[Dsg-hallc_controls] Dipole Field Regulation PLC code completed

[Brian Eng]

BTW it looks like it lost the lock around 2300 last night. The dipole was ramped down?
I had left some code in that gives up trying to get a lock after 6 failed attempts (now commented out).

However now it seems like the PT2026 won't get a lock even though the dipole is at field.

I've tried both their Windows software and their bundled LabVIEW VIs.

Not sure what the problem is because it looks like the field is at ~1.8 T which is well within the range of the probe.
