When using an intranet environment through a global address, connecting to an
unauthorized terminal such as a SCADA, HMI or to an unauthorized server may result in
network security issues such as spoofing and tampering. You must take sufficient measures
such as restricting access to the terminal, using a terminal equipped with a secure function,
and locking the installation area by yourself.
When constructing an intranet, communication failure may occur due to cable disconnection
or the influence of unauthorized network equipment. Take adequate measures, such as
restricting physical access to network devices, by means such as locking the installation
area.
When using a device equipped with the SD Memory Card function, there is a security risk
that a third party may acquire, alter, or replace the files and data in the removable media by
removing the removable media or unmounting the removable media.
Please take sufficient measures, such as restricting physical access to the Controller or
taking appropriate management measures for removable media, by means of locking the
installation area, entrance management, etc., by yourself.
