Direct Connection Function
1-5
Section 1-5
Direct Connection Function
The communication method applied between the NT11 and the PLC is either
a host link or NT link.
The NT11 can be used to refer to the contents necessary for the display information or to allocate the bits and words used for storing the input data to any
area in the PLC. The NT11 can directly write and read such allocated bits and
words so as to change the display elements, control the operating status, and
notify the status.
This function is called the “direct connection function”. The NT11 is designed
exclusively for use with the direct connection.
The bits and words allocated by the direct connection function are called “allocated bit” and “allocated word” respectively.
This function allows to read the information to be displayed on the NT11 from
the memory area in the PLC and to write it to the memory table in the NT11.
Also, the data input on the NT11 can be written to the PLC’s memory area.
The NT11 screen status can be switched according to the PLC’s memory
area, and the NT11’s status data can be written to the PLC’s memory area.
NT11
PLC
Data memory area
Internal relay area
Auxiliary relay area
Timer/counter
Features of the Direct Connection Function
• The bits and words referring to operating status and work instruction information and those for storing input data can be freely allocated to almost
any part of the PLC memory. Bits and words in the PLC can be referenced from any memory table.
• The NT11 can directly refer to PLC bit and word data so that it can be
connected to a PLC without changing the PLC program which controls
currently running production line.
• The area to control and notify the NT11 status, including display screens,
ON/OFF of the backlight, and printing of daily reports and display histories, can be freely allocated to any part of the PLC memory.
The direct connection function allows the NT11 to directly read and write
almost all bits and words in the PLC and to automatically change the NT11
screen display. This function can reduce the load on the PLC so that the program development efficiency of the PLC improves.
1-5-1
NT Link
The NT link is a new communication method applied between the NT11 and a
PLC.
The NT link uses the direct connection function and can execute high speed
communications with a CPU (built-in NT link) of the CQM1, C200HS, and
other PLCs.
Features of the NT Link
• High speed communications with specific types of PLCs can be executed.
• Writing in units of bits to the PLC memory area is possible. (*)
9
Direct Connection Function
Section 1-5
• This can be used even when the PLC is in the RUN mode.
(*) Except a DM area.
The NT link is compatible with the host link. The NT11 screen data and the
PLC programs handled by the host link direct connection can be used with for
the NT link as they are.
1-5-2
Functions of the Allocated Bits and Words
Elements displayed on the NT11 and the NT11 status can be allocated to the
bits and words of the PLC. By changing the contents of the bits and words, the
NT11 can be controlled by the PLC. It is also possible to send data to the PLC
by pressing the function keys on the panel of the NT11.

CVM1/CV-series Rack-mounted Unit: CV500-LK201
A CVM1/CV-series Host Link Unit (CV500-LK201) has two connectors (communication ports 1 and 2). Either of these ports can be used for connection to
an NT11 by the RS-232C method. However, since the connectors at these
ports are of different types, a cable that matches the connector must be prepared.
• Communication port 1
Communication port 1 is a 25-pin connector for RS-232C use only.
• Communication port 2
Communication port 2 is a 9-pin connector that allows selection of the
RS-232C or RS-422A method. When this port is used with the RS-232C
method, the I/O port selector switch on the front of the Unit must be set to
RS-232C (the upper position).

Connecting to a CPM2C
The CPM2C PLCs do not have the same kind of port connectors found on
CS1-series PLCs. The CPM2C’s communication port handles both RS-232C
and peripheral port connections, which are divided internally. Therefore, when
using the CPM2C, it is necessary to select RS-232C or peripheral port connections, according to the kind of cable and port (on the cable) used, as
shown in the following table. Refer to the CPM2C Operation Manual for more
details.

Connection to a PLC by the Host Link (RS-422A Type)
Connect the NT11 to an OMRON PLC by using the RS-422A type host link
method.
If the distance between the NT11 and the PLC 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 PLC are usually
connected in a 1 to N ratio (more than one PLC), but in the special case of the
connection between the NT11 and PLC, the ratio is 1 to 1.
In order to make a connection to the PLC using the host link method (RS422A type), the “Comm. Type” memory switch of the NT11 must be set to the
host link, and the “Comm. Port” memory switch must be set to RS-422A. For
details on memory switch settings, refer to 3-7-1 Selecting the Host Communication Method (page 73).

