• Ramp/Soak select

Select the type of segment to be specied ([Ramp] or [Soak]).

• Target setpoint (ramp segment only)

Set the nal 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 specied. 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 specied 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.
