7.6.3 Setting items in Account setting
Although the MES interface module supports the basic authentication (account
setting) using user names and passwords, it shall not completely protect the system
from illegal access.
When the programmable controller system security needs to be protected against
illegal access, take measures at the user's discretion.
It is recommended to pay attention to the following:
(a) Set [Account setting] observing the following so that your account (user name,
password) will not be leaked.
1) Prevent any simple setting consisting of alphanumeric characters only, and
include some non-alphanumeric character(s) (e.g. $, &, ?) to create
complicated user name and password.
2) To protect from illegal access using the default account, delete the account
after creating another account.
(b) An account of User name, "QJ71MES96" and Password, "MITSUBISHI" is set by
default.
To protect from illegal access using the default account, delete the account after
creating another account.
