Fields:

HeaterCommand (index)

Attribute(s):  

Brief:  "Current heater command and LTC control mode"

Instance(s):  htrCmd

For the heater bits, a value of '0' indicates that LTC is commanding the heater off. A value of '1' indicates that LTC is commanding the heater on. These heater commands are applied only when LTC is in active control mode.

HeaterMode (index)

Attribute(s):  

Brief:  "Control mode for VCHP heaters."

Instance(s):  actvHp

A bit value of '0' indicates that the heater is under manual, user control. A bit value of '1' indicates that the heater is under automatic, algorithm control.

HeaterState (index)

Attribute(s):  

Brief:  "Current heater state and LTC run mode"

Instance(s):  htrReg

For the heater bits, a value of '0' indicates that the heater is currently off. A value of '1' indicates that the heater is currently on.

Padus16 (index)

Attribute(s):  

Brief:  "Explicit 16 bit pad in unsigned short"

Instance(s):  spare, spares

Explicit 16 bit pad in unsigned short

ResRitSnsrSel (index)

Attribute(s):  

Brief:  "Selected RSVR and RIT sensors"

Instance(s):  snsrSel

ResRitStatus (index)

Attribute(s):  

Brief:  "Heat pipe RIT and reservoir sensors status"

Instance(s):  snsrStatus

TempCelsius (index)

Attribute(s):  

Brief:  "Temperature converted to celsius."

Instance(s):  temps

Fixed point scaled by 8 bits (256).
