to the new value.
2. Send a Module Reconfigure message to the module.

EXAMPLE
Reconfigure an I/O module
When reconfigure[5] is on, the MOV instruction sets the high alarm to 60 for the local module in slot 4. The Module
Reconfigure message then sends the new alarm value to the module. The ONS instruction prevents the rung from
sending multiple messages to the module while the reconfigure[5] is on.
