It will connect to the ~100 PVs on the master controller IOC and also to the corresponding ~100 PVs on the power supply IOC.  When the user presses a Copy button the SNL program copies the values from the master controller IOC to the power supply IOC.

Using a set of 'seq' records could accomplish the same thing w/ a
special SNC program.
