Class Description


this device is used to control a specific sample environnement called Cell Couette.

This equipement is consisted of 3 parts: - the motor controller - the torque controller - temperature controller

the multiplexage is ensured by a multipoint link RS-485. but sometime theses controllers can be in concurrency. To improve the communication, THE STATE COMMAND MUST BE POLLED BY THE USER (under JIVE application). The other attributes which read on the hardware are polled by default.

Moreover, to ensure the communication , the elapsed time between 2 RS232 requests is at least 500 ms

The device communicates with controllers by using the Serial Device (RS232 communication) the communication parameters of the associated proxy device server called Serial are: Baudrate = 19200; Charlength = 8; Newline = none; Serialline = COMx; stopbits = 0; Timeout = 2000

3 modes are available: CONTINUOUS: the rotor rotates continuously OSCILLATION: the rotor oscilates RAMP: the rotor rotates continuously by speed steady period

Commands:

Name Description
StateInput: DevVoid
Output: State
This command gets the device state (stored in its device_state data member) and returns it to the caller.
StatusInput: DevVoid
Output: DevString
This command gets the device status (stored in its device_status data member) and returns it to the caller.
StartInput: DevVoid
Output: DevVoid
start the motor motion according to the operating mode selected (either CONTINUOUS or OSCILLATIONS) - CONTINOUS MODE: this is the write part of speed attribute which define the rotor speed once you push on start comand - OSCILLATIONS MODE: execute a sequence memorized in the controller (already programmed in the firmware)
StopInput: DevVoid
Output: DevVoid
stop the motor motion
PowerOFFInput: DevVoid
Output: DevVoid
cut the motor power
ResetInput: DevVoid
Output: DevVoid
the rotor returns to the default state (note that the encoder position is set to 0)
SendCommandInput: DevString
Output: DevString
send a specifc command to the specified controller. You must specify the controller adress in the string to send. adress list: 15: motor controller 03: temperature controller 02: torque controller ex: "15QX" where: 15 : the adress of the motor controller (2 bytes) QX: is the command (N bytes)
SetMotorParamInput: DevVoid
Output: DevVoid
Once you have written new values of speedMax, motorResolution, timeRamp attributes you must call setMotorParam(), thus new motor parameters are sent to the motorController
GetMotorParamInput: DevVoid
Output: DevString
get motor parameters
GetMotorStateInput: DevVoid
Output: DevString
return a message which inform you on the motor state
