Direct Connection Function
Section 1-5
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
Features of the 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.
• 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.

Connecting to a CVM1/CV-series Host Link Unit
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).

2-5 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 (RS-
422A 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 Commu-
2-5-1 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.

Precautions to be Observed During the Screen Data Transmission
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 NT11. If an error message is displayed in the System Menu and the Transmit Mode cannot be selected, the screen data memory needs to be initialized.
• The power to the NT11 is interrupted or the NT11 is reset.
• The power to the computer on which the support tool is running is interrupted or the computer is reset.
• The cable connecting the NT11 to the computer on which the support tool is running is disconnected or has a broken wire.
• Screen data transfer is terminated by pressing any two of the function keys on the panel of the NT11.
• The ESC key on the support tool is pressed to end the transmission.
When the power to the NT11 is turned ON or reset, the screen data is checked. However, if 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-SW2-2 to ON to initialize the memory.
For the memory initialization by using the DIP switch, refer to 3-4-2 Initializa-
tion by Using the DIP Switch (Forced Initialization) (page 65).
3-7 Setting the Conditions of Communications with the PLC by Using the Memory Switches
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.
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 subsequent pages for the details of each setting and function.

4-2-2 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
Display history attribute
Menu screen 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.
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.
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.

Procedure
*1 LR 00000 to LR 00199 are converted to CIO 01000 to CIO 01199.
*2 The EM Area is supported only by the C200HX/HG/HE(-Z)E PLCs.
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 Appen-
dix D Making the Cable on page 153.
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” (V061-E1-

Procedure
Reference
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.

5-4-1 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.

Create the following PLC ladder program.
11211
@MOV(21)
111
DM0105
(1)
Notification word for content upgrade memory table entry
Word that stores the numeral memory table entry number
Numeral setting strobe flag
• 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.

Note: When "screen display = yes" is set, the backlight is lit; when "screen display = no" is set, the backlight is off.
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
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

Procedure
*1 LR 00000 to LR 00199 are converted to CIO 01000 to CIO 01199.
*2 The EM Area is supported only by the C200HX/HG/HE(-Z)E PLCs.
The range of each memory area differs according to the PLC type. Appen-
dix H Special Characters (page 163) for more details.
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:
00110

• 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.

2.
When CIO/IR 00111 comes ON, the daily report printing bit (bit 4) of the
PT status control area is set to “0”. The status of bits other than bit 4 remains unchanged.
5-6 Notification of the Operating Status to the PLC
(Determining the NT11 Operating Status)
The status (operating statuses, etc.) of the NT11 can be determined from the
PLC by reading the “PT status” word in the PT status notify area allocated in the PLC memory.

• 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 Pass-
word 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:
Notification of screen switching:
“PT operation status”
“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

Clean and inspect the NT11 regularly to ensure that it is always used in its optimum condition.
Cleaning Method
Inspection Method
Point Inspected
Power supply voltage
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.
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)
Points inspected
Inspect the following points to determine if there is any divergence from the stated criteria. If there is, either improve the surrounding environment so that the values fall within the stated range, or adjust the NT11.

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]
NT11 power ON
[Details of processing]
Initial processing
Operation start
Hardware check, communication status check, etc., executed
Initial values written to the memory tables
(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.
Screen switching
The allocated bits and words for the display elements that have to be read from the PLC are registered in the PLC.
Reading of allocated bits and words
(PT
→PLC)
Registration of the read allocated bits and words in the
PLC
(PT
←PLC)
The contents of the allocated bits and words registered in the PLC are all read at one time.
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]
High
Writing to the PT status notify area (PT
→PLC)
[Details of processing]
Writing to the PT status notify area in order to inform the PLC of changes in the PT operating status.

