COMMON STATUS
This is status information found by the DeviceNet master. The
common status includes four types of status information: DeviceNet
MPU status 1, DeviceNet MPU status 2, master function status 1, and
slave communication states 1 to 8.
The common status occupies up to 14 bytes (size of the common
status), beginning with the common status address.