Compatible PLCs
When Using the Host Link Method
Compatible Host Units
Some models and series of OMRON PLCs have the RS-422A type Host Link
function built in. With a CS series, CJ series, and CQM1H Board or Unit, and
CQM1H, the Host Link method can be used by installing a Serial Communications Board. In addition, some C200HX/HG/HE(-Z)E devices have an integral
CPU Unit that can be connected in the Host Link method by installing a Serial
Communications Board.
With the CPM2A and CPM2C, an RS-422A type of 1:1 NT Link can be connected through a CPM1-CIF11 RS-422A Adapter.
Check the model and series of the PLC and the type of the installed Board or
Unit before making a connection.

occur.
In the case of such problems, set DIP-SW2-2 to ON to initialize the memory.
For the memory initialization by using the DIP switch, refer to 3-4-2 Initialization by Using the DIP Switch (Forced Initialization) (page 65).
3-7
Setting the Conditions of Communications with the PLC
by Using the Memory Switches
The communications between the NT11 and a PLC are called the host communications.
The NT11 can be connected to a PLC by the host link or NT link. The link can
be selected by setting the memory switch. Also, the host link baud rate, automatic reset function, etc. are set with the memory switches.
This section describes the communications condition settings by using the
memory switches.
Memory Switches
The NT11 has the memory areas used to store the PLC connection method,
communications conditions, system settings, etc. which can be used as the
switches and called the “memory switches”. Since the memory switches use
the flash memory, the stored data can be held even when the power supply is
turned OFF.
Setting Functions and the Memory Switch Menu
The memory switches can be set easily by using the memory switch menu in
the System Menu.
The following settings can be made with the memory switches. Refer to the

refer to 6-2 Responding to Displayed Error Messages (page 138) and take
appropriate action.
Confirming the Communications between the NT11 and the PLC
Execute the PLC program and confirm that the following operations are normally performed.
• Confirm that the NT11 screens switch according to the PLC program execution.
If the screens do not switch correctly, check the connection between the
NT11 and the PLC and also check the settings.
Refer to SECTION 2 Hardware Settings and Connections.
• Confirm that the information selected by the NT11 function keys has been
set in the PLC by displaying the contents of the words and bits using a
peripheral tool (CX-Programmer etc.). If the information sent from the
NT11 has not been correctly received by the PLC, check the screen data
settings (specifically the switch settings).
For the details of the screen data creation, refer to the NT-series Support
Tool Operation Manual (V061-E1-1).

Screen Attributes
Assigning an attribute to a screen makes it capable of a special function when
it is displayed. For example, when an attempt is made to display a screen for
which the “password” attribute is set, a message requesting input of the password will be displayed and the specified screen will not be displayed until the
password has been input.
Set screen attributes for each screen by using the “screen selection” screen
of the support tool.
It is possible to set more than one of the following attributes for a screen.
Numeral setting attribute
This attribute makes it possible to use numeric keys on the panel of the NT11
to input numerical values on screens on which numerical values have to be
set.
For numeral setting, the write channel, display position, and display method
must be set.
Password attribute
This attribute ensures security by requesting the input of a password before
the screen is displayed.
If an incorrect password is input, the screen will not be displayed.
The password is set as a four-digit numerical value.
Display history attribute
The following three types of data are recorded each time a screen is displayed:
Display time:
Time when the screen was displayed
(month, day, hour, minute)
Screen number: Screen number of the displayed screen
Screen comment: The comment set for the displayed screen
The recorded data can be printed out using the printing function of the NT11.
Menu screen attribute
This attribute makes it possible to switch to another screen by using the
numeric keys.
Assigning the screen numbers of destination screens to numeric keys [1]
through [4] enables switching to these screens by numeric key input.

