IO752 - Receive v3
IO752 - Receive v3 — Outputs the cyclic data
received from the remote PROFINET controller.
Library
Simulink Real-Time - Speedgoat
Description
This block outputs the cyclic data the I/O module receives from the remote
PROFINET controller. For acyclic communication, use Record blocks.
Your model can contain only one Receive block for each
I/O module in your target machine.
Ports
Outputs
The block outputs the output data items of the sub-modules defined in
the Data Module Configuration parameter
of the corresponding Setup block. The number, types and dimensions of
the output ports depend on the mask parameters. The block has either:
one port for each data item
one port for each sub-module
one port for each module, or
one port in total that outputs the entire output data of
the device
Inputs
This block does not have any input ports.
Parameters
-
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.
![[Caution]](images/caution.png) | Caution |
|---|
All blocks that interface with the same I/O module must have identical
sample times. |
-
Output Level
Defines the granularity of the data output. There are 4 options:
Data Item: Each port represents one data item and inherits its
type and length from the Data Module
Configuration parameter of the corresponding
Setup block
Sub-Module: Each port represents one sub-module. The data
items of the sub-module are packed in a vector of data type
uint8
Module: Each port represents one module. The data items of the
module's sub-modules are packed in a vector of data type
uint8
Device: One port outputs the entire output data of the device
as a vector of data type uint8
Use Byte Unpacking blocks to extract data items from byte
vectors.
-
Group Data Items as Vector
Places the data items of a sub-module into a vector. This reduces the
number of ports and therefore improves usability. All data items must be
scalar and must have the same type. If the sub-module has at least one
data item of another data type, the parameter has no impact and the
block creates a port for every single data item.
-
Port Label Elements
Shows or hides specific elements of the output port label. The
elements available include the module name, the sub-module name and the
name of the data item. The resulting port label also depends on the
Output Level parameter as you
cannot show the sub-module name if the output level is module, for
example.
