Segment can be used in a profile, but they must not cross.

Figure 40. Run/Hold & Hold Segments
A Hold during a segment maintains the current setpoint value. Once the hold is stopped the
Ramp or Dwell continues. Depending on the configuration, a hold can be the started &
stopped by via a key-press, breaking the signal to a Run/Hold digital input, a serial comms
command or by the Auto-Hold feature (see below).
Note:
A running profile will also hold while Manual Control is selected.
A Hold Segment is a pre-planned hold, programmed into the profile. It maintains the value of
the previous segment. The profile does not continue until a Continue Trigger occurs. This
can be via a key-press, a digital input signal or after waiting for a time of day (available on
Recorder version only).