Contiguous areas (4 words for the PT status control area and 3 words for the
PT status notify area) must be allocated in the PLC memory in advance.
Screen switching, memory table copy and PT status change operations, etc.,
are possible by using the PT status control area and PT status notify area.
Allocating numeral memory table entries/character string memory table entries
Allocating memory table entries to a data area secured in the PLC memory
allows the display to be automatically updated.
4-3-3
NT11 Status Control and Notification to PLC
This section describes the fundamentals of the display elements, NT11 status
control, and notification which are the basics of the NT11 functions.
For the detail method of use of the PT status control area and the PT status
notify area, refer to 5-5 NT11 Status Control (page 129) and 5-6 Notification of
the Operating Status to the PLC (Determining the NT11 Operating Status)
(page 132).
Controlling the Display Elements by Using Allocated Bits and Words
The NT11 will operate as follows in the display element control operation.
[NT11 operation]
1,2,3...
1. The NT11 checks the allocation bits and words of the display elements and
makes an inquiry to the PLC.

Printing procedure
Explained here is the procedure for printing a display history in response to an
instruction from the PLC.
The printing instruction from the PLC takes effect by setting the status of bit 5
(display history printing) of the PT status control area.
To designate printing, bit 5 of the PT status control area is set to “1”. One
report is printed each time bit 5 is set to “1”. To print the report again, the bit
status must be returned to “0” and then set to “1” again.

The Auxiliary Area of the CVM1 and CV-series PLCs is allocated to system
functions, and cannot be used for purposes other than system use.
The range of each memory area differs according to the PLC. Refer to Appendix D Making the Cable on page 153.
Procedure
1. Use the support tool to allocate the PT status control area (PLC to PT) to
the PLC memory.
2. Create a PLC program to write the number of the displayed screen to the
“screen switch setting word” in the PT status control area.
Reference
Use a 4-digit BCD (binary-coded decimal) value to set a screen number.
If a screen has been switched by operating the PT status control area (PLC to
PT), the contents of the “currently displayed screen word” in the PT status
notify area (PT to PLC) also change.
• Screen switching timing
The NT11 screen switches when the contents of the “screen switch setting”
have changed. To re-specify the number of the currently specified screen,
first write the value 0000 to clear the screen before writing the appropriate
screen number.
111
Outline of Host Link/NT Link Operation
Section 5-2
• Use of the screen switching strobe
Create a program to read the number of the currently displayed screen and
to write the number to the “screen switch setting word” at the leading edge
of the “screen switching strobe” of the PT status notify area. This program
enables screen switching by using the Menu screen on the NT11 and eliminates repeated setting of the same screen number. If the screen switching
is not executed on the NT11, the screen switching strobe does not need to
be checked.
For the screen switching strobe, refer to the “notifying the displayed screen to
the PLC” mentioned below.
Example of Display Screen Switching
This example operates the PLC switch (bit) to switch the NT11 display screen.
• Support tool settings
Make the following settings with the support tool:
PT status control area: Word 0100

• Displaying the numeral memory table entry
Numerals can be displayed in three different ways according to the contents of the numeral memory table entry, as mentioned below.
The most significant digit (digit 4 of a single word or digit 8 of a double
word) is processed in different ways.
Decimal display without signs:
If the most significant digit is “F”, it is handled as “0”, and the most significant digit
other than “F” and other digits are handled as stored in the allocated words.
Decimal display with signs:
If the most significant digit is “F”, it is handled as “–” (minus sign), and the most
significant digit other than “F” and other
digits are handled as stored in the allocated words.

If the hexadecimal data (A to F) are stored when the decimal display has
been set, the alphabets are displayed.
If the number of display digits has been set to be smaller than the maximum number of digits of the registration words (4 digits for 1 word; 8 digits
for 2 words), the contents of the allocated words are not displayed and “*”
symbols will be displayed at all digits.
If the most significant digit is “F” when “decimal with signs” has been set,
the numeral is handled as a negative number. The maximum number of
digits of the negative number becomes smaller than that of the positive
number by 1 digit.
Reference
The actual display will vary according to the “zero suppress” setting and decimal fraction setting as well as the contents mentioned above. Refer to the “NTseries Support Tool Operation Manual” ([email protected]).
• Contents of the character-string memory table entry
A character-string is stored in the allocated words beginning with the first
word in half-size characters.
Two half-size characters are stored in one word. One memory table entry
can store up to 10 words (20 characters).

