May be we need just to reboot your box. What do you think?</div>

</div>
<div dir="ltr">I’m away from home now but I’ve been able to look at some of the RICH S1 things remotely. </div>
<div dir="ltr"><br>
</div>
<div dir="ltr">I can see that the two air flows, air pressure, and Nitrogen flow for RICH S1 are not updating. </div>
<div dir="ltr"><br>
</div>
<div dir="ltr">But, I can also see that the temperatures and humidities are updating for RICH S1. And I can see that there is air pressure and air flow from the buffer tank for S4. </div>
<div dir="ltr"><br>
</div>
<div dir="ltr">With this, I think there has been an issue with part of the S1 chassis (specifically the expansion cRIO) that is causing the issue.</div>
<div dir="ltr"><br>
</div>
<div dir="ltr">In reality, there is still probably airflow to S1, we just can’t monitor it currently. </div>
<div dir="ltr"><br>
</div>
<div dir="ltr">Im not able to come in right now. If the problem persists, I can come in later tonight or tomorrow. </div>
