Pattern Initial Setting

Enter the program pattern number.
/PG1: 1 to 4, /PG2: 1 to 30

Select the time or ramp-rate (see below).

Enter the pattern name (up to 16 characters).

Enter the number of segments to be used.
1 to 99

Specify the position of the segment to be
deleted or added.

Rate-of-change

Target SP

Segment time

Minute or hour

Method for creating the segment
using the target SP and the
ramp-rate of the SP change.
Set the ramp-rate using rate-of-
change per minute (example:
2

C per minute) or rate-of-change

per hour (example: 10

C per hour).

Method for creating the
segment using the target
SP and the segment time.

Segment setting method: Time

Segment setting method: Ramp-rate

Target SP

Wait Action Setting

Set 5 types of wait actions. Specify the wait action for each segment.

Select [On] to set a wait zone.

Wait zone number

Enter the maximum wait time when using the
wait function at the time of segment switching
(see below).

Set the wait zone (engineering unit).

Wait zone High

Wait zone Low

Wait function at the time of segment switching

If the PV is outside the wait zone when the SP reaches the target SP
of the segment, the program does not advance to the next segment.
When the PV enters the wait zone, the program advances to the next
segment. In addition, when the wait time elapses even if the PV does
not enter the wait zone, the program advances to the next segment.
If the wait zone is set to 00:00:00, the program does not advance to
the next segment until the PV reaches the wait zone.

Segment 1

Segment 2

Wait zone high

Wait zone low

Wait zone high

Wait zone low

Wait time
(specified value)

Actual wait time

Wait function within the segment

The advancing of the program control stops when the SP exits from
the wait zone. When the PV returns within the wait zone, the
advancing of the program control resumes. [Segment time] setting
is irrelevant for wait within the segment. The advancing of the
program control is stopped until the PV reaches the wait zone.
