OBS 6.3 - summary of implemented modifications



1) SPR 3045: LCU clear Command lock
The command HIFI_clear_LCU_comm_lock described by Luc in his TC ICD 1.10 has been implemented
Type,subtype  = 8,4
FID,AID = 25,0
SID= 0

IMPORTANT NOTE: the AID in the Luc Document is 19(dec), but the one provided by MIB 149 is 19 hex = 25 dec.
I've modified OBS to couple with MIB, instead of with TC ICD. This allows to do the tests with SCOS.



2) SPR 3048:
Upond discovering an LCU memory checksum error, the OBS issues the HL_STANDBY Command (0xF0020202).
Immediately after the command ingestion by LCU, OBS locks the communication with LCU by setting the
LCU_non_interaction flag.




3) SPR 3064: LCU mode Check
New TC specified in Luc TC_ICD 1.10.
The check is carried out on the HK packet at each HK run, in the HK_ask task
The check is carried out only if: HK lcu is ON + chk_mode_lcu is on + HK is valid
The check is active at Boot, with default Nbreach=1.
Only one action is taken onboard: Set LCU_non_interaction  flag (i.e. lock LCU commanding)
Then, the (5,1) event with code ERR_HK_ASK_LCU_MODE (0xB00A)

The HI_autonomous_S parameter in the ICU HK is updated following the scheme proposed by Luc and reported hereafter:

byte  bit
136	0	HI_autonomous_S
136	5	HI_au_LCU_mem_S
136	6	HI_au_LCUmode_S
136	7	HI_au_LCUresp_S
137	0	HI_auto_LOU_S
137	1	HI_auto_WBSH_S
137	2	HI_auto_WBSV_S
137	3	HI_auto_HTRH_S
137	4	HI_auto_HTRV_S
137	5	HI_auto_FCU8c_S
137	6	HI_auto_FCU8d_S
137	7	HI_auto_FCU8f_S




4) SPR 3065:
An error check procedure for the LCU similar to the procedure already in place for the FCU has been implemented.
The error check procedure monitors the periodic LCU HK and set LCU to standby when too many HK are missing (due to LCU not responding).
New TC specified in Luc TC_ICD 1.10.
New OOL report specified in Luc TM_ICD 1.11.
This function is NOT active at boot.
The function status is reported in the HI_autonomous_S parameter in the ICU HK. See point 3 above.
