Bus address
What is Bus address?
The identifier under which a node is addressed on the bus. It must be unique; two devices with the same address cause dropouts or jumping readings.
What matters about Bus address in practice?
On the P-Bus, nodes are registered and named on the monitor; there are no address switches on the device. Naming is the step people like to skip and regret a year later: six relay outputs without names are six outputs to try out.
On the chartplotter the same idea appears as instance assignment: if battery data comes from two directions, you must define which source feeds which display.
