2.2.3 Interface between ISAC-PLN and the Software
for instrument operations

• Examples are shown for
• SOE
• PRADA
• After introduction of ISACS-PLN system

ISACS-PLN overview

• Generation daily command sequence for S/C (and
  instruments)
• Full automatic generation as well as manual
  specification
• Sequence of Event (SOE)
• Ground station, Day/Night, .
• Rule for events to expand sequence of commands
  written in PRADA language

PRADA POINT definition
File Sample1.prd (1/6)

• POINT_BLOCK
• POINT OP_REGIST AT OP_START -1800s / OP
  start 30 min before /
• POINT OP_EXEC_START AT OP_START -1s / OP
  start 1 sec before /

PRADA Sequence (OG)
File Sample1.prd (2/6)

• SEQUENCE NOP_OG (OG)
• NUMBER 1
• CMD NOP_NOP
• SEQUENCE OP-STOP-OG (OG)
• NUMBER 511
• CMD NOP_NOP

• SEQUENCE Day_OG (OG)
• NUMBER 41
• CMD CTRL_AUTO
• SEQUENCE Night_OG (OG)
• NUMBER 42
• CMD CTRL_MANU

Note OG is a kind of sequence realized by
DHU. Only OG can executed from OP(time line).

PRADA Sequence (OP)
File Sample1.prd (3/6)

• SEQUENCE Day_Seq (OP)

Note OP is a time line commands stored in
DHU. ISCAS-PLN embeds command in Seq. into OP

Development Status

• Initial version of ISACS-PLN system with PRADA
  compiler is available for EIC/MIC of Astro-F
• Mode is not supported yet
• Some other limitations
• Fully implemented version will be available
  before launch of Astro-F (Summer of 2003)
