J1939 Message Triggering (not recommended)
Simulink® Real-Time™ Library of Drivers No Longer Recommended for Use
The J1939 Message Triggering block manages the multiple trigger conditions possible for triggering the transmission of a J1939 message.
This block has the following input ports:
Receives the signal that indicates when the block is enabled.
Receives the signal that indicates a request to send has been received.
Indicates when a message is in the active state.
Receives the signal whose change triggers the sending of a message.
This block has the following output ports:
Signal of type double that is set to
the message should be packed. It is typically connected to the input
port of a J1939 Pack block.

Select this check box to repeat at the interval specified in the Repetition Interval parameter.
Specify the enabled repetition interval in milliseconds. The repetition interval should be an integer multiple of the model update rate.
Select this check box to enable the message to repeat at the interval specified in Interval when Active when the external signal is active.
Enter the active repetition interval in milliseconds. The interval should be an integer multiple of the model update rate.
Select this check box to send the message when the input signal that is wired to the change port changes by the value in the Change threshold parameter.
Enter the threshold for message transmission to any
or a change greater than 10% (
Enter a minimum change interval.
