[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, GS25] Do not touch two points or more simultaneously on the display section. Doing so may operate the switch located around the center of the touched point, 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 and GT25 only): The GOT becomes inoperative. Power on the PLC CPU again to reestablish communication. 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 *1 attacks, computer viruses, and other cyberattacks from unreliable 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 unauthorized access, DoS attacks, 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. 2
