Password protection can be set in the Loop Controller when using LCB01,
LCB03, LCB05, or LCB05D. Setting a password enables uploading operations
to be restricted. No restrictions are placed on downloading.

online.
Note Once a password is set, it must be input under Program Protection – Input

1. Select the LCU/LCB element (e.g., 00-LCB05), and then select Setting –
Program Protection – Edit LCB Password. The following dialog box will

Use the following procedure to change the password set for the Loop Controller

tion. Backing up to a Memory Card will thus be disabled, although restoring data
will be possible. If the simple backup operation to a Memory Card is performed
for a Loop Controller for which a password has been set, an empty backup file
will be created in the Memory Card.
