2 Overview
Under the catchword "Industry 4.0", more and more new communication and information
technologies are finding their way into industrial automation. In order to be able to
implement these requirements efficiently and as quickly as possible, attempts must be
made to reduce the high level of complexity through modularisation and standardisation.
In this context, OPC UA has proven to be a forward-looking communication standard.
This is because OPC UA fulfils the Industry 4.0 requirement for independence from
manufacturer, industry and operating system communication.
Since OPC UA not only transmits machine data, i.e. process values and measured
values, but can also describe them semantically, OPC UA is becoming increasingly
important when it comes to transferring machine data from controllers to higher-level
systems.
One solution for reading process data from Mitsubishi Electric controllers and robots that
do not have an OPC interface as standard is the RD55UP12-V module with installed IBH
Link UA software, called IoT Gateway.
This solution is a server/client module. The OPC client function also enables OPC servers
to exchange data with each other. For example, controllers or other devices with OPC UA
from different manufacturers can exchange data via this function.
Communication with the controller is via TCP/IP.
The IoT Gateway has an Ethernet port for the machine level and an Ethernet port for the
control level.
Only OPC accesses are possible on the control level. A firewall is integrated between the
two levels. The ports are configured via the GX-Works3 programming software of the iQ-R
CPU.
2.1 System structure
As a minimum configuration, the IoT Gateway always requires a base rack, an iQ-R CPU
and the RD55UP12-V module. To establish a connection to several controllers, a switch is
required at the process level.

2.2 Security
The IoT Gateway has a certificate management for secure communication. A corresponding
software interface is supplied for this purpose, which can be displayed in any web browser.
The configuration of the security levels and the administration of the certificates are carried
out in this interface. This is based on the mechanisms defined by the OPC Foundation. OPC
UA Security includes authentication and authorisation, encryption and data integrity through
signing. In this way, the control system can be protected against uncontrolled access via a
higher-level system.
2.2.1 Encryption
There are different levels of encryption (Encrypt): None, Basic128Rsa15 and Basic256.
None
No encryption
Basic128Rsa15
128 bit encryption
Basic256
256 bit encryption
The IBH Link UA function supports the Level Sign and SignAndEncrypt
None
No security level, fastest data transmission
Sign
The messages contain signed certificates
Sign and Encrypt
The messages contain signed certificates and are encrypted
Sign + Sign and
Encrypt
The messages may contain only signed certificates, or can be
signed and are encrypted as well
2.2.2 Certificates
Another security level of OPC UA is the exchange of certificates. Communication is only
possible when both server and client have been assigned a valid certificate by the respective
partner.

3 Commissioning
Each RD55UP12-V can be started as an IoT Gateway module. For this purpose, a
corresponding image must be written to an SD card.
The image file contains the Linux operating system and the corresponding programme from
IBH for the OPC UA server function.
In order to be able to use the OPC UA server function without restriction, it must be activated
for the hardware used with a licence code created at IBH. For this purpose, the serial
number and MAC addresses from the type plate of the module are required.

In addition, a web browser must be installed on the PC.
If you have received an already configured IoT Gateway from Mitsubishi Electric, the
following setup chapters 3.2 to 3.5 are not required.
For your security, we recommend that you create a backup copy of the inserted SD card, as
described in Chapter 3.6.
3.2 Prepare SD card
To write the image file with the Linux OS to an SD card, you need the programme "DDWIN"
on a Windows computer. After downloading, the ZIP file must be unpacked, an SD card
inserted into the PC and the file "DDWIN.EXE" executed as administrator.
1. Select the SD card in the PC under "Choose disk".
2. Select the Linux image file from IBHsoftec under "Choose file".
3. Select "<<Restore>>".

Date: 01/02/2022 9
When writing to the SD card is finished, the "DDWIN" program can be closed and the SD
card removed from the PC and inserted into the RD55UP12-V module.
3.3 Prepare hardware
Unpack the selected iQ-R hardware, mount it to the base rack and connect it as instructed
(refer to Mitsubishi Electric hardware manuals). The control unit can now be switched on.
3.4 Set IP addresses for RD55UP12-V IBH
First, you have to create a project in GW-Works3 that matches the hardware you have
plugged in.
Under "Parameters" →"Module Information" →RD55UP12-V "→Basic Setting" →"Own node
setting" the IP addresses for the control and process level can then be set.

Once all settings have been made, the new project is transferred to the CPU. The control
unit must be switched off and on again once after the transfer.
The channel "CH1" of the RD55 module is now in the address range of the management
level and the channel "CH2" is in the range of the control level.
3.5 IoT Gateway OPC UA Server Setup
3.5.1 Launch web interface
Depending on the level via which the PC is connected to the IoT Gateway, the
parameterisation interface can be called up by entering the corresponding IP address in a
web browser.
In the following example, the PC is connected via the process level, only "192.168.0.3" is
entered in the browser.
The login screen is displayed. For a new system, the default user name and password are
both "admin".

After pressing "Log in", you are in the configuration interface.
3.5.2 Activate licence code
After you have received the license file from IBHsoftec matching the module serial number
and MAC addresses, this must be imported into the module once.
To do this, select the "System" menu in the configuration interface.

_________________________________________________________________________

Date: 01/02/2022 12
On this page, click on "Browse" at "Select licence file" to search for the corresponding file
and then click on "Upload licence file" to copy it to the SD card.
After a restart of the system, the IoT Gateway can be used without restrictions.
The basic set-up of the IoT Gateway is now complete. The individual functions are explained
in the following chapters.
3.6 Backup / Restore of SD card
After all the necessary configurations have been made and the project functions have also
been parameterized, a backup copy can be created from the SD card using the "DDWIN"
software. This backup can only be used in the RD55UP12-V module with the hardware ID
for which the IoT Gateway license was created.
3.6.1 Create Backup
To create the backup, switch off the controller with the IoT Gateway and remove the SD card
from the IoT Gateway module. Insert the SD card into the PC and run the "DDWIN.EXE"
program as administrator.
1. Select the SD card in the PC under "Choose disk"
2. Select a drive path under "Choose file" and enter the desired file name
3. Select „>>Backup>>“

The data will now be read from the SD card
The SD card can now be reinserted into the IoT Gateway and the controller can be started.
3.6.2 Restore the SD card
To load the image onto a new SD card, the "DDWIN.EXE" program must be run as an
administrator
Then insert a new SD card into the PC

1. Select the SD card in the PC under "Choose disk"
2. Select the previously created backup copy under "Choose file".
3. Select „<<Restore<<“
After the message "Writing has completed ..." the SD card can be plugged into the
corresponding RD55UP12-V module and then the controller can be switched on.
4 OPC UA server function
This chapter explains how to connect the IoT Gateway to controllers and make their global
variables available as OPC UA tags for clients.
4.1 iQ-R CPU
4.1.1 Configure SLMP Connection
In order for the Mitsubishi controller to be accessible via OPC UA, the SLMP Connection
Module must be inserted using the GX Works configuration software.
Important: In order for data to be written externally to the OPC UA tags, "Enable all (SLMP)"
must be selected!
