Smartline V2 Transmitter Series
- class pymeasure.instruments.thyracont.smartline_v2.SmartlineV2(adapter, name='Thyracont SmartlineV2 Transmitter', baud_rate=115200, address=1, timeout=250, **kwargs)
Bases:
Instrument
A Thyracont vacuum sensor transmitter of the Smartline V2 series.
You may subclass this Instrument and add the appropriate channels, see the following example.
from pymeasure.instruments import Instrument from pymeasure.instruments.thyractont import SmartlineV2 PiezoAndPiraniInstrument(SmartlineV2): piezo = Instrument.ChannelCreator(Piezo) pirani = Instrument.ChannelCreator(Pirani)
- Communication Protocol v2 via RS485:
Everything is sent as ASCII characters
- Package (bytes and usage):
0-2 address, 3 access code, 4-5 command, 6-7 data length.
if data: 8-n data to be sent, n+1 checksum, n+2 carriage return
if no data: 8 checksum, 9 carriage return
- Access codes (request: master->transmitter, response: transmitter->master):
read: 0, 1
write: 2, 3
factory default: 4,5
error: -, 7
binary 8, 9
Data length is number of data in bytes (padding with zeroes on left)
Checksum: Add the decimal numbers of the characters before, mod 64, add 64, show as ASCII.
- Parameters
adress – The device address in the range 1-16.
- class Sources(value, names=None, *, module=None, qualname=None, type=None, start=1, boundary=None)
Bases:
IntEnum
- property analog_output_setting
Get current analog output setting. See manual.
- ask(command_message, query_delay=0)
Ask for some value and check that the response matches the original command.
- Parameters
command_message (str) – Access code, command, length, and content. The command sent is compared to the response command.
- ask_manually(accessCode, command, data='', query_delay=0)
Send a message to the transmitter and return its answer.
- Parameters
accessCode – How to access the device.
command – Command to send to the device.
data – Data for the command.
query_delay (int) – Time to wait between writing and reading.
- Return str
Response from the device after error checking.
- property baud_rate
Set the device baud rate.
- property bootloader_version
Get the bootloader version.
- check_set_errors()
Check the errors after setting a property.
- property device_address
Set the device address.
- property device_serial
Get the transmitter device serial number.
- property device_type
Get the device type, like ‘VSR205’.
- property device_version
Get the device hardware version.
- property display_data
Control the display data source (strict SOURCES).
- property display_orientation
Control the orientation of the display in relation to the pipe (‘top’, ‘bottom’).
- property display_unit
Control the unit shown in the display. (‘mbar’, ‘Torr’, ‘hPa’)
- property firmware_version
Get the firmware version.
- get_sensor_transition()
Get the current sensor transition between sensors.
- return interpretation:
- direct
switch at 1 mbar.
- continuous
switch between 5 and 15 mbar.
- F[float]T[float]
switch between low and high value.
- D[float]
switch at value.
- property operating_hours
Measure the operating hours.
- property pressure
Get the current pressure of the default sensor in mbar
- property product_name
Get the product name (article number).
- property range
Get the measurement range in mbar.
- read(command=None)
Read from the device and do error checking.
- Parameters
command (str) – Original command sent to the device to compare it with the response. None deactivates the check.
- property sensor_serial
Get the sensor head serial number.
- set_continuous_sensor_transition(low, high)
Set the sensor transition mode to “continuous” mode between low and high (floats).
- set_default_sensor_transition()
Set the senstor transition mode to the default value, depends on the device.
- set_direct_sensor_transition(transition_point)
Set the sensor transition to “direct” mode.
- Parameters
transition_point (float) – Switch between the sensors at that value.
- set_high(high='')
Set the high pressure to high pressure in mbar.
- set_low(low='')
Set the low pressure to low pressure in mbar.
- write(command)
Write a command to the device.
- write_composition(accessCode, command, data='')
Write a command with an accessCode and optional data to the device.
- Parameters
accessCode – How to access the device.
command – Two char command string to send to the device.
data – Data for the command.
