  11. CGSE control system need to get from the magnet the following parameters (Confirmed at the TIM@cern April 2006) • Temperatures of helium cooling flow across the magnet T21, T19 and their difference (T21-T19).(from CAB) • (This temperature difference should be not more 50 K during cooling of the magnet in the range 300-80 K ) 2. Helium temperature T07 . (from CAB) ( for control of pumping AMS magnet to super fluid state at 1.8 K ) following parameters for filling up procedure: 3. Signal from helium level meters L02, L03. (CGSE direct from the meters) 4. Pressure in AMS main helium tank P04, P05. (from CAB) 5. Temperatures of the AMS VCS T09-T12 . ( from CAB) 6. AMS temperatures in SFHe Cooling Loop (T01-T06). (from CAB ) 7. Position of AMS valves: open or close. (Some from CAB, some from CGSE and new table from SCL/McMahon 5 May,2006)

  12. 1 Communicating Module based on CANbus CAN Master CAN Slave TCP_Client Display Interface Display Interface Display Interface Response and Data Control Command and Receive Data Command and Data Transmitting CAN Slave Port Socket Client port CAN Master Port Socket Server Port CAN Net Ether Net Function ofCAN Master, TCP_Client and CAN Slave 1 CAN Master is mainly used at the connection and communication between CAN networks and TCP/IP networks. It functionally works as angateway. 2 Function of TCP Client is to Simulate CGSE sending commands to TCP Server (CAN Master) through the TCP/IP networks and receiving its response. 3CAN Slave is mainly used to simulatethe slave node (CAB) of CGSE, and implement the functions such as data-feedback, reading the values of locale data-collection equipment, etc.
