Screens with predetermined functions are called system screens.
The types of system screens are indicated in the table below.
Screen

Name
Function
0
No-display screen
If screen number 0 is designated as the display screen, the screen of the PT is made
blank.
9000
System initializing
screen
This screen is displayed during the initial processing when the PT starts operation.
During operation, screen number 9000 cannot be designated for display, but it is pos-
sible to create and register a screen under screen number 9000 at the Support Tool,
and this screen can then be displayed instead of the default system initialization
screen. Only fixed display elements can be registered for screen number 9000.
9001
Occurrence history
screen
The PT features the display history record function. which records the display status
of screens. By designating screen number 9001 as the display screen, you can
check the screens that have been displayed up to the present time in display order.
You can set whether the records are presented in the order of newest first or oldest
first by setting a PT memory switch.
9002
Frequency history
screen
The PT features the display history record function. which records the display status
of screens. By designating screen number 9002 as the display screen, you can
check the screens that have been displayed up to the present time in order of fre-
quency of display.
9020
Programming Con-
sole function
screen
As an expansion function, the PT features the Programming Console function, which
allows equivalent functions to those of a Programming Console. When the PT is con-
nected to a host which supports the Programming Console function, it can be used in
the place of a Programming Console by designating screen number 9020 as the dis-
play screen.
9021 to
9023
Device Monitor
function screens
The PT has been equipped with the Device Monitor function, which can perform the
same functions as a Data Access Console (DAC). When the PT is connected to a
host that supports the Device Monitor function, one of the following screens can be
specified to list the contents of host words, change word PVs, or display error log
information.
9021:

ment Screen
This screen can be used to adjust the contrast and the backlight brightness during
PT operation.
9999
Return to previous
screen designation
In addition to the display history function, the PT has a function which allows the
screen numbers of up to 32 screens to be recorded in their order of display. When
screen number 9999 is designated as the display screen, the screen that was dis-
played immediately before the currently displayed screen is redisplayed. However,
note that if a system screen is displayed in the middle of operation, the record of dis-
played screens is cleared. (The display history function’s data is not affected.)
