Low-cost ICS Testbed - ScadaLTS

The standard set-up is to use the release images of each Raspberry Pi.

Usage of SCADA ScadaLTS

ScadaLTS is not designed to run on a Raspberry Pi. Because of this, it takes some minutes to boot. After this, it is accesible on http.

http://192.168.0.10:8080/ScadaBR

The login is the default login of ScadaLTS admin:admin.

After the login, you can see the current values of the sensors and actuators. Furthermore, the order count is displayed.

With the historian features of ScadaLTS you can view the historic data. For example how the order count changes over time.

Set-up ScadaLTS by your own (optional)

The set-up of ScadaLTS is difficult on a Raspberry Pi. The recommended procedure is to use the release image!

Configure the network interface

Configure IP Adress of the Scada Raspberry Pi.

sudo nano /etc/network/interfaces

The file should look like this at the end. With this, you will have a static IP and if possible also one from DHCP.

# interfaces(5) file used by ifup(8) and ifdown(8)

# Please note that this file is written to be used with dhcpcd
# For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf'

# Include files from /etc/network/interfaces.d:
source-directory /etc/network/interfaces.d

auto lo eth0 eth0:0
iface lo inet loopback

iface eth0 inet dhcp

iface eth0:0 inet static
    address 192.168.0.10
    netmask 255.255.255.0

Install tomcat7

Connect to the Raspberry Pi for the SCADA. Download tomcat in version 7:

wget https://archive.apache.org/dist/tomcat/tomcat-7/v7.0.96/bin/apache-tomcat-7.0.96.tar.gz

Extract the tar.gz archive:

sudo tar xvzf apache-tomcat-7.0.96.tar.gz

Create tomcat directory:

sudo mkdir -p /opt/tomcat
sudo mv apache-tomcat-7.0.96 /opt/tomcat/

Install Java:

sudo apt install default-jdk

Set environment variables:

vim ~/.bashrc

Add the export to the bashrc:

export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-armhf
export CATALINA_HOME=/opt/tomcat/apache-tomcat-7.0.96

Export the bashrc:

. ~/.bashrc

Edit a init.d file to start and stop the tomcat server:

sudo nano /etc/init.d/tomcat

Copy the following to the init.d tomcat file:

#!/bin/sh
# /etc/init.d/tomcat
# starts the Apache Tomcat service
### BEGIN INIT INFO
# Provides:          tomcat
# Required-Start:
# Required-Stop:
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# X-Interactive:     true
# Short-Description: Start/stop tomcat application server
### END INIT INFO
 
export CATALINA_HOME="/opt/tomcat/apache-tomcat-7.0.96"
case "$1" in
start)
  if [ -f $CATALINA_HOME/bin/startup.sh ];
  then
    echo $"Starting Tomcat"
    /bin/su root $CATALINA_HOME/bin/startup.sh
  fi
  ;;
stop)
  if [ -f $CATALINA_HOME/bin/shutdown.sh ];
  then
    echo $"Stopping Tomcat"
    /bin/su root $CATALINA_HOME/bin/shutdown.sh
  fi
  ;;
*)
  echo $"Usage: $0 {start|stop}"
  exit 1
  ;;
esac

Make the init.d script executable:

sudo chmod +x /etc/init.d/tomcat

Add the tomcat script to default startup:

sudo update-rc.d tomcat defaults

Install mysql-server and configure it

Install mariadb as sql server:

sudo apt install mariadb-server
sudo mysql -p

Enter your admin/root password of your server.

Create a sql database for ScadaLTS.

create database scadalts;

Create username and password for ScadaLTS database.

CREATE USER 'scadalts' IDENTIFIED BY 'scadalts';

Give username admin rights to database.

GRANT ALL PRIVILEGES ON scadalts. * TO scadalts;

Exit sql.

quit;

Install the SCADA-LTS WAR App

Change into the directory of the tomcat webapps installation:

cd /opt/tomcat/apache-tomcat-7.0.96/webapps

Get t he current version of SCADA-LTS (do not know, why it is named ScadaBR...):

sudo wget https://github.com/SCADA-LTS/Scada-LTS/releases/download/v2.3.2/ScadaBR.war

Changing configuration of the SCADA-LTS webapp

Edit the environment properties of the SCADA-LTS webapp:

sudo vim /opt/tomcat/apache-tomcat-7.0.96/webapps/ScadaBR/WEB-INF/classes/env.properties

There is already a section, which looks similar to this, delete these elemnts and replace it with the following:

db.type=mysql
db.url=jdbc:mysql://localhost:3306/scadalts
db.username=scadalts
db.password=scadalts
db.pool.maxActive=10
db.pool.maxIdle=10

Importing Data Points and Watch List within SCADA-LTS

Go to the webpage http://192.168.0.10:8080/ScadaBR and select import/export:

Copty the content of the file under config/scadalts.json into the window and select import.
