Hi Nasir,

In order to help give accurate info which PLC and terminal are you using?

But yes... Check out the CX-Programmer Help topic "Protection" and see CX-Programmer menu PLC->Protection. Both Program and/or any Function Blocks can be password protected to prevent uploading (without the password).

There are also other techniques too I think for older PLCs that I've seen documented here: How Do I Protect A Password - CX-Programmer? (just for your information)

Bertie

There is no copy protection for NT30 or NT630.

BTW: These have been obsolete since 2002.
