IO143 - Digital Output

IO143 - Digital Output — Writes the IO143 digital outputs


Simulink Real-Time - Speedgoat


To write to the digital outputs, one of these blocks must be added to your model for each IO143 I/O module in your target machine.


This driver block has n double-type scalar input ports, where n is the number of selected digital output channels.

X (X is the digital output channel number)

Use the following values to set digital output channel X:

  • 0 - TTL low

  • 1 - TTL high

Data Type: double


The configuration details are all defined in the setup block.

Module ID

This ID defines the link to the corresponding Setup block.

Sample Time

Defines the base sample time at which this driver block gets its sample hit. This parameter can also be set to -1 for inherited sample time. The units are in seconds.
