Displayed Preset Pattern Waveforms and Their Display Color
Only the preset pattern waveforms of 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]. If cascade control loops are present, the secondary loops
are not displayed. The pattern waveform colors are red, green, blue, blue-violet, brown,
and orange for loops 1 to 6, respectively.
Turning ON/OFF Preset Patterns and PV Waveforms
If viewing is difficult due to overlapping waveforms or if you wish to monitor only certain
loops, you can turn OFF the display of unneeded waveforms. For loops of which the
waveform display is turned OFF, the background color (waveform color) of the tag/tag
comment display in the numeric display section disappears.

No background color
Split Waveform Display on the Program Selection Display and Program Control
Display
If viewing is difficult due to overlapping waveforms on the full display, you can divide the
display area into sections. The waveform display position of each loop in split display is
set using [setting mode (control)] > [#7 Program-control parameters] > [#3 AUX (Auto
message, Display position)] > [Program display position]. For the procedure, see section
5.9, “AUX (Auto message, Display position).”
The figure below shows an example in
which the display area is divided into three sections.

Note
The scale displayed at the right edge of the waveform display section on the full display is the
scale corresponding to the smallest numbered loop. On the split display, the scale is that of
the smallest numbered loop in the divided area.
Changing the Pattern Settings When in Hold Operation
You can change the following settings when in hold operation.
• The remaining time of the current segment
• Target SPs of each loop
When in hold operation, the soft key menu shows [SEG TIME] (display a window for
changing the remaining segment time) and [TSP CHG] (display a menu for selecting the
loop of which the target SP is to be changed).
