Example Code/Wrappers

First, take a look at the AIN24 low-level documentation. The last 3-bytes in your response is the 24-bit reading as described in the 3-byte response part of that page. Convert those bytes to the 24-bit binary value, and then apply the appropriate calibration constants to get the voltage. So something like this with your response bytes to get the 24-bit value:

binValue = (bytes[11] << 16 ) + (bytes[10] << 8 ) + bytes[9]

For code on getting and applying the calibration contants that converts the binary value reading to a voltage, look at the getCalibrationData and binaryToCalibratedAnalogVoltage methods in the u6.py source code. Also, the Exodriver provides low-level example code which may be helpful.

We do not recommend talking to the device in multiple processes at once unless you have a particularly good reason to. That said, you could connect to the device in two separate processes if you use Ethernet connections. You can only obtain the USB connection in one process at a time, but you should be able to use USB in one program and Ethernet in another.

Our LJM library supports connection healing, so you should typically be able to start communicating with the device when the connection is restored. The following page has some recommendations for avioding LJME_RECONNECT_FAILED errors:

Another option could be to configure the software watchdog so that the device automatically restarts after a disconnect lasts a certain duration:
