A modular O-PAS controll system with software-based redundancy, sub-cycle failover, and defense-in-depth cybersecurity, assembled from interchangable components you can replace minimal downtime
Built with
Built for high availability, open standards, and a lower install and total cost of ownership than proprietary DCS lock-in.
Default vendor passwords, unique credentials set at commissioning.
Software-based redundancy keeps control available through device failure and maintenance.
Performance headroom for advanced control, high-speed data, and analytics workloads.
O-PAS reference architecture, mix, replace, and upgrade components without vendor lock-in.
O-PAS modular layers connect system management, supervisory compute, real-time control, I/O services, and hazardous-area devices over open standards.
Supervisory workloads, analytics, and Fusion management.
Real-time CODESYS runtimes in containers on industrial PCs (ASRock)
Phoenix Contact Axioline F presenting field signals as OPC UA
R. Stahl Series 9442 for hazardous-area field devices
IEC 61131-3 on real-time Ubuntu with container isolation
OCF over OPC UA ties compute, I/O, and supervisory layers
Scale DCN, I/O, and ACP without rip-and-replace
CPLANE Fusion for deployment, health monitoring, & lifecycle updates
Segmented networks, zero-trust device access, certificate management
Layered controls from network edge to device identity, aligned with IEC 62443 and industrial best practice.
Perimeter and zone firewalls control north-south and east-west traffic between control layers.
Device and user access verified continuously, no implicit trust on the control network.
PKI-backed device identity and encrypted channels across OPC UA and management planes.
Role-based access tied to enterprise identity for operators, engineers, and admins.
Host protection on compute nodes with policies suited to industrial uptime requirements.
Isolated VLANs for control, I/O, management, and enterprise traffic paths.
Each layer uses proven hardware and software from partners you can source and support independently.
