IO203 - Read v2
IO203 - Read v2 — Reads the IO203 digital
inputs
Library
Simulink Real-Time - Speedgoat
Description
The IO203 Read block is used to read the channels defined as digital inputs in the
Setup block.
For each IO203 module, only one Read block is permitted.
Ports
This driver block has no input ports. The number of output ports is determined by
the IO203 Setup block configuration, and the Port
Configuration setting of the IO203 Read block. The channel
configurations are transmitted by the Setup block; the Read block does not
automatically request these configurations. If the Setup block is configured before
the Read block is added to the model, then the Setup block must be reinitialized (by
changing a setting and clicking Apply, or by
updating the model) in order to update the new Read block.
The output ports can be configured in the following two ways:
1 port with a 64-element vector
One output port with a fixed width of 64 is used. The index of each array element
is equivalent to the channel number. Each element has a value of either 0 (Low) or 1
(High). Array elements for channels that have not been configured as digital inputs
remain 0.
1 port for each active input channel
For each channel configured as digital input, one port is added to the IO203 Read
block. Each port outputs a scalar with a value of either 0 (Low) or 1 (High).
Data Type
Select either Boolean or Double as the output data type.
Parameters
-
Module ID
This ID defines the link to the corresponding Setup block
-
Port Configuration
Select one of the two available port types.
-
Data Type
Select the data type of the block output signals.
-
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.
