EMERSON 5X00481G06 is the core CPU processor module for the OCR1100 controller in Emerson Ovation Distributed Control System (DCS). Together with 5X00481G04 and 5X00226G04, it belongs to the hardware of the OCR1100 platform. It delivers high reliability, bumpless redundancy and high-performance real-time control capabilities for critical industrial scenarios such as power generation, water treatment and sewage treatment. It serves as the core component enabling Ovation DCS to achieve millisecond-level control and uninterrupted operation of mission-critical tasks.
Core Positioning & Functions
As the computing and scheduling core of the OCR1100 controller, it is responsible for executing control strategies including continuous PID control, logic control, sequence control and advanced control.It completes I/O acquisition, Sequence of Events (SOE) recording, alarm processing, engineering unit conversion and database management.It supports redundant architecture to realize bumpless automatic failover.It connects with local/remote Ovation I/O, WDPF I/O and virtual I/O of third-party devices.It stores application programs, point libraries, configuration and tuning parameters in non-volatile memory.

Key Technical Features
Bumpless Redundancy & High Availability
The primary and standby CPUs synchronize memory and status in real time. The watchdog circuit enables rapid failover upon fault occurrence, with no fluctuation in control output and no interruption to process operation. It supports full-link redundancy of power supply, network and I/O interfaces.
Real-Time Control Performance
5 independent control tasks with a minimum cycle of 10 ms; SOE resolution up to 1 ms, meeting the requirements of electrical fast switching and fault playback.
Open Compatibility & Expandability
Compatible with Ovation Version 3.5 and above, capable of replacing OCR400 with full functions retained. It supports local/remote I/O, and protocols including Modbus/TCP, DF‑1, Profibus, DeviceNet and FF, enabling connection with third-party PLCs and unit virtual I/O.
Safety & Compliance
Achilles Level 1 certification enhances industrial network anti-attack capability; fully compliant with IEC 61131‑3 programming standard for good engineering portability and maintainability.
Maintenance-Free Design
Fanless, wide temperature range and low power consumption design for long-term continuous operation. It supports on-line diagnosis, task cycle monitoring, custom alarm threshold and delayed alarm reporting.
Typical Application Scenarios
- Thermal power / nuclear power / hydropower / wind power / PV unit control
- Urban water supply, sewage treatment and water pump station automation
- Control of critical loops for industrial boilers, heat exchange stations and HVAC systems
- Key power and energy systems requiring high-reliability redundancy and SOE fast switching
FAQ
- What is the difference between 5X00481G06, G01 and G04?All three are OCR1100 CPU modules with identical core functions, performance, point capacity and control cycles. The differences lie mainly in hardware batch, production revision and minor interface configuration. They are compatible and interchangeable in the same system, matching Ovation system version 3.5 or above is recommended.
- Can this module directly replace OCR400?Yes. The OCR1100 platform hardware is backward compatible and can serve as a direct replacement for OCR400, enabling all new features in system versions that support OCR1100.
- Will redundant switching cause control disturbance?No. It is officially designed for bumpless failover. The primary and standby CPUs synchronize databases, parameters and output status in real time. The output can be tracked in the first cycle after switching without process impact.
- What is the maximum I/O capacity supported?Subject to the OCR1100 controller: maximum 128 local Ovation I/O modules; up to 16 remote I/O nodes. It also supports Q‑Line I/O and third-party virtual I/O (only one extended I/O type can be enabled at a time).
- What are the operating temperature and installation requirements?4×RJ45 version: 0–60 °C; 1×RJ45+3×SFP version: 0–50 °C; humidity 0–95% non-condensing. DIN rail mounting, recommended for installation in standard Ovation control cabinets with guaranteed ventilation and grounding.
- Is additional license required for advanced functions?Advanced control, simulation and virtual controller functions require additional software licenses; basic control, redundancy, SOE and data acquisition are supported by default via hardware.
