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 described in the operation manuals.
Before using the PT under conditions that are not described in the manual or applying the PT to nuclear control systems, railroad systems, aviation systems, vehicles, combustion systems, medical equipment, amusement machines, safety
equipment, and other systems, machines, and equipment that may have a serious influence on lives and property if used improperly, consult your OMRON representative.
Make sure that the ratings and performance characteristics of the PT are sufficient for the systems, machines, and equipment, and be sure to provide the systems, 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.
2General Precautions
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.
xii
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 correctly.
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 supplied.
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.
3Safety Precautions
If not backed up by the built-in battery, the memory switch settings will be initial-
ized to t h e v a l ues 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 replace 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 Nm 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.
xiii
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
2 mm
or greater cross sectional area and M 3.5 size crimp terminals must be
used. T ighten the screws on the terminal block to a torque of 0.8 Ncm. 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 effective 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 transmission, the screen data will not be correctly registered.
3Safety Precautions
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 activated.

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 elements, 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 allocated 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.

1-4-2 NT Link
Features of the NT Link
1-4SectionCommunications Using the Direct Connection Function
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-s e r i e s , C V M1 , C V-series, or SRM1 CPU Unit (built-in
Host 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.
S Controlling 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 statuses
S Notifying from the NT30/30C to a PC
Data in the NT30/30C is sent to a PC when a touch switch is pressed. The following 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
