  1. How to secure your Rockwell PLC’s and enforce Software Change Management using MDT AutoSave By Jacques Terblanche Johnson Matthey

  2. Introduction Project Solution Agenda Benefits Considerations Summary

  3. Background to the Project • This project shows how to secure your Rockwell PLC’s at no additional cost using out the box solutions and how to implement software change management on PLC code using MDT’s AutoSave.

  4. Project Goals • Secure all Rockwell SLC and CLX PLC’s from: • Unauthorised online changes • Unauthorised access from a 3’rd party’s PC running PLC Development software • Provide easy configuration to change security access • Implement Software Change Management on PLC Code

  5. Introduction Project Solution Agenda Benefits Considerations Summary

  6. Why AutoSave • A need was identified to perform Software Change Management on all PLC code and to secure all PLC’s from unauthorised access • A comparison was done between MDT AutoSave and Rockwell’s Factory Talk Asset Centre to determine the best solution to provide Change Management as well as securing PLC Processors

  7. Which solution? • AutoSave or Asset Centre? • Change Management • Archive of changes • Scheduled Compares • Locked programs • AutoSave • InTouch Plugin • Archestra Plug-in

  8. Why Software Change Management? • Where is your latest backup • C:\Projects\PLC001 or z:\PLC Backups\PLC001 • Which file is the latest change • 05_03_09_PLC001 or 06_03_09_PLC001 • What was changed? • Uhm can’t remember, that was 2 weeks ago

  9. AutoSave • Central location of all backups • Resides on AutoSave Server • Use normal IT backup methods to backup my backup • Central Location to access all projects • Launch AutoSave Client • Configured in tree structure to easily access projects • Provides a revision history with comments • Enforces comment

  10. New features in AutoSave 5.04 • Spaces • Rearrange tree structure by moving areas and programs • Why is this important • Current structure is flat • Move option allows restructuring of Plant model to represent a S95 model type

  11. FactoryTalk Services Platform • Where to find the Services Platform • RSLinx Classic Optional steps • Install FactoryTalk(R) Services Platform • What is installed • Administration Console • Directory Configuration Wizard • Security Configuration • Emulator • Specify Directory Location

  12. FactoryTalk AdministrationConsole • Used to configure either Local or Network Security • Provides central place to configure: • Users and Groups • Use Local users or Active Directory Groups • Networks and Devices • Configure for entire network • Configure individually • Computers • Add PC Nodes which will be used for Development as well as nodes used to perform remote connections • Policies

  13. Configuring Security • Logix 5000 • Set Administrator to configure Controller Secure • Set Logical Name • Set Controller Security • Logix 500 • Set Controller Security

  14. Enabling Security for Logix 5000 • Install Emulator • Must be installed on all Development PC’s • Enable Security Key • Run SetSectKeys and Enable RSLogix 5000 Security • Controller Properties • Change Security Setting to RSI Security Server • Can be done Online to PLC

  15. Enabling Security for Logix 500 • New install • Select Enable FactoryTalk Security during install • Current Install • Run setup again and select Security option • Securing the Controller • Convert old Logix 500 projects to version 7 or later • Enable Processor Secured from Controller Properties • Download converted project to PLC

  16. Configuring AutoSave for Security Services • Open AutoSave Client • Logon to AutoSave Server • Select PLC • Launch Project • NO CONFIGURATION REQUIRED

  17. What now? • Windows user authenticated to Security Server • Local Users • Domain users • User with development privileges • User with read only privileges

  18. Topology - Software • The AutoSave system consists of: • AutoSave Server • 2003 Server • SQL 2000 SP4 • AutoSave 5.04 • FactoryTalk Services Platform – Network Security • AutoSave Agents • 2003 Server • Logix 500 and 5000 • One Logix 5000 agent and one Logix 500 agent • FactoryTalk Services Platform – Referencing AutoSave Server • AutoSave Development clients • XP SP2 Pro • Logix 500 and 5000 • FactoryTalk Services Platform – Referencing AutoSave Server

  19. Topology - Network

  20. Topology – Use of Agents • Remote connection enabled • User starts a Terminal Session • Allows multiple users access to AutoSave • Less development software installations

  21. Introduction Project Solution Agenda Benefits Considerations Summary

  22. Benefits / Goals Achieved • Were the initial goals achieved? • Secure all Rockwell PLC’s – YES • Provide Software Change Management - YES • What benefits? • PLC Online connection is read only • No Online changes possible • No offline changes possible • No access via unauthorised Development software

  23. Introduction Project Solution Agenda Benefits Considerations Summary

  24. Lessons Learned • SLC projects must be converted to the latest Logix 500 version • Cannot access PLC’s if Security Server is unavailable • Install and configure secondary security server for emergencies

  25. Introduction Project Solution Agenda Benefits Considerations Summary

  26. Conclusions • It is essential to have the correct tools available to perform Software Change Management • MDT AutoSave provides an easy interface with all the functionality. • Securing your Rockwell PLC’s is quick and easy using the Factory Talk Service Platform

  27. The End....
