Installing Ignition Edge on Moxa UC-8100A

Configure device to have a fast network connection.

If you're unit has ThingsPro on it, all configuration is done using the web interface on the bottom/second ethernet port.

Connect to it and access https://192.168.4.127 to access the interface.

Connect via SSH using the login (root/moxa) and run the following:

sudo apt update
sudo apt upgrade -y
sudo apt install unzip fontconfig

Copy the installation zip file to /home/moxa using WinSCP or download it with the below command:

cd /home/moxa
curl -L -O -H 'Referer: https://inductiveautomation.com/downloads/ignition' https://files.inductiveautomation.com/release/ia/8.1.17/20220512-1059/Ignition-Edge-linux-armhf-32-8.1.17.zip

If upgrading from an older version, stop the existing Ignition instance, remove the service, and delete the lib and webserver/webapps folders.

sudo /usr/local/bin/ignition/ignition.sh stop
sudo /usr/local/bin/ignition/ignition.sh remove
sudo rm -rf /usr/local/bin/ignition/lib
sudo rm -rf /usr/local/bin/ignition/webserver/webapps

Unzip the file to the /usr/local/bin/ignition folder using the following command and delete the old file:

cd /home/moxa
sudo unzip -o -d /usr/local/bin/ignition Ignition-Edge-linux-armhf-32-8.1.17.zip
rm Ignition-Edge-linux-armhf-32-8.1.17.zip

Change the directory to the Ignition installation and make the relevant files executable using the following commands:

cd /usr/local/bin/ignition
sudo chmod +x ignition-gateway
sudo chmod +x *.sh

If upgrading from an older version, upgrade the runtimes using the following command:

sudo /usr/local/bin/ignition/ignition.sh checkruntimes

If the upgrade is a major upgrade (8.0 to 8.1), run the upgrader to update the ignition.conf file using the following command:

sudo /usr/local/bin/ignition/ignition.sh runupgrader

Install Ignition as a service with the following command:

sudo /usr/local/bin/ignition/ignition.sh install

If using a serial port for communications, edit the Ignition-Gateway.service file to start up after the Moxa Modbus Gateway service:

sudo nano /etc/systemd/system/Ignition-Gateway.service

Modify the After line to match this:

[Unit]
Description=Ignition-Gateway
After=mxmodbusgateway.service

[Service]
Type=forking
ExecStartPre=/bin/sleep 30
ExecStart=/usr/local/bin/ignition/ignition.sh start sysd
ExecStop=/usr/local/bin/ignition/ignition.sh stop sysd
KillMode=process

[Install]
WantedBy=multi-user.target

Then reload the service control daemon to pick up the changes and start the service:

sudo systemctl daemon-reload
sudo service Ignition-Gateway start

On the Moxa's it seems they have a bug that doesn't allow the NTP service to keep correct time on the unit.

If you run the following command and it doesn't show the service is running and gives a warning or error, it's most likely broken:

sudo service systemd-timesyncd status

This can be fixed by removing executable permissions on the /usr/sbin/ntpd file with the following command:

sudo chmod -x /usr/sbin/ntpd

Then you need to either reboot or start the time synchronization service with the following command:

sudo service systemd-timesyncd start
