Message triggers

The Message Triggers is responsible for managing and automating the transmission of data packets to external interfaces. These blocks act as "logical switches" that determine when specific information should be transmitted through the system's communication channels.

CAN message trigger

CAN message trigger block acts as an activator for CAN producers. Its primary function is to trigger the transmission of a specific, previously configured CAN custom message based on a logical event within the control program.

CAN message trigger block

When the input signal receives a boolean TRUE value, the block commands the corresponding CAN producer to transmit the assigned message over the network.

  • Input

Pin 0: Enable bit.

  • Configuration menu :
CAN Producer Trigger block configuration

  • CAN Producer: Allows the selection of which CAN Producer instance is to be triggered.

  • Message ID: Specifies the exact message that must be sent.

  • Initial Delay: Waiting time before the first message is sent after the trigger is activated.

  • Periodic:

    • If disabled, the message is sent once as soon as the input transitions from False to True.

    • If enabled, the message is sent repeatedly as long as the input remains True.

  • Period: If the Periodic mode is active, it defines the time interval (in seconds) between consecutive transmissions of the message.

Serial producer trigger

Serial message trigger block serves as an activator for serial communication. It is designed to trigger the sending of serial custom messages through the autopilot's serial ports.

Serial message trigger block
  • Input

Pin 0: Enable bit.

  • Configuration menu:
Serial Producer Trigger block configuration

  • Producer: Selection of the Serial Producer instance that contains the message definition.

  • Message ID: Selection of the specific message within the chosen Producer to be sent to the serial bus.

  • Initial Delay: Initial delay before the message is actually transmitted after the input becomes True.

  • Periodic:

    • If disabled, the message is sent as a single event when the input transitions from False to True.

    • If enabled, the message is transmitted cyclically as long as the input condition remains True.

  • Period: The time interval between consecutive message transmissions when the Periodic mode is active.
