Programmable via Emerson Control Builder using IEC 61131-3 standard languages (FBD, ST, SFC). Reduce commissioning time with pre-tested function blocks and comprehensive diagnostics.

Industry Applications & Problem Solving

✓ Chemical & Petrochemical Manufacturing
Manage complex batch reactors, distillation columns, and blending operations requiring precise temperature, pressure, and flow control. The OCC100's deterministic performance maintains product quality while the redundant architecture prevents costly batch losses during equipment failures.

✓ Oil & Gas Production Facilities
Control offshore platforms, wellhead automation, and pipeline monitoring systems in harsh environments. IEC 62443 cybersecurity protects remote assets from unauthorized access while HART integration enables predictive maintenance of field instruments.

✓ Power Generation Plants
Orchestrate boiler management, turbine governors, emissions monitoring, and auxiliary systems with millisecond precision. SIL 2 capability supports safety instrumented functions while OPC UA connectivity feeds real-time data to plant historians and optimization systems.

✓ Water & Wastewater Treatment
Optimize filtration, chemical dosing, UV disinfection, and SCADA integration across municipal facilities. The controller's 32K I/O capacity consolidates multiple treatment trains into a single control platform, reducing hardware costs and simplifying operator training.

✓ Pharmaceutical Manufacturing
Ensure FDA 21 CFR Part 11 compliance with audit logging, electronic signatures, and secure data integrity. Control cleanroom HVAC, fermentation vessels, and CIP/SIP systems while maintaining full batch traceability.

Technical Parameters & Selection Guide

Selection Criteria: Choose the OCC100 when your application requires more than 8,000 I/O points, demands deterministic control performance, or operates in regulated industries requiring cybersecurity certification. For smaller systems (under 8K I/O), consider the OCC050 model. For ultra-high availability applications, deploy in 1:1 redundant pairs.

Advanced Integration Features

Industrial IoT Connectivity: The OCC100's OPC UA server enables secure data exchange with cloud platforms, edge analytics systems, and mobile HMI applications. Publish real-time process data to AWS IoT, Azure Industrial IoT, or on-premises historians without compromising control network security.

Predictive Maintenance Integration: HART protocol support allows the controller to collect diagnostic data from smart field devices. Monitor valve travel deviations, transmitter drift, and loop health metrics to schedule maintenance before failures occur—reducing unplanned downtime by up to 35%.

Custom Function Block Development: Extend controller capabilities with proprietary control algorithms using Emerson's SDK. Implement advanced process control (APC), model predictive control (MPC), or custom safety logic tailored to your specific application requirements.

Frequently Asked Questions

Can the OCC100 controller integrate with our existing Ovation V3.5 system?
Yes, the OCC100 maintains full backward compatibility with Ovation V3.5 and later releases. You can deploy it alongside legacy controllers in hybrid configurations, enabling phased migration without system-wide replacement. Control Builder automatically manages version differences during engineering.

What redundancy architectures does this DCS CPU support?
The controller supports both N+1 (shared standby) and 1:1 (dedicated backup) redundancy topologies. Automatic failover occurs in less than 50 milliseconds with bumpless transfer, ensuring continuous process control during maintenance activities or component failures. Redundant pairs synchronize via dedicated Ethernet links.

How do I connect third-party PLCs and SCADA systems to the OCC100?
The built-in OPC UA server and Modbus TCP/IP client/server functionality enable seamless integration with virtually any industrial device. Configure data mappings through Control Builder's graphical interface—no custom programming required. The controller can simultaneously serve multiple OPC UA clients while polling Modbus slaves.

Which programming languages work with this automation controller?
The OCC100 supports all five IEC 61131-3 languages through Emerson Control Builder: Function Block Diagram (FBD), Structured Text (ST), Sequential Function Chart (SFC), Ladder Diagram (LD), and Instruction List (IL). Most users prefer FBD for continuous control and SFC for batch sequencing.

What cybersecurity measures protect the controller from network attacks?
The OCC100 implements defense-in-depth security aligned with IEC 62443 standards: secure boot verification prevents unauthorized firmware, AES-256 encrypted Ethernet communications protect data in transit, role-based access control limits user privileges, comprehensive audit logging tracks all configuration changes, and automatic security patch management keeps the system current.

Does the controller require special cooling or environmental controls?
No forced-air cooling is required. The OCC100 operates reliably in ambient temperatures from 0°C to 60°C (32°F to 140°F) with natural convection cooling. For installations in extreme environments, mount the controller in a climate-controlled cabinet or use the optional conformal coating for humidity and corrosion resistance.
