Omron CP1E-N60DR-D Compact PLC CPU

1. If CX-Programmer Ver. 3.2 or a lower version is used to read a task with

task read protection applied, an error will occur and the task will not be

read. Likewise, if a Programming Console or the PT Ladder Monitor func

tion is used to read a password protected task, an error will occur and the

task will not be read.

2. The entire program can be transferred to another CPU Unit even if individ

ual tasks in the program are read-protected. It is also possible to connect

online and create a program file (.OBJ file) with file memory operations. In

both cases, the task read protection remains effective for the password

protected tasks.

3. When the CX-Programmer is used to compare a user program in the com

puter’s memory with a user program in the CPU Unit, password-protected

tasks will be compared too.

Restrictions to Function

Block Use

Function block definitions can be read even if the entire program or individual

tasks in a program containing function blocks (CPU Unit Ver. 3.0 or later only)

are read-protected.

Enabling/Disabling Creating File Memory Program Files

Previous CPU Units (Pre

Ver. 2.0 CPU Units)

CPU Unit Ver. 2.0 or Later

and CX-Programmer

Ver. 4.0 or Higher

With the pre-Ver. 2.0 CS/CJ-series CPU Units, it was possible use file mem

ory operations to transfer a program file (.OBJ file) to a Memory Card even if

the program was protected with UM read protection. (Consequently, illegal

copies could be made.)

Overview

When the entire program or individual tasks in a CPU Unit Ver. 2.0 or later are

read-protected from the CX-Programmer, an option can be set to enable or

disable the creation/backup of .OBJ program files. It will not be possible to

create program files (.OBJ files) with file memory operations if the creation/

backup of program files is prohibited with this setting. (This setting prohibits

both online transfers to a Memory Card/EM file memory as well as offline stor

age of PLC data that was uploaded to the CX-Programmer.)

Disabling the creation of file memory program files can help prevent illegal

copying of the user program

Operating Procedure

1.2.3…

1. When registering a password in the UM read protection password Box or

Task read protection Box, select the Prohibit from saving into a protected

memory card Option.

Properties

2. Either select PLC – Transfer – To PLC to transfer the program or select

PLC – Protection – Set Password and click the OK button.

Usage

This option can be used to prevent the program from being transferred out of

the PLC using the password.

Note

1. The simple backup operation can still be performed when the creation of

program files is prohibited, but the backup program file (BACKUP.OBJ) will

not be created.

2. The program can be copied when program read protection is not enabled.

3. The setting to enable/disable creating file memory program files will not

take effect unless the program is transferred to the CPU Unit. Always trans

fer the program after changing this setting.

Enabling/Disabling Write Protection for Individual Tasks Using Passwords

Previous CPU Units (Pre

Ver. 2.0 CPU Units)

With the pre-Ver. 2.0 CS/CJ-series CPU Units, the CPU Unit’s user program

memory (UM) can be write-protected by turning ON pin 1 of the CPU Unit’s

DIP switch. In this case, it is possible to overwrite the user program memory

by turning OFF pin 1.

CPU Unit Ver. 2.0 or Later

and CX-Programmer

Ver. 4.0 or Higher

With the CPU Unit Ver. 2.0 and later CPU Units, the CPU Unit’s UM area can

be write protected by turning ON pin 1 of the CPU Unit’s DIP switch. The pro

gram (or selected tasks) can also be write-protected if the write protection

option is selected from the CX-Programmer when a password is being regis

tered for the entire program or those selected tasks. The write protection set

ting can prevent unauthorized or accidental overwriting of the program.​
