Explanation of 'Sometimes': Object 12 points are mapped to Virtual Inputs and Commands (Force
Coils). Both "Pulse On" and "Latch On" operations perform the same function in the 350 ; that is, the
appropriate Virtual Input or Coil is put into the "On" state. The On/Off times and Count value are
ignored. "Pulse Off" and "Latch Off" operations put the appropriate Virtual Input or Coil into the "Off"
state. "Trip" and "Close" operations both put the appropriate Virtual Input or coil into the "On" state if
a paired mapping is set, otherwise "Trip" will put into "Off" and "Close" will put into "On".
