edge of electrical systems (an electrical engineer or the equivalent).
Personnel in charge of installing FA systems.
Personnel in charge of designing FA systems.
Personnel in charge of managing FA systems and facilities.
2 General Precautions
The user must operate the PT according to the performance specifications de-
scribed in the operation manuals.
Before using the PT under conditions that are not described in the manual or ap-
plying the PT to nuclear control systems, railroad systems, aviation systems, ve-
hicles, combustion systems, medical equipment, amusement machines, safety
equipment, and other systems, machines, and equipment that may have a seri-
ous influence on lives and property if used improperly, consult your OMRON rep-
resentative.
Make sure that the ratings and performance characteristics of the PT are suffi-
cient for the systems, machines, and equipment, and be sure to provide the sys-
tems, machines, and equipment with double safety mechanisms.
This manual provides information for using the Programmable Terminal. Be sure
to read this manual before attempting to use the software and keep this manual
close at hand for reference during operation.
If a faulty PT is returned for repairs, write as detailed a description of the fault as
possible and send the description together with the PT to the OMRON address
indicated on the back cover of this book.
When disposing of an NT that is no longer required, be sure to comply with all
local restrictions that apply to its disposal.
WARNING It is extremely important that Programmable Terminals and related devices be
used for the specified purpose and under the specified conditions, especially in
applications that can directly or indirectly affect human life. You must consult
with your OMRON representative before applying Programmable Terminals to
the above mentioned applications.
WARNING Do not use input functions such as PT touch switches for applications where
danger to human life or serious damage is possible, or for emergency switch
applications.

3 Safety Precautions
Read these safety precautions carefully and make sure you understand them
before using the Programmable Terminal so that you can use it safely and cor-
rectly.
WARNING
Never attempt repairs, modification or disassembly. You could sustain an elec-
tric shock.
Switch OFF the PT power before changing the backlight. You could sustain an
electric shock if you attempt to change the backlight while power is being sup-
plied.
Caution
When disposing of a used backlight, comply with all local restrictions that apply
to its disposal.
When replacing the battery, do not allow the battery terminals to touch the
board in the PT.
If not backed up by the built-in battery, the memory switch settings will be initial-
ized to the values set with the NT-series Support Tool when the power is turned
OFF. If a message indicating that the battery is low is displayed while the PT is
being used, replace the built-in battery immediately. For details on how to re-
place the battery, refer to Replacing the Battery (page 253).
Switch OFF the power supply to both the PT and the B7A Interface Unit before
installing the B7A Interface Unit, otherwise the PT or the B7A Interface Unit
may be damaged.
Switch OFF the power supply to both the PT and the B7A Interface Unit before
changing DIP switch settings.
Do not use input functions, such as PT touch switches, for applications where
danger to human life or serious property damage is possible or for emergency
switch applications.
Do not use the expanded I/O functions of the B7A Unit for applications where
danger to human life or serious property damage is possible or for emergency
switch applications.
On unpacking the PT, check its external appearance and confirm that there is
no damage. Also confirm that there is no abnormal noise on shaking the PT
lightly. The PT may malfunction if it is damaged.
During work at the panel, be sure that no metal scraps enter the PT. Otherwise,
the PT may malfunction.
The thickness of applicable operation panel is 1.6 mm to 4.8 mm. All fittings
must be tightened uniformly to a torque of 0.5 to 0.6 Nm in order to ensure
water- and dust- resistance. The panel must not be soiled or warped, and must
be able to support an installation that will remain secure and strong.
Carefully check wiring before switching ON the power.

3Safety Precautions
xiv
Do not apply an AC power supply across the power supply terminals.
Use a DC power supply with a low voltage fluctuation.
When complying with EC low voltage directives use a power supply with rein-
forced insulation.
For the connection to the power supply terminal block, twisted-pair wires with a
2 mm2or greater cross sectional area and M 3.5 size crimp terminals must be
used. Tighten the screws on the terminal block to a torque of 0.8 Ncm. Other-
wise fire may occur.
If the DIP switch settings have been changed while power was supplied to the
PT, reset the power to the PT. The changes with the DIP switch become effec-
tive only after the power supply is reset.
Before switching ON the power for the first time, set pin 6 of DIP switch SW2 on
the PT to ON (it is set to OFF on shipping). If it is left OFF, messages will not be
displayed normally.
Press the Abort touch switch on the PT when screen data transmission has
been completed. Unless this touch switch is pressed, the screen data will not
be correctly registered. If the Abort touch switch is pressed during transmis-
sion, the screen data will not be correctly registered.
Check the operation of screen data and ladder program thoroughly before ac-
tually using them.
Press touch switches with a force of no greater than 30 N. Applying higher force
may cause glass to break, resulting in injuries or preventing operation.
Do not press touch switches carelessly while the backlight is OFF or while
nothing is displayed on the screen. The system may operate unpredictably.
Press touch switches only after confirming system safety.
As far as possible, disconnect all devices connected to the output terminals be-
fore executing the output check. Otherwise, each time an output terminal
comes ON during the check operation, the outputs to the devices may be acti-
vated.

