Msg

ARINC 429 messages to send.

Tx Ctrl

This input port is available whenever the Show Transmission Control Input checkbox in the block mask is activated. Use this port to control which messages are to be transmitted during execution. Each ARINC 429 message may be controlled individually using an n-element uint32 vector, where n represents the Number of Messages. The indexing of the messages aligns with the order in which the messages are supplied to the Msg port.

Using the values within the uint32 vector, various options to manage the transmission of each individual message can be controlled:

• '0' to temporarily disable the message

• '1' to enable the message and transmit it at every sample step of the block

• Value d (>'1') to enable the message, but only send it at every d sample step of the block (e.g., d = '4' sends this message at every 4th sample step of the block)

The configuration details are all defined in the setup block.