When it is necessary to display changing data such as monitored data of
words in the PLC, use the numeral and character-string memory tables. This
must be used to change the display contents (contents of memory table entry
or words).
1. Use the support tool to allocate the numeral and character-string memory
table entries to the PLC memory.
2. Register the memory table entries for the numerals and character-strings
to be displayed when creating the screen data by using the support tool.
To display a character-string, use “character display” and specify the character-string memory table entry by using the support tool.
To display numerals, use “numeral display” and specify the numeral memory table entry by using the support tool.
3. Create a PLC program to write the contents of numerals and characterstrings to be displayed on the NT11 to the PLC words.
Application Example of the Numeral Memory Table Entries Allocated to the PLC Words
This example gives the procedure to directly display the contents of the words
allocated as the numeral memory table entries in the PLC memory. The NT11
screen display will change as the contents of the PLC word change.
• Support tool settings
Allocate the memory as shown below by using the support tool.
Numeral memory table entry No. 1: DM0000 (allocated words: 2 words)
Numeral memory table entry No. 2: DM0002 (allocated words: 1 word)

Reference
1. Use the support tool to allocate the PT status control area (PLC to PT) to
the PLC memory.
2. Register the memory table entries for the numerals and character-strings
to be displayed when creating the screen data by using the support tool.
To display a character-string, use “character display” and specify the character-string memory table entry by using the support tool.
To display numerals, use “numeral display” and specify the numeral memory table entry by using the support tool.
3. Set the copy source data to the memory table entry when creating the
screen data by using the support tool.
Use “table edit”.
4. Create a PLC program to write the copy type, copy destination memory table entry number, and copy source memory table entry number to the
“copy memory table entry” setting word in the PT status control area.
• Order for writing to the PT status control area (PLC to PT)
First write the “copy destination memory table entry number”, and then,
write the “copy source memory table entry number” to the PT status control
area (PLC to PT).
The NT11 reads the area sometimes when the PLC is writing the settings.
If the “copy source memory table entry number” has been written first and
is changed, an unexpected memory table entry may possibly be changed.
• Allocated words that the NT11 reads
The NT11 reads the allocated words in the PLC for the memory table entries which need to be displayed. If the copy source memory table entry is
allocated to a PLC word, it may sometimes be used at the initialization only.
• Use of the “copy type”
Copy will not be executed when the “copy type” is other than “0” or “1”. The
memory table entry copy is executed only when the contents of the area
are changed. To repeat copying of the same copy source and same copy
destination, write a value other than “0” or “1” for the copy type, and then,
write a correct value again.
• Copying a numeral memory table entry
If the display method or the number of registered words include discrepancies, a numeral memory table entry may not be copied and displayed correctly.

Notification of Numbers to the PLC
This section describes how the numerical data input at an NT11 is ascertained by the PLC.
In order to determine when numerical data has been input at the NT11, the
numeral setting strobe flag in the PT status notify area is used. In order to
determine the upgraded numeral memory table entry number, the “content
upgrade memory table entry” in the PT status notify area is used.
When numerical data is input at the NT11, this is automatically notified to the
PT status notify area (PT ® PLC) allocated in the PLC memory as follows.
Notification of upgrade:
PT status numeral setting strobe flag
turned ON (1)
Upgraded numeral table entry number:Stored in the “content upgrade
memory table entry”
When the PLC reads the “content upgrade memory table entry” at the leading
edge of the numeral setting strobe flag, it determines the numeral memory
table entry number in which the numerical data that was changed at the NT11
is stored.

• Program operation
1. When the numeral setting strobe flag (bit 11211) comes ON (1), the contents of CIO/IR 0111 (the word where the content upgrade memory table
entry is located) are transferred to DM 0105. The number of the numeral
memory table entry that contains the upgraded data is stored in DM 0105
(in this case it is 003 or 004).
If the numeral memory table entry is allocated to a PLC word, the value input to it can be read easily by referring to the allocated word.
In this case, the contents of numeral memory table entry No. 3 are stored
in DM 0005 and the contents of numeral memory table entry No. 4 are
stored in DM 0006.

