Procedure
1) SD Card Setup
Please image the following file onto an SD card. The CPU module supports SDHC 4GB to 32GB. The
recommended SD card is a SanDisk Memory Card.
a. Download balenaEtcher.
b. Un-zip and extract the “eRT3 + Sushi Sensor Application” folder to a desired location.
c. Login or create an account on the Yokogawa Customer Portal.
d. Please locate the latest SD card image and click on the file to download it. You can navigate
from the homepage to “[Useful Links]” “PLC/PAC & Embedded Controller” > “OS-free CPU
module OS image Download” > “Agree” > “OS image for F3RP70”
“rp70_OS_Image_R211.zip”.
OR click on the following link.
e. Use a SD card reader to insert the SD card into the PC.
f. Open balenaEtcher. Select the OS image. Select target (SD card). Select Flash!
g. You may now insert the SD card into the SD1 slot of the e-RT3.
2) Setting up the Cloud
a. Create an account on InfluxDB Cloud. Use the official InfluxDB website for more information.
b. Fill out the prompts for company and organization after logging in. My company name is “Yokogawa Corporation of America”. My organization name is “eRT3”. Make sure to select the correct region for the server. I selected “US East”.
c. Choose the “Free” plan.
d. Once you have reached the dashboard, go to “API Tokens”.
e. Select “Generate API Token” > “All Access API Token”. Enter a description for the API Token. Click “Save”.
f. Please copy and paste the custom API token into a safe location where you can access it in the future.
g. Navigate to “Load Data” > “Buckets” from the side bar.
h. Click on “Create Bucket” and name the bucket “sushiSensor”. If you are on the free version, keep the “Data Retention Preferences” as “30 days”. Click “Create”.
i. Please note down the server address located in your URL bar. You can learn more about your cloud region here. For example, if you live in the US East, please note down: https://us-east-1-1.aws.cloud2.influxdata.com/.
3) Configuring the Network
To configure the network and change IP addresses of various devices, the PC IP address will need to be within the same network as the device it is communicating with. This will involve changing the PC IP address various times using the following steps:
a. Go to your PC’s “Control Panel” > “Network and Internet” > “Network Connections”. Select the Ethernet connection to the router.
b. Double-click on “Properties”.
c. Double-click “Internet Protocol Version 4 (TCP/IPv4)”.
d. Select “Use the following IP address:”.
e. Change the PC IP address to one that is in the same network as the device’s address. For example, the default e-RT3 IP address is 192.168.3.72. Therefore, the PC address would need to be changed to 192.168.3.X (you may choose anything for X that has not already been assigned). Make the Subnet mask 255.255.255.0 (smaller network).
Changing the e-RT3 IP address
a. On the physical device itself, check to see if the e-RT3 is on Command Mode: 0 (the arrow should be pointing to 0). Make sure the e-RT3 is mounted to the Base module and is being powered through the Power Supply module. Refer to IM 34M06M52-25E for more details.
b. Using an ethernet cord, connect the PC directly to LAN1 of the e-RT3.
c. Change the PC IP address to one that is in the same network as the e-RT3 (Use Ex: 192.168.3.3).
d. This manual will be using Windows PowerShell as its terminal. If not already installed on your PC, please use the following link to install or find an alternative terminal.
e. Wait until the display on the e-RT3 lights up “OS” under “BAT”. This means that the operating system is now running. If you try to SSH before the “OS” appears, it will not work.
f. SSH into the e-RT3 using the following commands:
ssh ert3@192.168.3.72
When prompted for the password, type (note: the typing will be invisible):
user_ert3
g. (Optional): If you have used this SSH key before and it notifies you that remote host identification has changed, you may need to locate and open your “known_hosts” file (may be located in the .ssh folder) in a text editor and remove the all the lines that includes the IP address and the key (corresponding to 192.168.3.72). You can then save the “known_hosts” file and attempt to SSH again. This time you will be prompted to add and confirm a new host key to the “known_hosts” file. Type “yes” if prompted.
