Are there any operator interface software platforms that support high availability and role-based access control?

Yes. Several operator interface / HMI / SCADA platforms support both high availability (HA) and role-based access control (RBAC). Common examples include:

• AVEVA System Platform / InTouch

  • Supports redundancy/HA options
  • Has user/role-based security controls

• Siemens WinCC

  • Offers server redundancy and failover options
  • Supports user groups and permission-based access

• Rockwell FactoryTalk View / FactoryTalk Security

  • Supports redundant architectures in some deployments
  • Provides centralized security with roles and permissions

• Ignition by Inductive Automation

  • Supports redundant gateway architecture for HA
  • Uses users/roles for RBAC, including integration with external identity providers

• GE Digital iFIX / CIMPLICITY

  • Offers redundancy features
  • Includes user security and permissions

• Schneider Electric EcoStruxure/AVEVA-based HMI tools

  • Can be deployed with redundancy
  • Support authenticated user roles and access levels

If you want, I can also give you:

1. a comparison table of HA vs RBAC features, or
2. recommendations based on your environment, such as process plant, utilities, manufacturing, or remote operations.
