• 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. The values can be copied and pasted using
soft keys. Only the loops that are set as follows are displayed: [Control] > [#1 Control
action, Input setting] > [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 displayed 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 displayed only
during ramp in the segment time ramp 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 displayed
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 [Control]
> [#1 Control action, Input setting] > [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.
• Wait action
Set the wait action type to [Shift] or [Within]. To disable the wait action, select [Off].
• Wait zone number
Select the wait zone number from [1] to [5]. The entry box appears only when [Wait
action] is set to [Shift] or [Within].
Method of Confirming the Specified Program Pattern
In addition to confirming the settings of each segment on the program pattern setting
screen, you can also confirm the specified pattern on a line drawing by showing the
program control display as shown in the following figure. For the procedure in displaying
and operating the program control display, see section 6.4, “Operations on the Program
Selection Display/Program Control Display.”
