Controller Mask

The controller condition corresponds to a standard message called the mask.
When a message is received, it is compared to the set of declared masks.
The system retains the controller which has the closest mask to the receive message.

For instance, the following controller have been declared :

• Mask 1 : 0
• Mask 2 : 0 100
• Mask 3 : 0 100 10

The controller selection is done like this :

• 0 100 -> Mask 2
• 0 100 10 -> Mask 3
• 0 100 11 -> Mask 2
• 0 102 -> Mask 1
• 0 102 10 -> Mask 1
