The noise eater switch is not toggling.  This was checked by:
 - measuring the NPRO power noise out to 1 MHz
 - measuring the voltage across the connector at the front panel of the control box, which is effectively the output
     of the KL2612 terminal

    TwinCAT recognises a change of state when one is requested.

Update
    The cable from the NPRO power supply was modified.  Remote operation of the noise eater is now possible.  On the
FSS MEDM screen, on the left hand side there are two buttons ON (green) and OFF (red) and an indicator next to the
"NPRO RRO:NOISE EATER" indicator.  These two buttons operate the noise eater.  If it's on the indicator to the right
of the two buttons is green.  Off, red.
