OMRON CJ1G-CPU43H CPU

OMRON  CJ1G-CPU43H  CPU

A “unit version” has been introduced to manage CPU Units in the CS/CJ

Series according to differences in functionality accompanying Unit upgrades.

This applies to the CS1-H, CJ1-H, CJ1M, and CS1D CPU Units.

The unit version is given to the right of the lot number on the nameplate of the

products for which unit versions are being managed, as shown below.

Unit version

Example for Unit version 3.0

• CS1-H, CJ1-H, and CJ1M CPU Units manufactured on or before Novem

ber 4. 2003 do not have a unit version given on the CPU Unit (i.e., the

location for the unit version shown above is blank).

• The unit version of the CJ1-H-R CPU Units begins at version 4.0.

• The unit version of the CS1-H, CJ1-H, and CJ1M CPU Units, as well as

the CS1D CPU Units for Single-CPU Systems, begins at version 2.0.

• The unit version of the CS1D CPU Units for Duplex-CPU Systems, begins

at version 1.1.

• CPU Units for which a unit version is not given are called Pre-Ver. @.@

CPU Units, such as Pre-Ver. 2.0 CPU Units and Pre-Ver. 1.1 CPU Units.

Confirming Unit Versions

with Support Software

CX-Programmer version 4.0 can be used to confirm the unit version using one

of the following two methods.

• Using the PLC Information

• Using the Unit Manufacturing Information (This method can be used for

Special I/O Units and CPU Bus Units as well.)

Note CX-Programmer version 3.3 or lower cannot be used to confirm unit versions.

PLC Information

• If you know the device type and CPU type, select them in the Change

PLC Dialog Box, go online, and select PLC - Edit - Information from the

menus.

• If you don't know the device type and CPU type, but are connected

directly to the CPU Unit on a serial line, select PLC - Auto Online to go

online, and then select PLC - Edit - Information from the menus.

In either case, the following PLC Information Dialog Box will be displayed.

User programs that contain functions supported only by CPU Units with unit

version 4.0 or later cannot be used on CS/CJ-series CPU Units with unit ver

sion 3.0 or earlier. An error message will be displayed if an attempt is made to

download programs containing unit version 4.0 functions to a CPU Unit with a

unit version of 3.0 or earlier, and the download will not be possible.

If an object program file (.OBJ) using these functions is transferred to a CPU

Unit with a unit version of 3.0 or earlier, a program error will occur when oper

ation is started or when the unit version 4.0 function is executed, and CPU

Unit operation will stop.
