Password
You can protect a circuit program from unauthorized access
by assigning it a password.
You can only assign or deactivate a password from the IDEC
SmartRelay Base module or from WindLGC. You can only
change a password from the IDEC SmartRelay Base
module. If you have assigned a password, and are using a
Text Display (version 4 or later) together with an IDEC
SmartRelay Base module (version 4 or later), you must enter
this password if you want to change IDEC SmartRelay from
RUN mode to STOP mode from the Text Display. You can
not stop the execution of the circuit program in IDEC
SmartRelay from the Text Display without entering the
password.
