• 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. On Style 3 or later, the value can be set on

the loop whose Action Loop Set is ON. On Style 2 or earlier, the value can be set on

loops whose [Control Mode] has been set to a mode other than [Off] and [Program

Control] to [On] in [Internal Loop] under the [Setup] tab. During cascade control,

even-numbered loops within the same terminal block cannot be set.

• 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.

• Segment shift action

Set the segment shifting action to [Continue], [Hold] (hold after end of segment),

[Local] (local mode after completing the last segment), or [Reset] (reset mode after

completing the last segment).

Note

When creating the program pattern, data is created so that the segment set to [Local] or [Reset]

is the last segment of program control.
