What is SCADA?

SCADA (Supervisory Control and Data Acquisition) is defined as

the monitoring and control of technichal processes by means of a computer system

(translated definition from German wikipedia)


What is SCADA?


What is Eclipse SCADA?

■ In short: Eclipse SCADA is an implementation of a SCADA system based on the Java platform

■ an open source SCADA platform■ protocol implementations, server components,

client libraries, …

■ some utility projects■ tooling

■ ESAC, configurator, ...


Eclipse SCADA – Goals

■ to provide a comprehensive, state of the art SCADA system, built on modern technologies and open to interface with as many other systems as possible

■ allow easy integration between hardware (field devices) and business applications (e.g. ERP)

Featuresa high level overview


Features

■ Data Acquisition (DA)■ Alarms & Events (AE)■ Historical Data (HD)■ Configuration (CA)■ GUI/HMI (VI)


Features

■ Data Acqusition (DA)■ deals with »real-time« (not hard real-time!) data■ handles single scalar values

■ Alarms & Events (AE)■ handles process alarms, operator actions,

responses generated by the system, informational messages, auditing messages


Features

■ Historical Data (HD)■ deals with recording values (provided by DA) and

archiving these for later retrieval

■ Configuration (CA)■ handles creation of configurations for the server

components, reconfiguration of the running system

■ GUI/HMI (VI)■ provides GUI components, based on Draw2D


Features

■ central to all functions: DA (Data Access)■ all other functionality is based on the values

provided by it

Data Acquisition


Supported Protocols I

■ Modbus■ Siemens S7■ “exec” (shell script execution)■ JDBC■ REST■ MQTT■ A custom Arduino UDP protocol


Supported Protocols II (through openSCADA)

■ OPC DA 2.0 (Utgard; can't be included with Eclipse SCADA because of licensing issues)

■ IEC 60870-5-104 (will be reintegrated with Eclipse SCADA in release 0.3)

■ SNMP (will be integrated with Eclipse SCADA in release 0.3)


Supported Protocols III (export)

■ Modbus■ IEC 60870-5-104 (through openSCADA)■ MQTT■ REST


The path of a value from sensor to HMI

■ Modbus Driver (DA server interface)■ Master Server (DA client + DA server interface)■ GUI (DA client interface)

■ A Driver talks to the field device in the protocol it understands (for instance: Modbus) and converts it to the Eclipse SCADA internal protocol “ngp”

■ A driver usually runs in its own process to allow a independent restart if something goes wrong

■ The master server uses ngp to communicate with the driver■ Within the master server the items are enriched with

additional functionality■ The items are then exported via ngp again

Alarms & Events


Alarms & Events (AE)

■ Alarms are realized through a state machine, we call it “monitor”■ Only current state

■ State change (might create) Event→■ States:

■ OK NOT_OK + (ACK required / ACK not required)↔

■ Base Priorities:■ OK, WARN, ALARM

■ Demotion:■ ALARM WARN→



■ Monitor Implementations:■ Level Monitor (Min, LL, L, H, HH, Max), as local and

remote variant■ Bit Monitor■ List Monitor■ Script Monitor



■ Alarms (Monitor states) are transient■ Events are stored permanently (in SQL Database)■ Event has some common properties, and any

number of custom ones■ Events are held in configurable buffer (pool) to

supply client immediately with latest ones■ Past events can be queried using simple ldap like

syntax

Historical Data


Eclipse SCADA – Historical Data (HD)

■ Update on live values■ Storage abstracted■ At the moment a file system based storage is

available■ Can keep actual values, without interpolation,

for some time■ Comprehension after defined timespan


Visual Interface


Visual Interface

■ Declarative UI using EMF■ Scriptable with Javascript■ Only a few entry points to remember

(onUpdate, onInit, …)■ Component based Symbol editing■ Properties are propagated to the innermost

element■ Simple but very flexible




Visual Interface

■ Wizard which creates a skeleton project including maven pom file for easy build

Configuration & Deployment



■ Configuration framework based on EMF■ Split between infrastructure model (nodes and

services) and component model (hierarchical representation for the end user)

■ Configuration can be updated at runtime■ Creation and deployment is separated■ ESAC used for updating the configuration

■ Configuration changes can be minimized through applying only diff!



■ Create complete installable packages from IDE■ Debian packages for Debian & Derivates■ RPM packages for Redhat and SuSE■ MSI files for Windows

■ Allows start of SCADA servers from IDE


Other interesting features


Other Interesting Features

■ Support of cryptographically signed user actions (e.g. acknowledgement, setting manual values, etc) using a PKI■ Also supports user elevation

Q&A


FAQ

■ Do you have a web interface?■ We don't have a standard solution for a web interface yet.

Our HMIs are based on Eclipse RCP

■ Do you have support for OPC UA/IEC 62541?■ No, but if somebody sponsors the development, we would

love to implement it as a clean room implementation of IEC 62541

■ Why don't you use MQTT natively?■ A couple of features we support just can't be realized with

MQTT (e.g. our callback functionality)

A short History


A short History

■ started 2006 as openSCADA■ main emphasis: connectivity to legacy

hardware■ after that more and more functionality added■ since then, most used part of the project by

developers: Utgard library, a platform agnostic library to access OPC DA 2.0 servers■ (not part of Eclipse SCADA!)


A short History

■ June 2013■ Eclipse SCADA proposed (based on openSCADA)

■ Juli 2013■ IBH SYSTEMS GmbH becomes Eclipse foundation

member

■ September 2013■ officially incubator project


A short History

■ April 2014■ First official release 0.1.0■ Finale of migration■ Configuration

■ January 2015■ 0.2.0 release■ Much improved tooling (preview, servers within IDE)

Roadmap


Eclipse SCADA Roadmap

■ Planned: 2 releases per year■ 0.3 (1st quarter of 2015)

■ Integration of SNMP driver and reintegration of IEC 60870-5-104

■ 0.4 (3rd quarter of 2015)■ Mostly improvements:

■ Performance, Memory■ Tooling, IDE integration■ Based on Eclipse Mars

Thank you for your attention!

Glossary


Glossary

■ Driver (DA)■ a protocol adapter, converts device specific protocol

(for instance modbus) into the Eclipse SCADA protocol(s) (for instance ngp)

■ Tag, Item, Data Point, DataItem■ a singular scalar value provided by a device or

server, identified by a name


Glossary

■ Field Device■ controls local operations such as opening and

closing valves and breakers, collecting data from sensor systems (for instance a data logger or a PLC), speaks some protocol

■ Master Server (DA, AE, [HD])■ central server component, provides additional

functionality based on DataItems such as alarm →generation
