  1. Denis Ulybyshev dulybysh@purdue.edu Open-source SCADA systems SCADA Open Source Solutions By Denis Ulybyshev

  2. Overview of current SCADAs

  3. Limitation on the number of equipment connected (IGSS) Limitation on the number of variables (SIELCO) Limitation on the number of hardware protocols supported Main drawbacks of open-source SCADAs

  4. openSCADA: Analog Data Visualization

  5. openSCADA: communication with ARDUINO

  6. openSCADA: Simple Visualization Screen Visualization of discrete and analog variables

  7. openSCADA: list of Alarms

  8. IGSS System requirements Hardware requirements • IGSS requires a Pentium 2 Ghz PC or equivalent. • Memory requirements are related to the size of the IGSS database, screen resolution and concurrent use of other software packages. It is recommended that at least 1Gb is available for IGSS. • Graphics card supporting true color graphics (min. 24 bit). • At least one free parallel or USB port on the server PC must be available for the IGSS dongle for licensed systems. (Soft-lock has been an option since version 9). Software requirements • 32bit & 64bit of:: Windows 7, Windows 2010 Server, Windows 2008 Server, Windows Vista, Windows XP, Windows 2003 Server. • 32bit Microsoft Excel 2007 or higher (required to design custom reports, Data to Excel and IGSS Real-Time Data).

  9. OpenSCADA • Data acquisition from hardware of manufacturer “ICP DAS” and others. • Providing data to upper-level systems: • By means of interfaces: • Serial interface (RS232, RS485, Modem, ...), by helps of transport module Serial. • IP-networks sockets and network levels protocols TCP, UDP and Unix, by helps of transport module Sockets. • Security sockets layer (SSL), by helps of transport module SSL. By means of protocols: • Self OpenSCADA protocol, by helps of transport's protocol module SelfSystem. • ModBUS family protocol (TCP, RTU and ASCII), by helps of transport's protocol module ModBUS. • "OPC UA" protocol, by helps of transport's protocol module OPC UA. • Simple special protocols, developed by users by helps of transport's protocol module User Protocol.

  10. Conclusion Summary: • 3 open-source SCADAs are presented (out of 6-7 popular) • openSCADA supports ARDUINO hardware • openSCADA supports SNMP, OPC, relational DB; Client-server architecture. Development under Eclipse IDE (interfaces can be written in JAVA). • To design SCADA-level we must have the full-picture of hardware used (number of controllers, sensors etc), protocols used and the full list of signals (variables) ...
