Login Response

A Login Response message is sent in response to a Login Request message. On a successful login, the LoginResponseStatus will be set to A. On a failed login, LoginResponseStatus will be set to a value other than A, and LoginResponseText will be set to an appropriate failure description.

Note that the repeating group starting with field UnitNumber provides the highest available CFE to TPH sequence number for the specified unit. Only the unit of the port will populate this group (i.e. NumberOfUnits will be 1).

Field Name	Offset	Length	Data Type	Description
StartOfMessage	0	2	Binary	B0 E3 (58288)
MessageLength	2	2	Binary	(76 + NumberOfUnits*5)
MessageType	4	2	Binary	F5 01 (501)
MatchingUnit	6	1	Binary	Will be zero
Reserved	7	1	Binary	Unspecified
SequenceNumber	8	4	Binary	Will be zero
LoginResponseStatus	12	1	Text	Accepted, or the reason for the rejection. A = Accepted B = Session In Use D = Disabled I = Invalid Unit M = Invalid Message N = Not Authorized Q = Sequence Ahead S = Invalid Session
LoginResponseText	13	60	Text	Human-readable text with additional information about the reason for rejection. ASCII NUL (0x00) filled on the right, if necessary.
ClientSequence	73	4	Binary	Last inbound (TPH to CFE) message sequence number processed by CFE on this port.
NumberOfUnits	77	1	Binary	A number, n, of unit/sequence pairs to follow, one per unit. A pair for every unit will be sent, even if no messages have been sent to this port today. For unsuccessful logins, this will be 0. This value will be 1 since all BOEv3 ports are associated with a single unit.
→UnitNumber	78	1	Binary	A unit number
→UnitSequence	79	4	Binary	Highest available CFE to TPH sequence number for the unit.
