Automation and control systems {Distributed Control Systems (DCS)
Overview
Yokogawa’s DCS solutions provide automation and control platforms for large-scale industrial plants (oil & gas, petrochemical, power, water/wastewater, chemicals, etc.). Their flagship system is the CENTUM VP series (part of the OpreX Control and Safety System family). Yokogawa+2Automation.com+2
Key points:
A DCS (Distributed Control System) decentralises control: controllers and I/O nodes are distributed throughout the plant, rather than all control being in one central unit. Yokogawa+1
Yokogawa introduced the original CENTUM DCS in 1975 and today it is in its 10th generation. Control Design+1
Their system supports continuous operations, high availability, and integration of control, safety and information layers. Yokogawa+1
Key Features & Benefits
Here are some of the standout features of Yokogawa’s DCS solutions:
Separation of operator interface and controllers: If the HMI (Human‐Machine Interface) fails, the controller continues managing the process, enhancing reliability.
Decentralised installation of I/O and controllers: Field nodes can be placed closer to process equipment, reducing wiring and improving maintainability.
High system availability and fault tolerance: Controllers and partitions can fail without taking down the entire system. Yokogawa+1
Backward compatibility & migration support: Yokogawa emphasizes that upgrades are designed to preserve investment and minimise downtime.
Standards compliance and cyber-security: Supports ISA/IEC standards like ISA-18.2 (alarm management), ISA-95 (enterprise control integration), ISA-99/IEC 62443 (cybersecurity) among others.
Typical Solution Architecture
The architecture of a Yokogawa DCS system typically involves:
Field devices and I/O modules distributed across the plant.
Control stations/controllers (often dual redundant) performing real-time control.
A high-speed control network (for example, Yokogawa’s Vnet/IP) linking controllers, I/O and HMIs.
Operator stations/HMIs for monitoring & control.
Integration with enterprise systems, historical databases, batch systems, safety systems.
Tools for engineering, diagnostics and maintenance.
Product & System Offerings
Some of the relevant offerings include:
CENTUM VP Series: Yokogawa’s current flagship DCS product line. Yokogawa+1
Migration solutions for upgrading older DCS systems (including earlier CENTUM variants) to the newer platform, with minimal downtime.
Related modules: alarming/condition monitoring, field instrument management, batch control, safety instrumented systems (SIS) integrated with the DCS.

Safety Systems {Safety Instrumented systems (SIS)
A Safety Instrumented System (SIS) is a dedicated system whose role is to detect abnormal conditions, intervene, and bring the process to a safe state. In other words, while the process control system (DCS / PLC) handles normal operations, the SIS acts as a protection layer for humans, assets and the environment.
Why it matters:
For industrial plants in oil & gas, petrochemical, power, terminals, etc., risk of major incidents (fire, explosion, overpressure, toxic release) is real. The SIS is a key layer of protection.
Regulatory compliance: Many jurisdictions require SIL-rated safety systems and documented lifecycle management.
Integration benefits: A well-designed SIS can integrate with the control system (DCS) but still maintain independence for safety. Yokogawa emphasises this balance.
Typical Applications
Yokogawa’s SIS solutions are applied in:
Emergency Shutdown (ESD) Systems: automatically shut down plant/process when predefined unsafe condition occurs.
Fire & Gas (F&G) Systems: detection and mitigation of fire, gas leak scenarios. Yokogawa+1
Burner Management Systems (BMS): for incinerators, boilers, furnaces — ensuring safe start/stop and shut-off in unsafe conditions.
High Integrity Pressure Protection Systems (HIPPS): relevant in pipeline, subsea, chemical plants to prevent overpressure incidents.
Integration with larger “Integrated Control & Safety Systems” (ICSS) architectures: SIS + DCS + instrumentation in unified environment.

Internet of Things (IoT) – enabled monitoring
What this means & Why it matters
“IoT/IIoT-enabled monitoring” refers to remote, networked sensing and analytics of assets/equipment, often via wireless sensors + gateways + cloud or local servers.
For Yokogawa, the goal is to move from reactive or scheduled maintenance toward condition-based monitoring and predictive maintenance, improving uptime, reducing unplanned shutdowns, and optimising maintenance cost.
With distributed facilities (plants, remote sites, large footprint), traditional wired measurements are often impractical. Wireless/IoT solutions help cover wide areas, harsh environments, and gather data for analytics.
This kind of monitoring is of growing importance in African markets (mining, oil & gas, utilities) where remote assets and wide-area operations are common.
Typical Use-Cases & Benefits
Remote asset health monitoring: instead of manual rounds, sensors continuously monitor equipment condition and send alerts early when signs of degradation appear. (E.g., steam traps, pumps, rotating equipment) Yokogawa+1
Wide‐distributed facility monitoring: For example, pipeline pressure monitoring across remote sites or remote water supply monitoring; remote equipment spread over large geography.
Condition-based maintenance (CBM) and predictive maintenance: By trending sensor data (vibration, temperature) and applying analytics, you can catch problems before failure.
Energy/efficiency optimisation: Monitoring steam traps, leaks, etc., helps reduce waste (e.g., GHG emissions) and improves operational cost.
Data-driven decision-making: By capturing more data and making it visible to maintenance, operations, management, you improve decision making (what to service, when).
