Dear Tyler,</div>

There will be a 20-30 minute access opportunity around noon today (for ECAL work). I'm not sure if that's enough time to take a look at the cRIO, but it is an access opportunity.</div>

Also, I noticed that some of the S4 PVs, namely airflow, air pressure, and N2 flow, look like they are frozen; the heartbeat is beating though.</div>
