Plant SCADA 2020 R2 Release Notes

Note:
The following features are no longer supported with this release of Plant SCADA.

• EcoStruxure Web Services (EWS) are no longer supported. You will not be able to create or use an EWS server or client.

• The Vijeo Web Gate Control has been deprecated and is no longer part of the Plant SCADA installation. The control will still work with Plant SCADA. However, to continue to use it you will need to manually reinstall it from another source as it will have been uninstalled when the previous version of Citect SCADA was uninstalled.

• The Pelco ActiveX Control has been deprecated and is no longer part of the Plant SCADA installation. If you have upgraded your computer from a previous version with this control installed, it will continue to function. However, it is recommended that you communicate with Pelco cameras using a different method.

New features and enhancements

• Rebranding to Plant SCADA

  The 2020 R2 release signifies the transition away from the Citect SCADA brand to AVEVA™ Plant SCADA. The new name reflects the positioning of Plant SCADA within the broader family of AVEVA products.

  The rebranding incorporates several changes, including updates to splash screens and graphics, icons, installer and installation directories, start menu paths, and more.

  To determine the new directory locations, see View a Project's Folders.

• Integration of AVEVA™ Industrial Graphics

  AVEVA Industrial Graphics is the common graphics technology used across AVEVA's SCADA, HMI and cloud solutions. You can create HTML5 screens and dashboards in Plant SCADA and access them in desktop browsers and mobile devices.

  Note:
  AVEVA Industrial Graphics is now deprecated within Plant SCADA and future releases. It will no longer be supported or maintained in Plant SCADA 2023, Plant SCADA 2023 R2, future versions, monthly updates or security updates.
  • AVEVA recommends customers cease using AVEVA Industrial Graphics within Plant SCADA runtime systems and decommission any Plant SCADA Industrial Graphics web servers from production and engineering systems.
  • The parameter [General]EnableIndustrialGraphics has been provided in Plant SCADA 2023 Update 29 (delivered in October 2025), to allow you to disable Industrial Graphics functionality within Plant SCADA configuration tools. It is recommended that you manually set this parameter to disabled (0) in your Citect.ini file on any Plant SCADA computers within your production and engineering systems.
  See the Knowledge Base article 000103614 Security advice regarding AVEVA Industrial Graphics and Plant SCADA on the AVEVA Knowledge & Support Center for more information.

• Integrated OPC UA Server Functionality

  You can now make your I/O data accessible to third-party systems with the new OPC UA Server. This enables IT and OT convergence through secure connectivity.

  For more information, see Install an OPC UA Server.

• IPv6 Support

  Plant SCADA now supports Internet Protocol version 6 (IPv6) and will accept 128 bit IP addresses (including any acceptable abbreviations). For example:

  • 2001:0db8:0000:0000:0000:8a2e:0123:1234

    or

  • 2001:db8::8a2e:123:1234 (abbreviated).

    You can now operate a Plant SCADA system on an IPv6 network. IPv6 protocol can be used for communication between servers and clients, and for any drivers that support IPv6.

    IPv6 support can be enabled via the Network Model page of the Setup Wizard.

    See Add Network Addresses and Server Redirection Using Address Forwarding.

• Graphics Usage

  The new Graphics Usage feature allows you to identify the graphical references that exist in your system. For example, you can confirm where a Genie or symbol is used, or if a project contains unused graphics.

  To take advantage of this feature, see the new Used By section of the Libraries view in the Visualization activity (see Browse Libraries in Plant SCADA Studio).

• Graphics Editing Enhancements

  Graphics Builder now persists its window positions and the size of the "Go To Object" dialog. See Object Groups.

• Driver Classifications

  As part of an ongoing effort to set clear expectations and provide better support to our customers, we have introduced a classification system for our driver portfolio to communicate the level of ongoing maintenance and version updates that customers can reasonably expect. These classifications and status of each driver can be found online at https://gcsresource.aveva.com/PlantSCADA/Drivers/.

  In line with these classifications, we have limited the number of drivers included by default on the Plant SCADA installation media to a reduced set of ‘core’ drivers that have undergone recent updates, however all other drivers continue to be available for download from the Communication Drivers page at the AVEVA Knowledge and Support Center.

  It is recommended that you visit on a regular basis and subscribe to the forum so that you are alerted to any updates that occur.

  For more information, see Install Communication Drivers.
