1 Intended Audience
This manual is intended for the following personnel, who must also have knowledge 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 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.

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
Page 10
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.

• 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 memory. 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 connected to a PC without changing the PC program that controls the current production 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.
Timer/Counter

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

2-6 Connection to a PC by Host Link via RS-422A
Connect the NT30/30C to an OMRON PC by using the RS-422A Host Link method.
If the distance between the NT30/30C and the PC is greater than 15 m, this method should be used. The maximum distance over which a connection can be
made is 500 m.
When using the RS-422A method, the host computer and PC are usually connected in a 1 to N r a t i o ( m o r e t han one PC), but in the special case of the connection between the NT30/30C and PC, the ratio is 1 to 1.
In order to make a connection to the PC using the Host Link method (RS-422A),
the host communications memory switch of the NT30/30C must be set to Host
Link, and the port memory switch must be set to RS-422A. For details on memory
switch settings, see Selecting the Host Communication Method (page 85) and
Selecting the Host Link Communication Port (page 87).
The terminating resistance setting on the NT30/NT30C (DIP switch 2 pin 8) must
also be set to ON.

Reference
2-6-1 Compatible PCs
Some models and series of OMRON PCs have the Host Link function built in.
Check the model and series of the PC and the model of the Board or Unit before
making the connections.
The Units that can be connected to the NT30/NT30C’s RS-422A port as the host,
and have RS-422A Host Link functionality are listed in the table below.
By using the NT-AL001 RS-232C/RS-422A Link Adapter, it is possible to con-
nect the RS-422A terminal block of the NT30/NT30C to the RS-232C connector of the CPU Unit, Host Link Unit, or SRM1. In this case, set the communications method for the NT30/NT30C to RS-422A and the communications
method of the PC to RS-232C. For details of the connection method, refer to
the manual provided with the RS-232C/RS-422A Link Adapter.
It is not possible to connect the NT30/NT30C to the PC using RS-485 (2-wire)
Host Link communications.

3-4-3 Initialization of the Display History Data Memory
The display history function is a function whereby the display of each screen displayed during operation is recorded in order of display occurrence and order of
display frequency. The maximum number of displays that can be recorded is
1,023 for recording in order of display occurrence and 255 for recording in order
of display frequency. Once these limits are reached, no more records can be
stored, and so the records must be periodically initialized (deleted).
The display history data memory can be initialized by a command given from the
PC (page 241).

This section describes the communications condition settings by using the
memory switches.
Memory Switches The NT30/30C has the memory areas used to store the PC connection method,
communications conditions, system settings, etc. that can be used as the
switches and called the memory switches. Since the memory switch settings are
backed up by battery, they are not lost when the power is turned OFF.
Reference
If the memory switch data is not backed up by the built-in battery, it will all be
initialized to the values set with the NT-series Support Tool when the NT30/30C
is switched OFF.
If the message “Battery Lowered” is displayed while the NT30/30C is operating,
replace the built-in battery immediately. For details on how to replace the battery, see Replacing the Battery (page 253).

3-6 Registering the Screen Data
The screen data is created by using the NT-series Support Tool and registered to
the NT30/30C screen data memory. This section describes the procedure to register the screen data to the NT30/30C. For the screen data creation and NT -series Support Tool operation, refer to the NT-series Support Tool Operation Manu-
al.
Transmission – Transmission in File Units
The NT30/30C uses several screens that are switched on its display. The screen
data of one NT30/30C PT corresponds to the files created by using the NT-series
Support Tool. Select a file that contains the screen data to be transmitted when
selecting the screen data to be transmitted to the NT30/30C so that the required
screen data can be transmitted to the NT30/30C.

Direct information
When the screen data is transmitted from the NT-series Support Tool to the
NT30/30C, the s c r een data already existing in the NT30/30C will be erased. Th e
NT30/30C cannot transmit the screen data in units of screens.
If an error message and the System Menu are displayed immediately after the
NT30/30C has been started, the screen data memory needs to be initialized.
Transmitting the Screen Data from the NT-series Support Tool
To transmit the screen data from the NT-series Support Tool to the NT30/30C,
connect the NT30/30C to the computer on which the NT-series Support Tool is
being used, and follow the procedure below.
Reference
When screen data transmission is performed, the NT30/30C screen data
memory is automatically initialized before the new screen data is transmitted.
There is therefore no need to initialize the screen data memory using menu
operations before transmitting the screen data.
The NT30/30C uses the same connector for screen data transfer and
RS-232C connection to the PC. If this connector is currently being used for
RS-232C connection to the PC, disconnect the cable from the PC, connect it to
the NT-series Support Tool (personal computer), then transmit the screen
data.

Precautions to be Observed During the Screen Data Transmission
Press the Abort touch switch on the NT30/30C when the screen data transmission is 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.
If screen data cannot be transmitted from the NT-series Support Tool properly,
check whether communication between the NT30/30C and NT-series Support
Tool (personal computer) is normal.
When any of the following or a system error occurs during the screen data transmission, the transmitted screen data will not be registered correctly to the
NT30/30C. If an error message is displayed and the Run Mode cannot be selected, the screen data memory needs to be initialized.
• The power to the NT30/30C is interrupted or the NT30/30C is reset.
• The power to the computer on which the NT-series Support Tool is running is
interrupted or the computer is reset.
• The cable connecting the NT30/30C to the computer on which the NT-series
Support Tool is running is disconnected or has a broken wire.
• The Cancel touch switch on the NT30/30C screen is pressed to end the transmission during screen data transfer.
• The Cancel button on t h e N T-series Support Tool is pressed to end the transmission.
When the power to the NT30/30C is turned ON or reset, the screen data is
checked. However, i f any of the above occurs during the screen data transmission, the screen may disappear and other unexpected problems may occur.
In the case of such problems, set DIP switch SW2 pin 4 to ON to initialize the
memory.
For the memory initialization by using the DIP switch, refer to the Initialization by
Using the DIP Switch (page 80).
