Profile Components
The General Profile Configuration settings decide how profiles can be Run, Held or Aborted.
These settings apply to all profiles. Each profile has it’s own header information plus 1 or
more segments.
Profile Header & Segment Information
The profile header contains information about how the profile starts and stops, the power
loss recovery action and if it should repeat.
Note:
Profile Header information is stored to memory as the Segment creation sequence begins.
No profile is created if you exit before this point.
Segments can be ramps, dwells, steps or special segments such as holds, ends or joins.
Note: Segment information is stored as each segment is created, but the profile remains
invalid until an end or join segment is defined.
