I can give you the array of the 60 values that are passed between the PLCs, problem is I don't know what if any are used in PID loops.

Hi Eugene,
I'm looking into the possible effect of the "not talking" signals.


Brian,
What signals from the solenoid are not updating in the Torus (DBX) PLC?

I see at some that are updating:
 DP8620VCLDP

B_TORUS:LHe:PV8522SR:CVAL  = PT8620
B_TORUS:LHe:PV8522SCD_Min_Min:CVAL = LL8620

Thanks Guys
Dave

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
