Page 6 CALICE Collaboration Didier JEHANNO – v2 – 25.06.04 DAQ EQUIPMENT CONNECTION X Y Laptop Windows RS422 R232 - The purpose is to DEFINE, then SPECIFY the LINK between the LAL and the DAQ systems - QUESTIONS :  which datas are required by the DAQ ?  which period of refreshment ? Cyclic, event ? On DAQ request ?  which medium is the best choice ? Serial (baudrate ? RS232, RS422 ? Protocol ?) Ethernet (10/100M ? Protocol ? Client/Server architecture ? ) … AC LAL SCOPE OF SUPPLY DAQ SYSTEM To Be Defined ???

7. Page 7 CALICE Collaboration Didier JEHANNO – v2 – 25.06.04 LAL POLICY X Y Laptop Windows RS422 R232 - WHAT THE LAL SYSTEM PROVIDES WITH THE LAPTOP :  LEVEL-1 commands (password required) : the lowest existing level ( ie frame level)  LEVEL-2 set of instructions : for remote requests/commands dedicated for DAQ  Graphical HMI for X/Y positions, status of the Motors, etc… - WHAT THE DAQ WILL NOT HAVE :  no possibility to drive the motors via Level-1 commands : for safety reasons  the only entry point for the DAQ system will be LEVEL-2  no access to the RS422 medium : for layer abstraction, required if control box changes  no shared RS422 medium  no possibility to adjust move speed for any axis : for safety reasons - WHAT THE LAL SYSTEM PROVIDES TO THE DAQ SYSTEM :  LEVEL-2 set of instructions which are parsed and validated before sending them to the Control Box AC LAL SCOPE OF SUPPLY DAQ SYSTEM To Be Defined ???

8. Page 8 CALICE Collaboration Didier JEHANNO – v2 – 25.06.04 SUGGESTED DATAS X Y Laptop Windows RS422 R232 LAL PROPOSES THE FOLLOWING DATA FOR EACH AXIS, provided at LEVEL-2 : the DAQ system has access to them, but it is up to it to use them or not  PARAMETERS (constants) :  conversion (one Motor Step) / distance (mm)  maximum moves allowed in (mm) and (step) (X : 30cm and Y : 20cm)  preset speed for translation  VARIABLES :  current position  current gaps between current position and maximum move allowed  global status : motor health status / stepper driver status  end position sensors status  OTHER VARIABLES :  console presence status  console switches status : « Local Mode » / Y « brake off » switch / Y brake status  console push-buttons status : Forward / Backward / Zero / Spare AC LAL SCOPE OF SUPPLY DAQ SYSTEM To Be Defined ???

9. Page 9 CALICE Collaboration Didier JEHANNO – v2 – 25.06.04 SUGGESTED COMMANDS X Y Laptop Windows RS422 R232 LAL PROPOSES THE FOLLOWING COMMANDS, provided at LEVEL-2 : May change further !  READ PARAMETERS : rp [x/y] read all parameters for X or Y axis  READ VARIABLES : rv [x/y] read all variables for X or Y axis  MOVE AXIS : mv [x/y] [value] [unit] for X or Y axis, value is according the unit : step or µm / mm / cm  MOVE ZERO AXIS X : ze [x/y] returns to reference position 0 for X or Y axis  Y BRAKE COMMAND : bky [on/off] on validates the Y brake / off inhibits it, even if Y motor is stopped  POWER MOTOR X : pox [on/off] on validates hold torque / off validates detent torque when stopped  POWER MOTOR Y : poy [on/off] on validates hold torque / off validates detent torque when stopped AC LAL SCOPE OF SUPPLY DAQ SYSTEM To Be Defined ???
