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:

Table 4-10.Upload Status Bytes

First Status Bit	8 = Control mode (with bit 9)
	9	= Control mode (00 = User, 10 = Profibus)
	10		= Setpoint status OK
	11		= Reserved
	12		= End of Target Life (EOTL)
	13		= Active toggle bit
	14		= Bus fault (high or low)
	15		= Reserved
Second Status Bit	0 = Reserved
	1	= Overtemperature condition
	2	= Interlock mechanism open
	3	= Momentary power failure
	4	= Reserved
	5	= Contactor not closed
	6	= Reserved
	7	= Output is on

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.
