There are five different types of segment:
Ramp The setpoint ramps linearly, from its current value
to a new value, either at a set rate (called ramp-rate
programming), or in a set time (called time-to-target
programming). You must specify the ramp rate or the
ramp time, and the target setpoint, when creating or
modifying a program.
Dwell The setpoint remains constant for a specified
period.
Step The setpoint steps instantaneously from its current
value to a new value.
Call The main program calls another program as a
subroutine. The called program then drives the
setpoint until it returns control to the main program.
This facility is available on those controllers with 4, or
20, stored programs.
End The program either ends in this segment, or
repeats. You specify which is the case when you
create, or modify, the program (see the final topic in
this chapter). When the program ends, the
programmer is put into either, a continuous Dwell
state with all outputs staying unchanged, or the Reset
state, or to a settable power level.
