IO907/IO908 - Broadcast
IO907/IO908 - Broadcast — Generates a network
interrupt
Library
Simulink Real-Time - Speedgoat
Description
The Broadcast driver block generates a network interrupt that other boards in the
shared memory network can detect.
Ports
Inputs
-
En
This input port is a Boolean input that can enable or disable the
transmission of a network interrupt. For continuous interrupts. connect
this input port to a Constant block with a Boolean value of true (1). If
you want to enable interrupts only part of the time, you can use another
kind of input, such as a pulse generator.
-
Data
This input port allows you to transmit a data value (uint32) with the
interrupt.
Parameters
-
Module Type
Select the type of your I/O Module installed in your target
machine.
-
Module ID
This ID defines the link to the corresponding Setup block
-
TargetNode (-1: Global)
Enter the node ID of the node to which to broadcast the interrupt.
Enter -1 to broadcast the interrupt to the nodes in the shared memory
network. You cannot broadcast the interrupt to another subset of nodes.
-
Interrupt Number
Enter the shared IRQ number. This value is the special interrupt
number that two boards use between each other for synchronization (refer
to the Usage Notes). This
value must match the value of X in a line like the following, which you
can specify for the receiving end of the shared memory network:
node.Interface.Interrupts.PendingIntX
-
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.
