Downloading and Uploading Individual Tasks

Previous CPU Units (Pre-Ver. 2.0 CPU Units)

With the Pre-Ver. 2.0 CPU Units, individual program tasks could not be down

loaded from the CX-Programmer. It was only possible to download the entire

user program.

For example, if several programmers were developing the program, the

project manager had to unify each program after debugging and then down

load the entire user program. Furthermore, the entire user program had to be

downloaded even if just a few changes were made.

Note It was possible to upload individual program tasks with CS/CJ-series PLCs

When several programmers are developing a program, it isn't necessary for a

project manager to unify the data because just the debugged tasks can be

downloaded/uploaded. Also, transferring individual tasks can help avoid mis

takes

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 to read-protect

the entire PLC with a password (referred to as “UM read protection” below),

but it was not possible to protect individual tasks.

UM read protection prevented anyone from displaying, editing, or uploading

the entire user program from CX-Programmer without inputting the correct

password.

Overview

With the CPU Unit Ver. 2.0 or later CPU Units, it is possible to read-protect

individual program tasks (referred to as “task read protection” below) or the

entire PLC. same password controls access to all of the read-protected tasks.

Task read protection prevents anyone from displaying, editing, or uploading

the read-protected set of tasks from CX-Programmer without inputting the cor

rect password. In this case, the entire program can be uploaded, but the read

protected tasks cannot be displayed or edited without inputting the correct

password. Tasks that are not read-protected can be displayed, edited, or mod

ified with online editing.
