8.2 Upload Protection
8.2.1 Upload Protection
Overview of program upload protection function
- This function is to prohibit reading programs and system registers by setting to disable program
uploading.
- If the upload protection is set, note that the ladder programs and system registers will be disabled to be
uploaded after that. Transferring programs to the FP memory loader will be also unperformable.
- The setting can be cancelled using the programming tool, however, all ladder programs, system
registers and password information will be deleted when the setting is cancelled.
- Editing the files that are controlled with a PC can be carried out online using the programming tool.
However, the programs will be broken if the programs are not absolutely matched. When using this
function, store ladder programs as files without fail.
Interaction with the password protect function
- The password setting can be specified simultaneously for the PLC in which this function is set.
- This function can be also set in a password-protected PLC.
Note:
When performing "Release the upload-protection by compulsion"
- All programs and security information will be deleted when the upload protection setting is cancelled.
We cannot restore the deleted programs even if you ask us. We cannot read the data of the PLC in
which the program upload protection has been set. Keeping your programs is your responsibility.
