[DESIGN PRECAUTIONS]
WARNING
●Some failures of the GOT or cable may keep the outputs on or off. Some failures of a touch panel may
cause malfunction of the input objects such as a touch switch. An external monitoring circuit should be
provided to check for output signals which may lead to a serious accident. Not doing so can cause an
accident due to false output or malfunction.
●Do not use the GOT as the warning device that may cause a serious accident. An independent and
redundant hardware or mechanical interlock is required to configure the device that displays and
outputs serious warning. Not doing so can cause an accident due to false output or malfunction.
●When the GOT backlight has a failure, the GOT status will be as follows.
Failure to observe this instruction may result in an accident due to incorrect output or malfunction.
[GS25]
The POWER LED blinks (orange/blue), the display section dims, and inputs by a touch switch are
disabled.
[GS21]
The POWER LED blinks (orange/blue), and the display section dims. However, inputs by a touch
switch are still available.
The GOT backlight failure can be checked with a system signal of the GOT.
Even if the display section dims, inputs by a touch switch may still be available. This may cause an
unintended operation of the touch switch.
For example, if an operator assumes that the display section has dimmed because of the screen save
function and touches the display section to cancel the screen save, a touch switch may be activated.
WARNING Indicates that incorrect handling may cause hazardous
conditions, resulting in death or severe injury.
CAUTION
Indicates that incorrect handling may cause hazardous
conditions, resulting in medium or slight personal injury or
physical damage.

[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.
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. 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.

[DESIGN PRECAUTIONS]
CAUTION
●Do not run the control line cables and communication cables together with or near the main circuit
cables, power line cables, or other cables.
Keep a distance of 100 mm or more between them as a guide.
Not doing so may cause a malfunction due to noise.
●Do not press the GOT display section with a pointed material as a pen or driver. Doing so can result in
a damage or failure of the display section.
●When the GOT connects to an Ethernet network, the IP address setting is restricted according to the
system configuration.
[GS25]
When a GS25 model and a GOT1000 series model are on an Ethernet network, do not set the IP
address 192.168.0.18 for the GOTs and the controllers on this network.
Doing so can cause IP address duplication at the GOT startup, adversely affecting the communication
of the device with the IP address 192.168.0.18.
The operation at IP address duplication depends on the devices and the system.
[GS21]
Setting the IP address (192.168.3.18) in the following system configurations can cause IP address
duplication at GOT startup, adversely affecting communications of the device whose IP address is
192.168.3.18.
The operation at IP address duplication depends on the devices and the system.
When multiple GOTs connect to the Ethernet network: Do not set the IP address (192.168.3.18) for
the GOTs and the controllers in the network.
When one GOT connects to the Ethernet network: Do not set the IP address (192.168.3.18) for the
controllers other than the GOT in the network.
●When using the Ethernet interfaces, set an IP address for each interface to access a different
network.
●Turn on the controllers and the network devices to be ready for communication before they
communicate with the GOT. Failure to do so can cause a communication error on the GOT.
●When the GOT is subject to shock or vibration, or some colors appear on the screen of the GOT, the
screen of the GOT might flicker.
