Status Assembly
The status assembly is a collection of status and diagnostic information for the
BridgeWay DeviceNet interface. The information in the assembly is updated once
a second.
Note: All information in the status assembly is stored in little endian format. The
least significant byte of multi-byte values is stored first.
