Typedefs

typedef enum _LTC_DB_FileIdTypes LTC_DB_FileIdTypes

Typedef for enum _LTC_DB_FileIdTypes.

typedef struct _LTC_DB_CommonParams LTC_DB_CommonParams

Typedef for structure _LTC_DB_CommonParams.

typedef struct _LTC_DB_PduMeasRec LTC_DB_PduMeasRec

Typedef for struct _LTC_DB_PduMeasRec Each LTC_DB_PduMeasRec structure entry in the LTC_DB_PduTbl table maps one LAT PDU environmental ADC to an LTC sensor slot. The LTC_DB_PduMeasRec.hp member assigns the sensor to a particular heat pipe (0 - 11). This is primarily dictated by hardware, but the values could be changed in extreme circumstances such as the failure of a close-by sensor. The LTC_DB_PduMeasRec.sTyp should be one of the LTC_DB_SnsrType values. There should be one of each LTC_DB_SnsrType entry in the LTC_DB_PduTbl for each heat pipe (6 types x 12 heat pipes = 72 entries). The LTC_DB_PduMeasRec.adc value is the PDU hardware ADC address within an environmental group. See the "PDU Programming ICD Specification" manual for a list of the thermal control ADC addresses.

typedef struct _LTC_DB_PduTbl LTC_DB_PduTbl

Typedef for struct _LTC_PduTbl The LTC_DB_PduTbl structure contains the mapping from ADC hardware address in the PDU to LTC sensor selection. The array of LTC_DB_PduMeasRec is arraged per group, with the LTC_DB_PduTbl.nm array providing the number of members in each group. The ADC groups in the PDU are indexed from 0 to 6, with each group containing up to 20 ADC's. See the "PDU Programming ICD Specification" manual for a list of the thermal control ADC group assignments.

typedef struct _LTC_DB_Schema LTC_DB_Schema

Typedef for struct _LTC_DB_Schema.

Enumerations

enum _LTC_DB_FileIdTypes {
  LTC_DB_FILE_BUILT_IN = 0,
  LTC_DB_FILE_BY_NAME = 1,
  LTC_DB_FILE_BY_ID = 2
}

Values for LTC configuration types. This value controls how LTC will configure itself at startup. The value LTC_DB_FILE_BY_NAME is obsolete and should not be used. Assigning a value of LTC_DB_FILE_BUILT_IN means that LTC will use a built-in default configuration at startup. This default configuration applies to all heat pipes and includes control limits, ADC/temperature conversion tables, and filter coefficients. Assigning a value of LTC_DB_FILE_BY_ID means that the LTC_DB_Schema.cfgF member should contain a valid LAT on-board file ID value. When LTC starts in this mode, it will attempt to open and parse the master configuration file referred to by this ID value. The configuration contained in the file will be used at startup by LTC.

  LTC_DB_RSVR_HTR = 4,

Values for LAT sensor types used as array index by LTC. Each heat pipe has two active sensors associated with it. One is the RIT sensor and the other the RES sensor. LTC allows assignment of different sensors to each of these slots reserved for each heat pipe. The RIT sensor may be one of the set (LTC_DB_DSHP_RIT, LTC_DB_DSHP_RIT_R, LTC_DB_XLHP_RIT, LTC_DB_XLHP_RIT_R). The RES sensor may be one of the set (LTC_DB_RSVR_HTR, LTC_DB_RSVR_HTR_R). More...

Enumeration Type Documentation

enum _LTC_DB_FileIdTypes

Values for LTC configuration types. This value controls how LTC will configure itself at startup. The value LTC_DB_FILE_BY_NAME is obsolete and should not be used. Assigning a value of LTC_DB_FILE_BUILT_IN means that LTC will use a built-in default configuration at startup. This default configuration applies to all heat pipes and includes control limits, ADC/temperature conversion tables, and filter coefficients. Assigning a value of LTC_DB_FILE_BY_ID means that the LTC_DB_Schema.cfgF member should contain a valid LAT on-board file ID value. When LTC starts in this mode, it will attempt to open and parse the master configuration file referred to by this ID value. The configuration contained in the file will be used at startup by LTC.

Enumerator:

LTC_DB_FILE_BUILT_IN	No config file, use built-in defaults
LTC_DB_FILE_BY_NAME	File identified by string (obsolete)
LTC_DB_FILE_BY_ID	File identified by ID number

enum _LTC_DB_SnsrType

Values for LAT sensor types used as array index by LTC. Each heat pipe has two active sensors associated with it. One is the RIT sensor and the other the RES sensor. LTC allows assignment of different sensors to each of these slots reserved for each heat pipe. The RIT sensor may be one of the set (LTC_DB_DSHP_RIT, LTC_DB_DSHP_RIT_R, LTC_DB_XLHP_RIT, LTC_DB_XLHP_RIT_R). The RES sensor may be one of the set (LTC_DB_RSVR_HTR, LTC_DB_RSVR_HTR_R).

Enumerator:

LTC_DB_DSHP_RIT	Downspout RIT
LTC_DB_DSHP_RIT_R	Downspout RIT redundant
LTC_DB_XLHP_RIT	X-LAT RIT
LTC_DB_XLHP_RIT_R	X-LAT RIT redundant
LTC_DB_RSVR_HTR	Reservoir heater
LTC_DB_RSVR_HTR_R	Reservoir heater redundant
LTC_DB_LTC_SNSR_TYPS	Number sensor types
