• Ramp/Soak select
Select the type of segment to be specified ([Ramp] or [Soak]).
• Target setpoint (ramp segment only)
Set the final SP of the ramp segment in the range of “EU (0.0% to 100.0%)” (initial
value is 0%) of the measurement span. For style 3 or later, the target setpoint setting
for loops turned ON in operating loop designation can be entered. With style 2 or
earlier, settings for loops turned ON in Program Control under Internal Loops in the
Setup tab can be entered. Only the loops that are set as follows are available: [Setup]
tab> [Internal Loop] > [Control mode] to a mode other than [Off] and [Program control]
to [On] During cascade control, even-numbered loops within the same terminal block
are not displayed.
• Segment time
Set the segment time in the range of [0:00:01] to [99:59:59] (0 hour 0 min 1 s to 99
hour 59 min 59 s). This item is available at all times during segment time setting
method and only when soak is selected during segment time ramp setting method.
• Ramp-rate time unit
Set the ramp-rate time unit for ramps to [Hour] or [Minute]. This item is available only
during segment time setting method.
• Ramp
Set the ramp per unit time in the range of “1 digit to EUS (100%) of the measurement
span.” The measurement span and decimal point position of the selectable range
vary depending on the smallest numbered loop to be specified. This item is available
only during ramp in the segment time ramp setting method.
• Segment PID group No.
Select the segment PID group number [1] to [8]. This item is not displayed when zone
PID is selected. Only the PID group numbers that can be specified through [Setup]
tab > [Control action] > [PID number] are displayed.
