3.9 Application Software Requirements
AVI-1465/CREATED/T
The Avionics SCOE Application Software shall provide the following functions:
Initialization of the SCOE
Control & Monitoring Sessions
Data Logging
Command & Control Link to the CCS
Avionics SCOE MMI
3.9.1
Initialization of the SCOE
AVI-1466/CREATED/T
The Avionics SCOE initialization process shall be scheduled automatically at start up, and shall
include:
Configuring the instrument interfaces to the Spacecraft
Map data I/O symbols to hardware channels
Setting up default values to the Spacecraft hardware
Defining the initial data logging scheme
Setting up the interface to the RTS
Establishing a link to the CCS (if connected)
AVI-1505/CREATED/T
The initialization process shall configure all instrumentation hardware for nominal operation.
AVI-1509/CREATED/T
All data I/O with the Spacecraft interfaces are identified by software Symbolic Name (see Appendix
A). Mapping of the SCOE hardware channels to Symbolic Name shall be defined in an initialization
file.
AVI-1511/CREATED/T
The initialization process shall map the SCOE hardware channels by Symbolic Name defined in the
initialization file.
AVI-1512/CREATED/T
All instrumentation providing stimulus to the Spacecraft interfaces shall be configured for default
output values.
AVI-1513/CREATED/T
Default stimulus values shall be defined in an initialization file.
AVI-1896/CREATED/T
Default 1553 and SpaceWire BUS configuration shall be defined in an initialization file (i.e., which RT
or SpaceWire terminals need to be simulated to replace missing Spacecraft units).
AVI-1514/CREATED/T
For closed loop operation (the RTS defining the data I/O), the RTS shall define the initialization
parameters.
AVI-1904/CREATED/T
The default Data Log Schedule shall be defined initially by initialisation file.
AVI-1905/CREATED/T
The Datalog initialisation file shall determine which parameters are to be routinely logged (locally, to
the CCS or both) and/or displayed, and the nominal data logging rates.
