LBT Q 2 2008 Eng/SW Review MCSC – Mount Control System

Progress HBS and Rotator support Add variables to Data Dictionary to make available to TCS (done for ROT) Add MCSPU commands to MCS to make available to TCS (done for ROT) Numerous Events need to be defined for the Event Logging System (some progress) Alter AZ/EL/ROT Hold commands to stop telescope more gently √ Make existing AZ/EL software use/monitor newly available information from the HPLC (not done) Repair ELRL read head √ Install ELFR read head preload spring (postponed due to telescope schedule) Work on punch list for commissioning √ July 21, 2008 LBT Q 2 2008 Eng/SW Review 2

Additional Progress HBS and Rotator support We now have a good solution to Siemens Communication problem in hand √ Test MCSPU Rotator Cable Chain software. (mostly done) Improved MCS el. Hold and az. Hold commands √ July 21, 2008 LBT Q 2 2008 Eng/SW Review 3

Open Issues Technical Encoder reset is not as reliable as it should be (probably a hardware issue). AZ/EL start-up procedure not as reliable as it should be (probably a TPLC issue). ELFR main encoder read head preload spring is missing Software stopped using the elevation strip encoder - issue 1326 (broke while implementing ROT) Cleanup necessary for commissioning None MCS competing for engineering resources Schedule Financial Resource July 21, 2008 LBT Q 2 2008 Eng/SW Review 4

Planning Make existing AZ/EL software use/monitor newly available information from the HPLC Fix bug that caused elevation to ignore the strip encoder Install preload spring on ELFL encoder July 21, 2008 LBT Q 2 2008 Eng/SW Review 5
