I need to transmit CAN messages neither periodicly nor on data change, which are the only two options in the CAN Transmit block. Putting the CAN Transmit block within a triggered subsystem doesn't seem to prevent the transmit if periodic is selected once it triggers the first time. Is there a way to indicate to trigger a CAN Message transmit asynchronously based on some logic within my model?
As a quick example of a use case, the heartbeat protocol from CANOpen would have a single message on a device's logical 'boot' with data 0x00. After that, the device moves to pre-op and a periodic message is sent with data 0x7F at some defined rate. If a NMT start is received, the data changes to 0x05 for operational. If a NMT stop is received, the message stops transmitting completely.
