[Dsg-hallb_magnets] [New Logentry] DBox PLC Download

Just as we were going down to Hall B to recover the Solenoid the DBox PLC stopped responding. All the EPICS values got disconnected and the PLC itself was indicating a fault (controller display was alternating between TEST & WAIT), so a slightly different (and worse) symptom from the Solenoid PLC.

Same as with the Solenoid PLC power was cycled and the code was downloaded to the controller. Dave and Denny verified PID settings.
