Network Message Chart - Displays 

The data in each display is shown when the IPC receives messaged inputs from other modules on the CAN, unless the display data is controlled exclusively by the IPC. The IPC communcates on the HS-CAN3. If the originating module communicates on a network other than the HS-CAN3, the messaged signals are sent to the GWM first, then to the IPC.

Network Message Chart - Information-On-Demand Displays 

The information-on-demand displays are selected using the menu screens in the message center. The data in each display is shown when the IPC receives messaged inputs from other modules on the CAN, unless the display data is controlled exclusively by the IPC. The IPC communcates on the HS-CAN3. If the originating module communicates on a network other than the HS-CAN3, the messaged signals are sent to the GWM first, then to the IPC.

Network Message Chart - Warning Messages 

A warning message is displayed in the message center when the IPC receives messaged inputs from other modules on the CAN, unless the message is for a function exclusive to the IPC. The IPC communcates on the HS-CAN3. If the originating module communicates on a network other than the HS-CAN3, the messaged signals are sent to the GWM first, then to the IPC.