h. To make sure the DNS servers are specified, we need to change the resolved.conf file. Type the command:
sudo nano /etc/systemd/resolved.conf
When prompted for the password, type (note: it will be invisible):
user_ert3
i. Once the file opens in the terminal, uncomment the DNS and Fallback DNS lines by deleted the “#” and add the Google DNS server addresses as shown below. Please note there is a space between “8.8.8.8” and “8.8.4.4”:
[Resolve]
# Some examples of DNS servers which may be used for DNS= and FallbackDNS=:
# Cloudflare: 1.1.1.1 1.0.0.1 2606:4700:4700::1111 2606:4700:4700::1001
# Google: 8.8.8.8 8.8.4.4 2001:4860:4860::8888 2001:4860:4860::8844
# Quad9: 9.9.9.9 2620:fe::fe
DNS=8.8.8.8 8.8.4.4
FallbackDNS=8.8.8.8 8.8.4.4
#Domains=
#DNSSEC=no
#DNSOverTLS=no
#MulticastDNS=yes
#LLMNR=yes
#Cache=yes
#DNSStubListener=yes
#DNSStubListenerExtra=
#ReadEtcHosts=yes
#ResolveUnicastSingleLabel=no
j. On your keyboard, use the shortcut “ctrl + s” to save and then “ctrl + x” to exit the program.
k. Restart systemd-resolved:
sudo systemctl restart systemd-resolved
l. To change the IP address for LAN1, we need to change its network configuration file:
sudo nano /etc/systemd/network/10-eth0.network
If prompted for the password, type (note: it will be invisible):
user_ert3
m. Once the file opens in the terminal, change the text in the file so that it matches to the routes below:
[Match]
Name=eth0
[Network]
Address=192.168.2.72/24
[Route]
Gateway=192.168.2.1
Destination=192.168.2.0/24
[Route]
Gateway=192.168.2.1
Destination=0.0.0.0/0
n. On your keyboard, use the shortcut “ctrl + s” to save and then “ctrl + x” to exit the program.
o. Restart systemd-networkd:
sudo systemctl restart systemd-networkd
p. Turn the e-RT3 off and on. The e-RT3 and PC are now on the same network and the e-RT3 has internet access.
q. (Optional): Change the PC IP address to one that is in the same network as the e-RT3 (Ex: 192.168.2.3). Ping 192.168.2.72 to make sure the PC and the e-RT3 are now on the same network:
ping 192.168.2.72
If you can send and receive packets successfully, the setup is correct.
r. You may now remove the ethernet cord.
Changing the Gateway IP address
If further information is needed to set up the Gateway, please refer to TI01W06A51-50EN.
a. Using an ethernet cord, connect the PC directly to the Gateway.
b. Change the PC IP address to one that is in the same network as the Gateway (Ex: 192.168.2.3). The default IP address of the Gateway is 192.168.2.1.
c. Access the Gateway web-browser by entering “192.168.2.1” into the URL bar.
d. An error message may appear but click on “Advanced” > “Proceed to 192.168.2.1 (unsafe)”.
e. Login into the Gateway web-browser with the following default username and password:
Username: admin
Password: Yokogawa1
f. On the left side of the dashboard, select “Setup” > “Network Interfaces”.
g. Click the pen under “Options” to edit the IP address visible under the name “br0”.
h. Change the IP address to 192.168.2.4 and hit “Submit”.

j. The Gateway IP address is now changed. Give the web-browser some time to restart. Access the web-browser now at https://192.168.2.4:1880/ in the URL bar.
k. You may now remove the ethernet cord.
Changing the router IP address
This procedure is for the CyberTAN Technology router WR214E. Please refer to your own router’s manual if different.
a. Using an ethernet cord, connect the PC directly to one of the ports of the router. Make sure the router is connected to the internet and is powered.
b. Reference your router’s manual to change its IP address. For example, the router in this setup, WR214E, has a default web-browser of http://192.168.1.1 and a default username and password: admin. You will need to change the PC IP address to one that is in the same network as the router temporarily (Ex: 192.168.1.2).
c. After changing the router IP address (to 192.168.2.1) and applying the changes within the web-browser, turn the router off and on.
d. Change the PC IP address to one that is in the same network as the router (Ex: 192.168.2.2). You can now access the router web-browser at http://192.168.2.1.
e. You may now remove the ethernet cord.
4) Wiring Connections
a. Please connect all devices to the same network via the router. The PC, LAN1 of the e-RT3, and Gateway can all plug into the router with an ethernet cord. The router needs to connect to an ethernet cable wired with internet connectivity. Make sure all devices are powered. The PC is only optional after the application is setup.
5) e-RT3 Dependencies
A couple of different dependencies will need to be built on the e-RT3: NVM (Node Version Manager), Node.js, npm, Node-RED, Grafana. To interact with the e-RT3, you will need to SSH into it and continue to work in PowerShell.
