  2. The TPC and HMPID have already approached and (partially) implemented a FSM CS. As given examples, let’s see the HMPID prototype PVSS JCOP FW, SMI++, CAEN OPC, Simens OPC WN200 Workstation CAEN SY1527 PLC S7 PLC S7 C6F14 Circulation Low Voltage High Voltage Physical parameters Cooling Gas G. De Cataldo, CERN CH-INFN Ba, A. FrancoINFN Bari Kracow - LEB 2000 - 11-15/9/2000 G. De Cataldo, A.Franco; INFN-Bari - 14

  3. A possible HV State Diagram OFF The yellow states are automatically left when all the related actions are accomplished. GO_STANDBY (Config Name) RESET The GO_STANDBYcommand provides to the HV control program the “Name” of the configuration to be downloaded. CONFIG ERROR GO_OFF STATES OFF: The HV power supply is switched ON but no VH is on the channel output; STANDBY: all the board and channel parameters have been configured but no VH are on the channel output ON: after the HV Ramp Up, all the enabled channels have the set Voltage on the output. ERROR: alarm conditions, e.g.:over-current, over-voltage,over-temperature,……, push the control system in the ERROR state. Once the alarm condition is removed and the operator acknowledgement is given, then it will be possible to issue the RESET command and restart the system Alarm Conditions HVSS Configured ! STAND BY All Modules are in STANDBY ! GO_ON RMdw RMup RESET ON All Modules are in READY ! GO_RDWn G. De Cataldo, CERN CH-INFN Ba, A. FrancoINFN Bari

  4. HMPID DCS State Diagram OFF GO_STANDBY (Config Name) RESET The GO_STANDBY command provides to the control system the “Name” of the configuration to be downloaded. ERROR CONFIG GO_OFF Alarm Conditions All Sub System are Configured ! STAND BY All Sub System are in STANDBY ! During the Count Down to READY State, to operate safely the detector, the READY commands to all the sub systems are dispatched according to a defined sequence. This synchronization is ensured by the DCS control program. GO_READY Count Down to READY Count Down to STANDBY All DCS Sub Systems are READY ! READY GO_RDWn G. De Cataldo, CERN CH-INFN Ba, A. FrancoINFN Bari