Terms and Conditions of Sale
1.
Offer; Acceptance. These terms and conditions (these "Terms") are deemed part of all quotes, agreements, purchase orders, acknowledgments, price lists, catalogs, manuals, brochures and other documents, whether electronic or in writing, relating to the sale of products or services (collectively, the "Products") by Omron Electronics LLC and its subsidiary companies (“Omron”). Omron objects to any terms or conditions proposed in Buyer’s purchase order or other documents which are inconsistent with, or in addition to, these Terms.
2.
Prices; Payment Terms. All prices stated are current, subject to change without notice by Omron. Omron reserves the right to increase or decrease prices on any unshipped portions of outstanding orders. Payments for Products are due net 30 days unless otherwise stated in the invoice.
3.
Discounts. Cash discounts, if any, will apply only on the net amount of invoices sent to Buyer after deducting transportation charges, taxes and duties, and will be allowed only if (i) the invoice is paid according to Omron’s payment terms and (ii) Buyer has no past due amounts.
4.
Interest. Omron, at its option, may charge Buyer 1-1/2% interest per month or the maximum legal rate, whichever is less, on any balance not paid within the stated terms.
5.
Orders. Omron will accept no order less than $200 net billing.
6.
Governmental Approvals. Buyer shall be responsible for, and shall bear all costs involved in, obtaining any government approvals required for the importation or sale of the Products.
7.
Taxes. All taxes, duties and other governmental charges (other than general real property and income taxes), including any interest or penalties thereon, imposed directly or indirectly on Omron or required to be collected directly or indirectly by Omron for the manufacture, production, sale, delivery, importation, consumption or use of the Products sold hereunder (including customs duties and sales, excise, use, turnover and license taxes) shall be charged to and remitted by Buyer to Omron.
8.
Financial. If the financial position of Buyer at any time becomes unsatisfactory to Omron, Omron reserves the right to stop shipments or require satisfactory security or payment in advance. If Buyer fails to make payment or otherwise comply with these Terms or any related agreement, Omron may (without liability and in addition to other remedies) cancel any unshipped portion of Products sold hereunder and stop any Products in transit until Buyer pays all amounts, including amounts payable hereunder, whether or not then due, which are owing to it by Buyer. Buyer shall in any event remain liable for all unpaid accounts.
9.
Cancellation; Etc. Orders are not subject to rescheduling or cancellation unless Buyer indemnifies Omron against all related costs or expenses.
10. Force Majeure. Omron shall not be liable for any delay or failure in delivery resulting from causes beyond its control, including earthquakes, fires, floods, strikes or other labor disputes, shortage of labor or materials, accidents to machinery, acts of sabotage, riots, delay in or lack of transportation or the requirements of any government authority.
11. Shipping; Delivery. Unless otherwise expressly agreed in writing by Omron: a. Shipments shall be by a carrier selected by Omron; Omron will not drop ship except in “break down” situations.
b. Such carrier shall act as the agent of Buyer and delivery to such carrier shall constitute delivery to Buyer; c. All sales and shipments of Products shall be FOB shipping point (unless otherwise stated in writing by Omron), at which point title and risk of loss shall pass from Omron to Buyer; provided that Omron shall retain a security interest in the Products until the full purchase price is paid; d. Delivery and shipping dates are estimates only; and e. Omron will package Products as it deems proper for protection against normal handling and extra charges apply to special conditions.
12. Claims. Any claim by Buyer against Omron for shortage or damage to the
Products occurring before delivery to the carrier must be presented in writing to Omron within 30 days of receipt of shipment and include the original transportation bill signed by the carrier noting that the carrier received the Products from Omron in the condition claimed.
13. Warranties. (a) Exclusive Warranty. Omron’s exclusive warranty is that the
Products will be free from defects in materials and workmanship for a period of twelve months from the date of sale by Omron (or such other period expressed in writing by Omron). Omron disclaims all other warranties, express or implied.
(b) Limitations. OMRON MAKES NO WARRANTY OR REPRESENTATION,
EXPRESS OR IMPLIED, ABOUT NON-INFRINGEMENT, MERCHANTABIL-
ITY OR FITNESS FOR A PARTICULAR PURPOSE OF THE PRODUCTS.
BUYER ACKNOWLEDGES THAT IT ALONE HAS DETERMINED THAT THE
PRODUCTS WILL SUITABLY MEET THE REQUIREMENTS OF THEIR
INTENDED USE. Omron further disclaims all warranties and responsibility of any type for claims or expenses based on infringement by the Products or otherwise of any intellectual property right. (c) Buyer Remedy. Omron’s sole obligation hereunder shall be, at Omron’s election, to (i) replace (in the form originally shipped with Buyer responsible for labor charges for removal or replacement thereof) the non-complying Product, (ii) repair the non-complying
Product, or (iii) repay or credit Buyer an amount equal to the purchase price of the non-complying Product; provided that in no event shall Omron be responsible for warranty, repair, indemnity or any other claims or expenses regarding the Products unless Omron’s analysis confirms that the Products were properly handled, stored, installed and maintained and not subject to contamination, abuse, misuse or inappropriate modification. Return of any Products by
Buyer must be approved in writing by Omron before shipment. Omron Companies shall not be liable for the suitability or unsuitability or the results from the use of Products in combination with any electrical or electronic components, circuits, system assemblies or any other materials or substances or environments. Any advice, recommendations or information given orally or in writing, are not to be construed as an amendment or addition to the above warranty.
See http://oeweb.omron.com or contact your Omron representative for published information.
