• 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.
