4. I/O Area Allocation

This section explains the difference of I/O area allocation in CQM1H, CJ1M/CJ1G Series, and CJ2M series.

♦Unit Area Allocation for CQM1H

The I/O words are allocated to I/O Units and Dedicated I/O Units in the order of the unit mounting position

from the left to right.

The input relays uses the area starting with IR000 (16 inputs on the CPU Unit always use IR000; other Input

Units uses area starting with IR001). The output relays uses area starting with IR100.

Unit Input relay Output relay

16 inputs built into CPU Unit Always allocated to IR 000. ­Input Units or Dedicated I/O
Units which uses input relay
area

Allocated to the area starting
with IR001. Allocation in the
order of unit mounting position.

-

Output Units or Dedicated I/O
Units which uses output relay
area

- Allocated to the area starting
with IR100. Allocation in the
order of unit mounting position.

♦Unit Area Allocation for CJ1M/CJ1G

There are three unit types. The unit area allocation method is different in each group.

(The unit area allocation is the same as that of CJ2M, though the number of units that can be mounted to

the CPU Unit is different.)

Unit Allocation

Basic I/O Units 0000 to 0079CH

Allocated in the unit of 16
inputs/outputs based on the
actually connected unit
position.

Special I/O Units 2000 to 2959CH

Uses 10 words for each unit.
Allocated according to the Unit
No.

CPU Bus Units 1500 to 1899CH

Uses 25 words for each unit.
Allocated according to the Unit
No.

12

♦Unit Area Allocation for CJ2M

There are three unit types. The unit area allocation method is different in each group.

Unit Allocation Notes

Basic I/O Unit 0000 to 0159CH

Allocated in the unit of 16
inputs/outputs based on the
actually connected unit
position

Same allocation as the
CQM1H can be made if you
set the starting address for the
units. (Note1)

Special I/O Unit 2000 to 2959CH

Uses 10 words for each unit.
Allocated according to the Unit
No.

-

CPU Bus Unit 1500 to 1899CH

Uses 25 words for each unit.
Allocated according to the Unit
No

-

When I/O Area is used in the ladder program, change the CIO area and bit address using the “Change All” or

“Replace” functions of CX-Programmer.

Note1: Unit area allocation same as CQM1H can be configured for CJ2M system, by setting the start

address for each unit using CX-Programmer V9.1 or later (For some systems, same allocation can not be

made). It will reduce CIO area used for Basic I/O Units which must be changed, thus reducing work hour for

modifying ladder program.

The model conversion instructions (below five instructions) which were added for CJ1M CPU Unit Ver. 3.0 or later

can be used with CJ2M CPU Units in the same way as CQM1H series CPU Units.

Those instructions are automatically converterd by executing change model (from CQM1H to CJ2M) on the

CX-Programmer Ver.5 or later (CX-Programmer Ver.5 or later supports functions of CJ1M CPU Unit Ver. 3.0).

Be sure to check the operation, since operation specifications including instruction execution time might differ.

6. Example of converting ladder program by CX-Programmer

This section explains the method of converting the ladder program using CX-Programmer V9.1. Here, convert the

ladder program of CQM1H-CPU61 for CJ2M-CPU** as an example. (This secrion describes the procedure from

loading the ladder program created by CX-Programmer or Sysmac Support Soft (SSS) to converting the program

for CJ2M.)

After converting the ladder program, it is necessary to modify the unit area allocation, operand data, and condition

flag settings, separately. Be sure to confirm the system safety before starting operation.

♦Reading the ladder program of CQM1H

・SSS data

On the CX-Programmer, select File – Open. Set the file type to

“SSS Ladder Program (*.SP1)” and

open the SSS ladder program file for CQM1H. On the below dialog, Click the “Open”.

Then, dialog box to enter the model of CQM1 CPU Unit will be displayed. Enter the model of the CPU

Unit. (For CQM1H, select corresponding CQM1 model.)

・CX-Programmer data

Click the "File" - "Open" and set the file type to CX-Programmer Project Files (*.cxp)". Then, open the

ladder program file of CQM1H created on the CX-Programmer.

37

♦Changing model from CQM1H to CJ2M.

As shown on the below figure, select NewPLC1[CQM1H] and right-click or double click it to change the

PLC model. Please set the CPU model to the Device Type.

The error report might be displayed if there are instructions which cannot be converted.

Please correct and modify the program using support software function or manually, and execute program

check. If errors are detected by the program check, please correct them referring to the error report.

Right-click and

select

“Change” or

double-click.

♦Checking program

Check whether there is problem in the ladder program which was converted from the CQM1H series for

CJ2M series.

Program check

There are 2 types of program check; automatic check on the CX-Programmer and check conducted by

users. CX-Programmer checks the program when “Change model” is executed and the ledder program is

converted.

• Automatic program check on the CX-Programmer

Timing of program check Description
When PLC model is changed. Program check for each PLC model

Check for all instructions and all operands.

You can see the check result on the "Compile (Program check)" tab of the Output Window.

The left bus-bar on the ladder section window turns red if there is an error in the rung.

• Program check conducted by users

This section describes the procedure of program check, an example of checking result, and

explanation of error levels.

<Program check for one program (task)>

1. Select the ladder section window or nimonic window to check.

2. Select “Program” – “Compile (Program check)”.

The results of program check will be displayed on the Output Window. Refer to “Results of program

check” on the next page for details.

38

• Checking the entire program

Select “PLC” – “Compile All PLC Programs”.

You can see the program check results on the Output Window.

Refer to “Results of program check” for details.

<Results of program check>

You can see the check result on the "Compile (Program check)" tab of the Output Window.

There are three error levels; errors are divided and shown for each level.

When there is no error.

When there are errors.

Double-click an error on the Output Window to jump to the correposnding cell.

Numeric data in ( , ) shows the position of a cell with an error.

If you right-click on the Output Window, below menus are shown.

Menu Functions
[Clear] Clears the content of Output Window.

Same as selecting “Edit” – “Clear Compile Window”.

[Next Reference] Jump to the error cell next to the error now selected.

Same as selecting “Edit” – “Next Reference”.

[Allow Docking] Output Window is shown on the main window of the

CX-Programmer. If unckeck the check box, Output
Window will be shown on the separate window.

[Hide] Close the output window.

Same as selecting “View” – “Window” – “Output”.

[Float In Main Window] Output window will be changed to other window (ex.

Ladder section window).

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

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 B uyer 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 oth-

erwise 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 inter-

est 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 nor-

mal 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.

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

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://www.omron247.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 ST RICT 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 PROP­ERLY RATED AND INSTA LLED 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.
