[DESIGN PRECAUTIONS]
WARNING
● The display section of the GOT is an analog-resistive type touch panel.
When multiple points of the display section are touched simultaneously, an accident may occur due to
incorrect output or malfunction.
[GT27]
Do not touch three points or more simultaneously on the display section. Doing so may cause an
accident due to an incorrect output or malfunction.
[GT25, GT23, GT21]
Do not touch two points or more simultaneously on the display section.
Doing so may cause a touch switch near the touched points to operate unexpectedly, or may cause
an accident due to an incorrect output or malfunction.
● When programs or parameters of the controller (such as a PLC) that is monitored by the GOT are
changed, be sure to reset the GOT, or turn on the unit again after shutting off the power as soon as
possible.
Not doing so can cause an accident due to false output or malfunction.
● If a communication fault (including cable disconnection) occurs during monitoring on the GOT,
communication between the GOT and PLC CPU is suspended and the GOT becomes inoperative.
[For bus connection (GT27, GT25 Only)]
The CPU becomes faulty and the GOT becomes inoperative.
[For other than bus connection]
The GOT becomes inoperative.
A system where the GOT is used should be configured to perform any significant operation to the
system by using the switches of a device other than the GOT on the assumption that a GOT
communication fault will occur.
Not doing so can cause an accident due to false output or malfunction.
● To maintain the security (confidentiality, integrity, and availability) of the GOT and the system against
unauthorized access, DoS
networks and devices via network, take appropriate measures such as firewalls, virtual private
networks (VPNs), and antivirus solutions.
Mitsubishi Electric shall have no responsibility or liability for any problems involving GOT trouble and
system trouble by DoS attacks, unauthorized access, computer viruses, and other cyberattacks.
*1 DoS: A denial-of-service (DoS) attack disrupts services by overloading systems or exploiting
vulnerabilities, resulting in a denial-of-service (DoS) state.