Character strings stored in the character string memory table can be dis-
played. The display characters can be changed by changing the data stored in
the character string memory table.
Numeric Values (Numeral Memory Table)
Numbers stored in the numeral memory table can be displayed. The display
numbers can be changed by changing the data stored in the numeral table.
Hexadecimal values can be displayed.
Lamps Lamps can be used to indicate operating status. Squares, circles, fans, and
polygons can be used. They are controlled by the PC and can be lit (reversed)
or made to flash (alternates normal and reversed displays).
Touch Switches Touch switches can be set anywhere on the screen. Pressing the part of the
screen where a touch switch has been set can have the following effects: Noti-
fication of the fact that the switch has been pressed to the PC (PC notification
function); screen switching; input of a numerical value or character string (input
key function); copying of a numerical value or character string (copy key func-
tion); shifting to another numerical value or character string input field (cursor
moving key function); and obtaining a hard copy of the screen (screen print key
function). Touch switches are controlled from the PC and can be made to light
or flash in the same way as lamps.
Graphs Bar graphs, trend graphs, and broken line graphs can be displayed according
to the numerical values stored in numeral memory table. These values can
also be represented as percentages displayed together with the graphs.

1-4 Communications Using the Direct Connection Function
1-4-1 Direct Connection Function
The communications method applied between the NT and the PC is either a Host
Link or NT Link.
The NT30/30C can be used to access data for the display or to allocate the bits
and words for storing input data in essentially any area in the PC. The NT30/30C
can directly write and read the allocated bits and words to change the display ele-
ments, control operating status, and notify status.
This function is called the direct connection function. The NT30/30C is designed
specially for use with a direct connection.
The bits and words allocated by the direct connection function are called allo-
cated bits and allocated words.
A direct connection enables reading the data to be displayed on the NT30/30C
from a memory area in the PC and writing it to a memory table in the NT30/30C.
Also, the data input at the NT30/30C can be written to a PC memory area. The
NT30/30C screen status can be switched according to PC memory area data,
and NT30/30C status data can be written to a PC memory area.

DM Area IR/CIO Area
AR Area Timer/Counter
Area
Features •The bits and words used to access operating status and work instructions and
those for storing input data can be allocated in almost any part of PC I/O me-
mory. Bits and words in the PC are accessed from memory table entries.
•The NT30/30C can directly access PC bit and word data so that it can be con-
nected to a PC without changing the PC program that controls the current pro-
duction line.
•The area to control and notify the NT30/30C status, including display screens,
display/no display status, and buzzers, can be allocated in almost any part of
PC I/O memory.
The direct connection function allows the NT30/30C to directly read and write al-
most all bits and words in the PC and to automatically change the NT30/30C
screen display. This function can reduce the load on the PC to improve the pro-
gram development efficiency of the PC.

1-4SectionCommunications Using the Direct Connection Function

1-4-2 NT Link
The NT Link is a new communications method between the PT and a PC.
The NT Link uses the direct connection function and can execute high-speed
communications with a CPM1, CPM2A, CPM2C, CQM1, CQM1H, C200HS,
C200HX/HG/HE(-Z), CS1-series, CVM1, CV-series, or SRM1 CPU Unit (built-in
Host Link).
Features of the NT Link •High-speed communications with specific types of PCs can be executed.
•Writing in units of bits to the PC memory area is possible (except the DM Area.
.This enables the bit in a word data to which a touch switch has been allocated
to be used for other purposes (e.g., to control a lamp).
•This can be used even when the PC is in RUN mode. (With Host Link, if the PC
is in RUN mode, the NT30/NT30C switches the mode to MONITOR mode.)
Either the NT Link or the Host Link can be used for connection without changing
the NT30/30C screen data or the PC program.
1-4-3 Functions of the Allocated Bits and Words
Elements displayed on the NT30/30C and the NT30/30C status can be allocated
to the bits and words of the PC. By changing the contents of the bits and words,
the NT30/30C can be controlled by the PC. It is also possible to send data to the
PC by pressing the touch switches on the NT30/30C.
SControlling the NT30/30C by a PC
The following NT30/30C functions can be controlled by a PC.
Screens: Display of designated screens, confirmation
of screen numbers, etc.
Memory tables: Writing to a memory table entry, copying from
a memory table entry to another memory
table entry, etc.
Lamps and touch switches: Display instructions, confirmation of display
status, etc.
System control: Buzzer ON/OFF, display/no display status,
screen printing, and other NT30/30C sta-
tuses
SNotifying from the NT30/30C to a PC
Data in the NT30/30C is sent to a PC when a touch switch is pressed. The fol-
lowing types of data can be sent to the PC.
•NT30/30C status
•Touch switch status
•Numeric values and character strings input with numeral/character string
setting functions using touch switches.
•Changes in a memory table entry after copying between memory table en-
tries
