[Hallb-engineering] DP8620VCLDP

[Eugene Pasyuk]

If it can wait until tomorrow, then we can ramp magnets down and safely reboot it during the pass change tomorrow morning.

So I poked at the tags some more and it turns out that this one is updated on the DBox PLC, which I can still connect to. So I manually reset the error bit and this value is now updating on the PID screens.

caget B_TORUS:LHe:PV8522SR_Val:CVAL.INP
B_TORUS:LHe:PV8522SR_Val:CVAL.INP @PLC_CRYO PV8522SR_Val.CVAL

The torus PLC still isn't seeing updating values from the solenoid, but maybe we can put off the reboot until tomorrow?

Just as a reminder,
This signal is a calculated value base on two pressure sensors.
the math goes as follows:

DP8620VCLDP =PT8620-PT8571

There is a similar setup of
DP8670MAGDP = PT8670-PT8571
