Dear,
I'm starting to use python code to drive the Pxie-4139 board. I'm working on PXie-8821 with windows7 64 bit
I found this site https://pypi.org/project/nidcpower/ and install module and library.
This is an example code
import nidcpower
def example(resource_name, channels, options, voltage, length):
with nidcpower.Session(resource_name=resource_name, channels=channels, options=options) as session:
print(resource_name)
# Configure the session.
session.measure_record_length = length
session.measure_record_length_is_finite = True
session.measure_when = nidcpower.MeasureWhen.AUTOMATICALLY_AFTER_SOURCE_COMPLETE
session.voltage_level = voltage
print(session.get_channel_name)
session.output_function = nidcpower.OutputFunction.DC_VOLTAGE
session.current_limit = 100e-3
session.commit()
print('Effective measurement rate: {0} S/s'.format(session.measure_record_delta_time / 1))
samples_acquired = 0
print(' # Voltage Current In Compliance')
row_format = '{0:3d}: {1:8.6f} {2:8.6f} {3}'
with session.initiate():
while samples_acquired < length:
measurements = session.fetch_multiple(count=session.fetch_backlog)
samples_acquired += len(measurements)
for i in range(len(measurements)):
print(row_format.format(i, measurements[i].voltage, measurements[i].current, measurements[i].in_compliance))
options = {'simulate': False, 'driver_setup': {'Model': '4139', 'BoardType': 'PXIe', }, }
example('PXI1Slot2', '0', options, 3.0, 1)
And here the result
DriverError: -1074097933: Amount of time allocated to perform this operation was exceeded.
Information concerning the primary and secondary error codes has already been added to the error elaboration and therefore does not need further elaboration.
Amount of time allocated to perform this operation was exceeded
Probably there is an error with the library.
.
Any suggestion?
