<div>So far nothing seems incorrect, but hopefully we can remotely connect to the controllers to verify the settings are as described in S008 that Dave sent previously.</div>

<div>Just as a FYI the current controllers (TPG 256) are obsolete and have been replaced with TPG 336 which are ~2-3k each.<br>

Tyler and I met with Dave and Calvin to go over the issues.
<div><br>
</div>
<div>What we’ve found so far is that all of the vacuum pumps are only inputs into the PLC via the PointIO expansion chassis, i.e. no control at all via the PLC.</div>
<div><br>
</div>
<div>This means any issues with the controls is due to some other hardware (maybe those controllers? All the screens are dead/dying on them). Unfortunately the drawings I have quick/easy access to really only pertain to the PLC so it will take some more time
to dig up how anything outside of the PLC is wired/connected.</div>
