1.Core Functions

1. Multi-protocol Gateway & Multi-vendor Device Integration (Core Feature) No additional FBM Fieldbus Modules required for third-party field device connection. It supports mainstream industrial communication protocols: serial Modbus RTU, Ethernet Modbus TCP, OPC UA, EtherNet/IP and TSAA (for Triconex SIS safety system interconnection). It unifies inverters, third-party PLCs, transmitters and safety interlock systems into Foxboro DCS platform.
2. Local Distributed Process Control Calculation Equipped with independent full-function control engine to execute PID regulation, logic interlock, timing sequence and sequential control. It supports closed-loop regulation of flow, pressure and temperature with minimum 100ms control cycle, and runs process logic autonomously when disconnected from central control network.
3. Plant-wide Data Acquisition, Archiving & HMI Visualization Collect real-time parameters from third-party equipment and upload to DCS operator stations for monitoring display. It automatically archives historical data and trends, supporting up to 8,000 I/O data tags per single controller.
4. Global Alarm Detection & Sequence of Events (SOE) Recording Real-time monitoring of communication failures and process over-limit alarms, with microsecond-level SOE time-stamping for accident tracing. Multi-level alarm notifications are sent to central control consoles.
5. Redundant Fault-tolerant High-availability Operation Supports dual-module hot standby redundancy with dual backup for control calculation and communication links. Seamless switchover occurs upon single module or cable failure to ensure uninterrupted production control, complying with strict safety standards for chemical and power industries.
6. Online Driver Upgrade & Remote Maintenance Protocol drivers can be downloaded and updated online without power-off shutdown. Remote diagnosis, parameter download and firmware upgrade are available via DCS control network to minimize on-site downtime maintenance.
7. Industrial Cybersecurity Protection Certified to ISA EDSA industrial cybersecurity standards. OPC UA supports dual authentication via digital certificates and user passwords to isolate field equipment from upper central control network and prevent network intrusion risks.
8. Integrated Interconnection with SIS Safety Instrumented Systems Direct connection to Triconex triple modular redundant SIS systems via TSAA protocol to realize data exchange between DCS process control and safety interlock logic, building an integrated plant-wide management & control platform.

2. Main Industrial Applications

1. Large Refining & Petrochemical Plants Integrate variable frequency pumps, compressors, online analyzers and third-party PLCs; execute local closed-loop temperature & pressure control for reactors and distillation towers, and connect all equipment to Foxboro DCS central control system.
2. Thermal Power Plants & New Energy Power Stations Interface wind turbine inverters, desulfurization & denitrification PLCs, boiler transmitters and Triconex furnace safety SIS systems for centralized monitoring and interlock protection of unit load and flue gas parameters.
3. Water Treatment & Seawater Desalination Plants Integrate water pump inverters and online water quality analyzers, implement automatic constant pressure water supply and water quality adjustment, reducing DCS wiring and hardware investment.
4. Pharmaceutical & Fine Chemical Clean Process Workshops Execute multi-point temperature & pressure sequential control, convert protocols of third-party weighing and packaging equipment, and realize complete process data archiving to meet GMP requirements.
5. Long-distance Oil & Gas Pipelines and LNG Tank Terminals Field-mountable for remote valve chamber deployment, collect data from flowmeters and pressure transmitters over long distances. Redundant architecture guarantees uninterrupted control of oil & gas transportation.
6. Metallurgy & Cement Production Lines Connect drive inverters and cooling system PLCs, execute local kiln and rolling mill process logic to reduce computing load on central control servers.
7. DCS Retrofit & Upgrade for Legacy Factories Replaces outdated complex CP+FDSI hardware solutions with 50% smaller footprint and less wiring, compatible with both new and old equipment to cut renovation workload and capital cost.