14. Limitation on Liability; Etc. OMRON COMPANIES SHALL NOT BE LIABLE
FOR SPECIAL, INDIRECT, INCIDENTAL, OR CONSEQUENTIAL DAMAGES,
LOSS OF PROFITS OR PRODUCTION OR COMMERCIAL LOSS IN ANY
WAY CONNECTED WITH THE PRODUCTS, WHETHER SUCH CLAIM IS
BASED IN CONTRACT, WARRANTY, NEGLIGENCE OR STRICT LIABILITY.
Further, in no event shall liability of Omron Companies exceed the individual price of the Product on which liability is asserted.
15. Indemnities. Buyer shall indemnify and hold harmless Omron Companies and their employees from and against all liabilities, losses, claims, costs and expenses (including attorney's fees and expenses) related to any claim, investigation, litigation or proceeding (whether or not Omron is a party) which arises or is alleged to arise from Buyer's acts or omissions under these Terms or in any way with respect to the Products. Without limiting the foregoing, Buyer (at its own expense) shall indemnify and hold harmless Omron and defend or settle any action brought against such Companies to the extent based on a claim that any Product made to Buyer specifications infringed intellectual property rights of another party.
16. Property; Confidentiality. Any intellectual property in the Products is the exclusive property of Omron Companies and Buyer shall not attempt to duplicate it in any way without the written permission of Omron. Notwithstanding any charges to Buyer for engineering or tooling, all engineering and tooling shall remain the exclusive property of Omron. All information and materials supplied by Omron to Buyer relating to the Products are confidential and proprietary, and Buyer shall limit distribution thereof to its trusted employees and strictly prevent disclosure to any third party.
17. Export Controls. Buyer shall comply with all applicable laws, regulations and licenses regarding (i) export of products or information; (iii) sale of products to
“forbidden” or other proscribed persons; and (ii) disclosure to non-citizens of regulated technology or information.
18. Miscellaneous. (a) Waiver. No failure or delay by Omron in exercising any right and no course of dealing between Buyer and Omron shall operate as a waiver of rights by Omron. (b) Assignment. Buyer may not assign its rights hereunder without Omron's written consent. (c) Law. These Terms are governed by the law of the jurisdiction of the home office of the Omron company from which
Buyer is purchasing the Products (without regard to conflict of law principles). (d) Amendment. These Terms constitute the entire agreement between
Buyer and Omron relating to the Products, and no provision may be changed or waived unless in writing signed by the parties. (e) Severability. If any provision hereof is rendered ineffective or invalid, such provision shall not invalidate any other provision. (f) Setoff. Buyer shall have no right to set off any amounts against the amount owing in respect of this invoice. (g) Definitions. As used herein, “including” means “including without limitation”; and “Omron Companies” (or similar words) mean Omron Corporation and any direct or indirect subsidiary or affiliate thereof.
Certain Precautions on Specifications and Use
1.
Suitability of Use. Omron Companies shall not be responsible for conformity with any standards, codes or regulations which apply to the combination of the
Product in the Buyer’s application or use of the Product. At Buyer’s request,
Omron will provide applicable third party certification documents identifying ratings and limitations of use which apply to the Product. This information by itself is not sufficient for a complete determination of the suitability of the Product in combination with the end product, machine, system, or other application or use. Buyer shall be solely responsible for determining appropriateness of the particular Product with respect to Buyer’s application, product or system.
Buyer shall take application responsibility in all cases but the following is a non-exhaustive list of applications for which particular attention must be given:
(i) Outdoor use, uses involving potential chemical contamination or electrical interference, or conditions or uses not described in this document.
(ii) Use in consumer products or any use in significant quantities.
(iii) Energy control systems, combustion systems, railroad systems, aviation systems, medical equipment, amusement machines, vehicles, safety equipment, and installations subject to separate industry or government regulations.
(iv) Systems, machines and equipment that could present a risk to life or property. Please know and observe all prohibitions of use applicable to this Product.
NEVER USE THE PRODUCT FOR AN APPLICATION INVOLVING SERIOUS
RISK TO LIFE OR PROPERTY OR IN LARGE QUANTITIES WITHOUT
ENSURING THAT THE SYSTEM AS A WHOLE HAS BEEN DESIGNED TO
ADDRESS THE RISKS, AND THAT THE OMRON’S PRODUCT IS PROP-
ERLY RATED AND INSTALLED FOR THE INTENDED USE WITHIN THE
OVERALL EQUIPMENT OR SYSTEM.
2.
Programmable Products. Omron Companies shall not be responsible for the user’s programming of a programmable Product, or any consequence thereof.
3.
Performance Data. Data presented in Omron Company websites, catalogs and other materials is provided as a guide for the user in determining suitability and does not constitute a warranty. It may represent the result of Omron’s test conditions, and the user must correlate it to actual application requirements. Actual performance is subject to the Omron’s Warranty and Limitations of Liability.
4.
Change in Specifications. Product specifications and accessories may be changed at any time based on improvements and other reasons. It is our practice to change part numbers when published ratings or features are changed, or when significant construction changes are made. However, some specifications of the Product may be changed without any notice. When in doubt, special part numbers may be assigned to fix or establish key specifications for your application. Please consult with your Omron’s representative at any time to confirm actual specifications of purchased Product.
5.
Errors and Omissions. Information presented by Omron Companies has been checked and is believed to be accurate; however, no responsibility is assumed for clerical, typographical or proofreading errors or omissions.
