Now fixed and temperature around 40 °C DCS is always running (see Giovanni Talk) LabVIEW (D. Lomidze) test program is under installation for more than 900 hours

P. Paolucci - I.N.F.N. di Napoli 9 MTCC meeting May 06 RPC DCS for MTCC

P. Paolucci - I.N.F.N. di Napoli 10 MTCC meeting May 06 To be done for MTCC Move to RPC condition db on SX5 and test the performance. Release the CMS_RPCfwHardware Component Help our Warsaw friends, creating a control and monitoring system of the LB low voltage, and integrate it into the RPC DCS. Do we want to integrate it in the FSM ?? It will be also discussed tomorrow in the DCS working group. Test all the system when the hardware will be ready at SX5 (June 06). Write documentation and organize training in order to have more people ready to take data.