The NT11 functions that can be controlled from the PLC are listed below:
Whether the screen is displayed or not
Whether display histories are printed or not
Whether daily reports are printed or not
Note
Since the PT status control bits remain unaffected even if the NT11 status
changes in accordance with the screen attribute and memory switch settings,
it can happen that the status indicated by the PT status control bits does not
agree with the actual status of the NT11. For example, the screen may be off
although the screen display setting is “ON”. In situations like this, control the
NT11 by using the PT status control bits.
• Screen display (bit 15)
The screen display bit determines whether the backlight is lit or unlit
(whether the screen is displayed or not). It is used to prolong the service
life of the backlight and prevent the formation of an afterimage. When bit
15 is set to OFF (0), the backlight is switched off.
Once the screen has been switched off, it can be switched back on either
by switching bit 15 ON (setting it to “1”) or by pressing an NT11 key; this
will cause the backlight to come back on.
129
NT11 Status Control
Section 5-5
Reference
1. Instead of switching bit 15 ON, a screen number can be specified to switch
to that screen, in which case the screen will be displayed. For details on
screen switching, refer to 5-2-2 Switching the Screen Display (page 110).
2. By setting an NT11 memory switch, it is possible to make the backlight go
off automatically after no operations have been performed for a set length
of time.
• Display history print (bit 5)
”Display history printing” designates printing of the display history data recorded in the NT11 at a printer. When bit 5 is set ON (set to “1”), all the
recorded display history data is printed out once. To print it out a second
time, bit 5 must be switched OFF (set to “0”) and then switched back ON
(to “1”).
Reference
For details on the data recorded in the display history and the printing format,
refer to 4-10 Daily Report/Display History Printing Function (page 102).
• Daily report print (bit 4)
“Daily report print” designates printing of the contents of PLC words and
set characters in accordance with a format set using the support tool.
When bit 4 is switched ON (set to “1”), the contents of the specified words
are read from the PLC and output to the printer once in the specified format.
To output the data to the printer again, bit 4 must be switched OFF (set to
“0”) and then switched back ON (to “1”).
Reference
5-5-2
Settings such as the printing format and word settings are made by using the
support tool. For details on the support tool setting procedures relating to the
daily report printing function, refer to 4-10 Daily Report/Display History Printing Function (page 102).
How to Control NT11 Functions

The range of each memory area differs according to the PLC type. Appendix H Special Characters (page 163) for more details.
Procedure
1. Use the support tool to allocate the PT status control area (PLC ® PT) to
the PLC memory.
2. Create a PLC program to write control data to the “PT status control bits”
of the PT status control area.
• Control timing of PT status control bits
The PT status control area (PLC ® PT) is not read when the NT11 starts
up. It is only read, and control is only executed, when the contents of the
PT status control area are changed after the NT11 has been started up.
Since control of the NT11 statuses is executed after the bits corresponding
to the PT status control bits have changed, to execute control again the
corresponding bits must be specified again.
Example use of the PT status control bits
The example below shows how the PT status control bits are used to execute
daily report printing.
• Setting at the support tool
Perform the following setting with the support tool.
PT status control area allocated word: CIO/IR 0118
• PLC program
Create the following PLC ladder program:

• Program operation
1. When CIO/IR 00110 comes ON, the daily report printing bit (bit 4) of the
PT status control area is set to “1”. The status of bits other than bit 4 remains unchanged.
When bit 4 is set to “1”, the daily report is printed.

• PT operation status (bit 15)
When the NT11 is in the RUN mode this bit is ON (“1”). In other modes,
and when the system menu is displayed, it is OFF (“0”). When it is OFF
(“0”), the allocated bits and words cannot be read or written to.
• Screen switching strobe (bit 12)
When the screen displayed by the NT11 is switched by an instruction from
the PLC, or by the standalone function, the screen switching strobe comes
ON (“1”). On notification to the PLC, it goes OFF (“0”).
• Numeral setting strobe flag (bit 11)
When a numerical value has been set in a numeral memory table entry using the numeral setting function of the NT11, the numeral setting strobe
flag is ON (“1”). On notification to the PLC, it goes OFF (“0”).
132
Notification of the Operating Status to the PLC (Determining the NT11 Operating Status)
Section 5-6
For details on how the numeral setting strobe flag is used, refer to “Notification of Numbers to the PLC”.
• Password input error flag (bit 9)
If a value that does not match the password registered in NT11 password
setting is input in three successive attempts, the password input error flag
comes ON (“1”). On notification to the PLC, it goes OFF (“0”).
For details on how the password input error flag is used, refer to 4-8 Password Screen Display Function (page 100).
5-6-2
Reading the NT11 Operating Statuses
This section explains the actual procedures used to determine the NT11 statuses and operating statuses.
Note
To ensure system safety, be sure to make a program which periodically reads
the PT operating status bit in order to confirm that the PT is operating normally.
In order to ascertain the NT11 operating statuses, the PT status notification
bits are used.
The NT11 automatically notifies information such as operating statuses to the
PT status notification bits in the PT status notify area (PT –> PLC) allocated in
the PLC memory, as follows:
Notification of operating mode:
“PT operation status”
Notification of screen switching:
“Screen switching strobe”
Notification of numerical value updates: “Numeral setting strobe flag”
Notification of password input mistakes: “Password input error flag”
• Restrictions on allocating words
The PT status notify area (PT ® PLC) can be allocated to the PLC memory
areas listed in the following table.
Words can be allocated for the PT status notify area (PT ® host) in the following host (PLC) areas.

