12. CGSE control system need to get from the magnet the following parameters (Confirmed at the TIM@cern April 2006) 1.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).

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