Name Description
DecompressRateScalar: DevDouble Decompression rate set by the user. Used in conjunction with the Decompress Tango Device Command
SourceEffectivenessScalar: DevDouble Parameter reflecting effectiveness of the effort in order to achieve the setpoint
PressureControlScalar: DevBoolean Parameter controlling the main operation of the pump. If pressure control is ON – the device does it best to increase or decrease the pressure according to the setpoint. f pressure control is OFF – the device is going to the measurement mode, no control, just measurement (useful for leakage testing)
OvershootScalar: DevBoolean Parameter controlling the overshooting capability on pressure increase: 0 – not allowed 1 – allowed
SlewRateModeScalar: DevBoolean Instrumental mode for the slew rate operation – controls usage of the SlewRate parameter. Maximum slew rate – SlewRate parameter is disregarded and compression or decompression takes place with maximum pace. Linear – device respects the SlewRate setting and performs the compression or decompression accordingly
SlewRateScalar: DevDouble Slew rate for the output line pressure control
SetPointScalar: DevDouble Setpoint output line pressure
InletPressureScalar: DevDouble Current input pressure
MembranePressureScalar: DevDouble Current output pressure


Name Description
SendCmdInput: DevString
Command to send
Output: DevString
Return value in case it exists, empty string in other case.
Send command to pressure controller and return the answer in case it exits.
MakeHWTestInput: DevVoid
Output: DevLong
1-> OK, 0-> Fail
Performs a hardware test for the instrument. If the result is positive – device goes to the ON state, else, the device goes to the ALARM state and disallow any SCPI command to go through.
ClearErrorStateInput: DevVoid
Output: DevVoid
Clears the error state for the instrument. This is done by getting the GetErrorState – 5x times to clear the inner error message buffer
GetErrorStateInput: DevVoid
Output: DevString
Returns the error message from the instrument
GetMACInput: DevVoid
Output: DevString
Returns the MAC address from the device as a string
GetIDNInput: DevVoid
Output: DevString
Returns the identification string from the device as a string
CompressInput: DevVoid
Output: DevVoid
Starts the pump to do compression or decompression PressureControl = 1
DecompressInput: DevVoid
Output: DevVoid
Starts the decompression to the lowest pressure with DecompressRate First – stops the operation of the pump. Reads the value of the DecompressRate, sets the value of the SlewRate to this value Sets the SlewRateMode to 0=LINEAR Sets the SetPoint = 0 Sets the PressureControl = 1
StopInput: DevVoid
Output: DevVoid
Stops operation of the pump. The most important action – stop the PressureControl – power control – go to the measurement mode
StatusInput: DevVoid
Output: ConstDevString
Device status
This command gets the device status (stored in its device_status data member) and returns it to the caller.
StateInput: DevVoid
Output: State
Device state
This command gets the device state (stored in its device_state data member) and returns it to the caller.
