each channel.

Individually select the Input or Output direction for channels 9 to 16. For Output, the options Initial Value and Reset to Initial Value are displayed for each channel.

Define the initial signal level present on the specific output after the application has been downloaded. The values can be set individually by choosing the initial value for each channel to be either Low (0) or High (1).

Define whether the initial value is also applied once the application has stopped. The behavior can be set individually for each channel using the checkbox.
