2 SCX1 USA15 Common Infrastructure PC Local Area Network Server Operation Local Control Stations (LCS) Expert Subdetector 1 Subdetector 2a Workstations Subdetector n SCADA System CFS CFS UX15 Electronic Rack Sensors Partition 1 Actuators Partition 2 Power Supply Barrel Partition 3 Supervisory only Detector Element Partition m Front-End System Fieldbus 100m 500 kbits/s ATLAS TDAQ week, July 6th 2001, H.J.Burckhart 2

3 Supervisory Control And Data Acquisition Usage of a commercial system Software product PVSS of company ETM purchased Licenses free of charge for ATLAS work Functionality Acquisition, analysis and archiving of data operator interface (status display, actions) take automatically corrective actions execution of complex or repetitive procedures Work done within JCOP Common Framework for LHC experiments standard applications (e.g. gas, alarm handling) ATLAS TDAQ week, July 6th 2001, H.J.Burckhart 3

4 UIM UIM UIM User Interface Layer Ctrl API Processing Layer DM EV Communication and Memory Layer D D D Driver Layer ATLAS TDAQ week, July 6th 2001, H.J.Burckhart 4

5 Operator Application DAQ Connection Internet Web Browser User Appl. PVSS Internal Communication PVSS 01 e.g. sub-detector 1 PVSS 02 - n OPC Industrial Equipment E.g. PLCs Fieldbuses Other Front-ends E.g. VME, FEC PLC, ATLAS TDAQ week, July 6th 2001, H.J.Burckhart 5

6 Responsibility of sub-detectors Connection to SCADA standardized CERN recommended Fieldbus CAN JCOP recommended SW protocol OPC VME Programmable Logic Controller PLC (e.g. gas, cooling) other connections have to be individually agreed upon General-purpose I/O system Embedded Local Monitor Board ELMB ATLAS TDAQ week, July 6th 2001, H.J.Burckhart 6

7 SCADA CAN 500 m u-processor eg. CAN protocol CAN open I/O processing SPI 2 m I/O function eg. ADC DAC digital I/O JTAG I2C? Signal adaptation eg. multiplexers sensor current R-network 30 m Signals and Sensors eg. Voltage Current Temperature Pressure B-Field Hardware Interlocks Equipment overall1.cdr ATLAS TDAQ week, July 6th 2001, H.J.Burckhart 7

8 Flexible I/O functions multiplexed ADC, 16 bit, 64 channels 8 input and 16 output lines SPI bus new: DAC, 12 bit, channels Signal adaptation on motherboard HW interlock system Remote diagnostics and reset Loading of SW in situ Low cost (order of 100$ US) ATLAS TDAQ week, July 6th 2001, H.J.Burckhart 8
