Message Merge

Combine message paths

Since R2021a

Libraries:
Simulink / Messages & Events

Description

The Message Merge block graphically combines multiple message lines into a single message line. Merging message lines does not change the messages themselves. You can specify the number of message lines to merge.

Use this block when you want to merge multiple incoming messages and output to a single destination such as a queue or a message storage block.

Note

Message Merge block is not supported for code generation in AUTOSAR mode.
