CAUTION!
If the device was not restarted after entering the password or the “password activation time” has not elapsed, this will read
“0” to indicate that password protection is disabled in the “Settings protection” address (modbus adr: 604). In this case,
you don’t need to re-enter the password.
Password activation time resets and restarts each time a modbus write action is performed or a key is pressed.
