- The COMMAND BOX drives the 2 stepper motors for X/Y movements- The remote LAPTOP, via the 232/422 INTERFACE, is connected to the COMMAND BOX with the RS422 LINK- It sends « LEVEL-1 commands » (ASCII) to the COMMAND BOX (left/right moves, reading position, etc…)

- The LOCAL CONSOLE has been connected to the COMMAND BOX- There is a LOCAL MODE switch (inhibits the LAPTOP commands) + a BRAKE OFF Switch (isolates the BRAKE)- For each motor, there are 3 basic commands (PUSH Buttons) : Forward, Backward, ZERO position, plus 1 SPARE

- 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 ? ) …

Laptop Windows

RS422R232

- 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

Laptop Windows

RS422R232

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

Laptop Windows

RS422R232

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
