Chapter 3 Send a message to multiple controllers
When the index equals the local_array_length, the controller sends the message to
all other controllers.
1. The first CLR instruction sets the index equal to 0. This lets the logic load
the configuration properties for the first controller into the MSG
instruction and start the sequence of messages again.
2. The second CLR instruction sets the LocalIndex member of the MSG
instruction equal to 0. This lets the logic load the value from the first
controller into the first element of local_array.
Restart the sequence
