IO758 - Receive
IO758 - Receive — Receives cyclic data from the
POWERLINK managing node
Library
Simulink Real-Time - Speedgoat
Description
This block is used to receive data from the POWERLINK managing node connected with
the IO758 module.
Your model can contain only one Receive block for each
I/O module in your target machine.
Ports
Outputs
One vector of data type UINT8 which the block reads from the input
data area of the dual-port memory. This area contains data which has
been received from the POWERLINK managing node. Use Byte Unpacking blocks to extract specific
data. The Number of Bytes parameter
sets the length of this vector.
Type:
scalar | vector
Data Type:
uint8
Inputs
This block does not have any input ports.
Parameters
-
Module ID
This ID defines the link to the corresponding Setup block
-
Port Type
Always select 1 port with n element vector of type
uint8
-
Number of Bytes
This parameter defines the length of the output port and thus the number of
bytes to be read from the module's input data area (RX). Refer to the usage
notes to learn how to use this parameter.
-
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.

All blocks that interface with the same I/O module must have identical
sample times. |
