Bytes 0 and 1 of the upload packet contain information about the Apex generator; this 
information appears as status bits (or status “flags”). The following table defines these 
status bits:

In the first status byte, bit 13 (the active toggle bit) indicates, the status of the Profibus 
interface. After the Apex generator has powered up, this bit’s continuous change 
indicates that the Profibus interface is ready. During operation, a cessation of this 
change indicates that a communication problem exists.
