Tsuneo and Phillip, unless the target pressure issue has been resolved, the cell membrane, gas panel valve seals, and internal plumbing integrity need to be verified. Please coordinate with Denny to pick up the Target from the top ISO Flange with the gantry
in the ESB (there are three lifting eyes). Rigging should be one sling (down stream) and two come-alongs (up stream) to level the flange before lifting. When it's lifted I can help with shield removal and the cell inspection. Just let me know when.</div>

After the inspection, the flow tests need to be made again. Hopefully it will reproduce the measurements made in 2015 and the modifications Bob planned can proceed. The schedule he presented in June had the target modifications completed at the end of this
month. These changes can't proceed until the testing is complete. </div>

Tsuneo and I tested the control and position readback of EV1, EV2 valves using LabVIEW PRad program, and noticed no issues. You might want to test the status readback for the Gate Valve and Vacuum Switch later when running the system. Fixing the readout issues

Pablo, I found two Datexel Modbus Daq modules that should cover everything that needs to be read out for PRad II. It might be faster to use these we have onhand. Chris Carlin may have a quick solution or daq from NI that could work as well. The bottom line
is the target controls needs to be sorted out asap. Here are the link to the datasheets.</div>

The AIO com error indicator that you show in the attached screenshot is assigned to check the comms with the 6001 USB-DAQ device which is used to read analog and digital signals, we are aware that the 6001 module has issues with its DI channels, as you will
notice the EV1 and EV2 indicators do not change to open even when we checked that the valves are physically opened. Also, the vacuum switch or turbo pump enable status don't work, only the AI channels to read the pressure for the Bottle and Cell/Chamber are
working.</div>

I tried to help Wei with the PRad II ESB Tests but was unable to do so. The LabVIEW vi you wrote for PRad II is having communication errors causing it to stop working. The COM ERROR labeled as AIO repeatedly and randomly presents an error. I'm not sure if
it's an issue is with address ports assigned to the USB to RS232 box or some latency com issues with AIO but it needs to be addressed and corrected. The PRad test needs to be concluded for other modification to take place and time is running out. I can meet
you out there to perform a quick room temp flow measurement using your program so we can identify the problem and fix it. When are you avaiable? </div>
