  1. LBT TCS Overview Tim Axelrod LBT Observatory 22 March 2005

  2. Features of LBT Software Architecture • System is partitioned into autonomous subsystems • Common software architecture manages diverse hardware architectures • Separate 1 GB networks for • Command delivery • Reflective memory • Telemetry • Central command sequencer • Single subsystem archives all telemetry streams and event logs • All subsystems built on common infrastructure: LBT Common SW

  3. LBT Common Software • Common SW provides facilities for • Command delivery and decoding • Event generation and delivery to subscribers • Data dictionary to store attributes of all subsystem variables • Low-latency access to global system status using reflective memory • Implementation • C++ class libraries • Documented with Doxygen • V0 has been released and is in active use

  4. LBT System Logical Organization

  5. Instrument – TCS Communication Instrument Hardware Inst Hdw Net Displays Local/Remote Instrument Controller IIF TCS Cmd Net

  6. Instrument Interface (IIF) • IIF V0 has been released to instrument teams • Offers basic commands, supports first light • Suitable for all but highest bandwidth Instrument <-> TCS communication • Subsequent versions will support multiple focal stations, AO, interferometry • Tim Schmelmer (MPIA) is principal contact
