Unscheduled Messaging

The MBCN supports unscheduled messaging to other nodes on the

ControlNet network. It emulates the interface of the M/N 57C442 Data

Highway Plus module. It uses PCCC commands to communicate with

other nodes on the network.

This section describes how the messaging interface is organized in the

MBCN and provides examples of how the MBCN is accessed by the

application software. For more detailed information on programming,

refer to the AutoMax Programming Language manuals.

The MBCN supports sending messages on the local network only, not

through bridge modules.

The following table shows the memory organization. The following

sections describe the different register areas in more detail.
