Frequently Asked Questions
Ovation PLCs extend the Ovation Automation Platform into high-speed, and equipment-level applications such as skids, auxiliaries, and packaged systems—while maintaining integration with plantwide Ovation operations, monitoring, and optimization.
Ovation PLCs are designed to exchange data seamlessly with the Ovation Automation Platform using standard industrial protocols and engineered integration, providing operators with unified visibility and coordinated control across both process and equipment-level assets.
PLCs are typically used for high-speed, equipment-level control - such as skid-based systems, balance-of-plant equipment, and auxiliary processes - while Ovation controllers manage continuous process control, and plantwide high speed coordinated control.
Yes. Ovation PLCs are designed to support the performance, reliability, and lifecycle requirements of power plants BOP, renewable energy systems, water treatment facilities, and other critical infrastructure environments.
Ovation PLCs are configured using PAC Machine Edition, a unified development environment that supports IEC 61131 programming languages and provides tools for configuration, diagnostics, and lifecycle support.
With modular architectures, flexible I/O options, and open communication standards, Ovation PLCs enable incremental expansion and modernization—allowing facilities to upgrade or extend control capabilities without requiring full system replacement.
