GOT2000 Series

2. Discover new possibilities with two Ethernet ports
1) Design safe and secure network configuration
The information system network in the office is separated from control system network at the production site;
therefore the network architecture is safer and more secure. If a network error occurs in the office by a faulty network
device, production site is not affected.

2) Prevent unauthorized access with two physically
separate networks
Access to the devices in the control system network is not allowed via GOT
from the personal computer in the information system network*. Therefore,
even in the unusual event of unauthorized access to the information system
network, you can reduce the risk of illegal copy or alteration of the data in the
control system network.
* Access is allowed from the engineering software (MELSOFT GX Works3, etc.) using the FA transparent
function (to be supported soon) and from GT SoftGOT using the SoftGOT-GOT link function. When
using the FA transparent function and the SoftGOT-GOT link function, it is recommended to use
them with the IP filter function or set passwords to various project data to enhance security.

Registering the IP address of the
device which is allowed to access
the GOT can prevent the access
from unauthorized devices.

3. 3) Reduce the overall communication load in the network
By separating the network, you can reduce the overall communication load in the network and avoid communication
performance deterioration.

4) Enable visualization at production site
Using two Ethernet ports and the wireless network can offer a wide range of remote solutions for various applications!
The GOT remote solutions increase work efficiency from startup, adjustment, to maintenance with various remote
monitoring and operation functions that use mobile devices and personal computers.

* To use the GOT Mobile function, the GOT Mobile function license (GT25-WEBSKEY) is required separately.
The wireless LAN communication unit (GT25-WLAN) of the GOT can be used as an access point.
* To use the VNC server function, the license (GT25-VNCSKEY) is required separately.
* To use the SoftGOT-GOT link function, the license key (GT27-SGTKEY-U) is required separately.
For the devices that can be connected with GOT when using the Ethernet interface (built-in), the Ethernet communication unit (option), or the
wireless LAN communication unit (option), please refer to the "Connectable device list" on the back cover. For the details of remote monitoring
and operation functions, please refer to the Mitsubishi Graphic Operation Terminal GOT2000 Series Catalog (L(NA)08270ENG).
[Safety precautions]
If remote monitoring and operation functions are used to perform remote control of control equipment, the field operator may not notice the remote
control, possibly leading to an accident. In addition, a communication delay or interruption may occur depending on the network environment,
and remote control of control equipment cannot be performed normally in some cases. Before using the functions to perform remote control, fully
grasp the circumstances of the field site and ensure safety.

number of cascades when using
switching hubs, contact the
switching hub manufacturer.
*2 This depends on the specifications
of the Ethernet network system to
which the GOT is connected. For
the details, refer to the manual
of Ethernet module of connected
programmable controller.
*3 If multiple pieces of network
equipment (including GOT) are
connected within a segment, the
network load would increase. In
such condition, the communication
performance between GOT and
programmable controller may be
declined. The communication
performance may be improved by
the following measures.
•Using switching hubs
•Reducing the number of
monitoring points on the GOT
