14.7.3 Cautions in registering keyword
1. Cautions in registering keyword
The keyword limits access to the program prepared by the user from peripheral devices.
Keep the keyword carefully.
If you forget the keyword, you cannot operate the PLC online from the programming tool depending on the
type of the programming tool and the registered keyword.
2. Caution on using a peripheral device which does not support the second keyword and
customer keyword
Sequence programs in which the second keyword and customer keyword are registered cannot be all-cleared
using the programming tool (GX Developer whose version is earlier than Ver. 8.72A).
3. Non-resettable protect function
When the non-resettable protect function is set, the protect function cannot be reset.
