Rhythmic oscillations, inductive spikes or random interference can disrupt the network communications. The corruption signal source may be outside
electrical interference such as motors or solenoids or internal interference generated from a module on the network. In some cases, an open in either the
data (+) or data (-) circuit to a network module may cause the module to emit interference on the one circuit which is still connected. The trace shown is
an example of a "sawtooth" pattern transmitted from a module with one open network circuit.
Other corruptions may be present when a module is intermittently powered up and down. The module on power up may initiate communication out of
sync with other modules on the network causing momentary communication outages.
Controller Area Network (CAN) Multiplex Messages
Modules on the CAN utilize simultaneous communication of 2 or more messages on the same network circuits. The following chart summarizes the
messages sent and received on the network.

NOTE: This chart describes the specific HS-CAN and MS-CAN messages broadcast by each module, and the module(s) that receive the message.