Inspection and Cleaning
Clean and inspect the NT11 regularly to ensure that it is always used in its
optimum condition.
Cleaning Method
If the display is dirty the screen is difficult to see. Clean the screen from time
to time as follows.
• In daily cleaning, wipe the display with a soft dry cloth. If the soiling is particularly heavy, attempting to remove it by wiping with a dry cloth may
damage the front sheet of the Unit. In this case, wipe with a damp cloth.
• If the soiling cannot be removed with a dry cloth, wet the cloth with diluted
neutral detergent (2%), wring it out well and wipe the display with it.
• If rubber or vinyl products, tape, etc., are left stuck to the display for long
periods they will cause staining. If such items are stuck to the display,
remove them during cleaning.
Note Never use volatile solvents such as benzene or thinners, or chemical dusters.
Otherwise the product may malfunction.
Inspection Method
In normal environments, inspect the NT11 at intervals of between 6 months
and a year. In environments that are extremely hot and humid, or very dusty
environments, shorten the inspection interval.
Items Required for the Inspection
Prepare the following items before starting the inspection.
• Screwdrivers (Phillips, flat head)
• Tester (or digital voltmeter)
• Industrial alcohol
• 100% cotton cloth
• Hygrometer (required in some cases)
• Thermometer (required in some cases)
• Synchroscope (required in some cases)
• Pen-writing oscilloscope (required in some cases)

NT11 Internal Processing
When host link/NT link is used, the following processing is executed inside the NT11. Processing is divided into
two types: periodic processing and event processing.
Periodic Processing
When the NT11 is in the RUN mode it executes the following internal processing cyclically. The contents of all
the allocated bits and words used for screen display are read from the PLC at one time, allowing high-speed
processing.
[NT11 processing]
[Details of processing]
NT11 power ON
Hardware check, communication status check, etc.,
executed
Initial processing
Operation start
(PT→PLC)
When the values registered in the NT11S are used as
the initial values in the memory tables, these values are
written into the allocated words of the PLC.
The allocated bits and words for the display
elements that have to be read from the PLC
are registered in the PLC.
(PT→PLC)
Registration of the read allocated bits and words in the
PLC
Reading of allocated bits and words
(PT←PLC)
The contents of the allocated bits and words registered
in the PLC are all read at one time.
Initial values written to the memory tables
Screen switching
Note
(1) Only the data of the PLC Status Control Area and data for currently displayed screens is read from
the PLC.
Even if the contents of the PLC words allocated as memory table entry entries are changed, the
data are not upgraded at the NT11 unless these memory table entries are used for screen displays.
(2) The maximum number of bits/words that can be read is 120 words per screen.
If the number that can be read is exceeded, the data are not upgraded.
157
NT11 Internal Processing
Appendix F
Event Processing
When the status of the NT11 changes during operation, the processing for writing the changed data to the relevant area of the PLC memory is executed.
This kind of processing is only executed when statuses change. When changes occur simultaneously, the process is executed in accordance with the order of priority.
[NT11 processing]
Order of priority
High Writing to the PT status notify area

when the value in a numeral memory table has
changed.
Note Data is only written to PLC bits and numeral/character string memory table entries for elements in
screens currently being displayed. If the contents of numeral/character string memory table entries that
are not being displayed change, the changed contents are not written to the PLC.
