The 1C31166G02 is a dedicated serial link controller module exclusively designed for Emerson Ovation Distributed Control System (DCS). Its core function is to serve as a highly reliable, high-performance communication bridge between DCS controllers and a wide range of serial devices (such as PLCs, RTUs, remote instruments, etc.). Through multi-protocol conversion and data interaction, it ensures the real-time transmission of monitoring, control, and regulatory commands in industrial automation scenarios. Ideal for complex industrial environments including power generation, water treatment, and oil & petrochemical sectors, it stands as one of the key components enabling distributed device interconnection and expansion within the Ovation system.
Positioning & Core Functions
System CompatibilityExclusively engineered for the Ovation DCS, the module seamlessly integrates with the Ovation I/A Series backplane bus, enabling high-speed data synchronization with system controllers and ensuring bidirectional, real-time transmission of control commands and field data.
Multi-Protocol CommunicationIt natively supports mainstream industrial serial protocols including Modbus RTU/ASCII, DNP3, and PROFIBUS DP. This broad protocol compatibility allows interoperability with serial devices from different manufacturers, significantly lowering system integration complexity.
Dual-Port ConfigurationEquipped with 1 RS-232 port and 1 RS-485 port: the RS-232 port supports a maximum transmission rate of 115 kbps, ideal for short-distance point-to-point communication; the RS-485 port supports multi-point bus topology, catering to the requirements of long-distance, multi-node serial network expansion.
Data Conversion & RoutingThe module is responsible for converting control commands from DCS controllers into target serial protocol formats. Meanwhile, it receives field device data, standardizes the data, and uploads it to the controllers—ensuring data consistency and validity across different devices and protocols.
Diagnostics & MonitoringBuilt-in comprehensive communication status diagnostic functions enable real-time monitoring of port connection status, data transmission error rates, and protocol parsing status. It supports alarm triggering and fault localization via the Ovation® system Human-Machine Interface (HMI), minimizing system downtime.
Key Technical Specifications
Product Advantages
High CompatibilityBoasting multi-protocol support and dual-port design, the module is compatible with the vast majority of industrial serial devices. It eliminates the need for additional protocol conversion gateways, thereby reducing system costs and complexity.
High ReliabilityFeaturing an industrial-grade hardware design, its electromagnetic interference (EMI) resistance and anti-vibration performance comply with the IEC 61010-1 standard, making it well-suited for harsh industrial environments such as those in the power and chemical sectors.
Flexible ExpandabilityWith a modular design and hot-swappable functionality, the number of modules can be flexibly increased or decreased based on the quantity of on-site serial devices, meeting the requirements of system capacity expansion.
Easy MaintainabilityIntegrated with diagnostic functions, the module works in conjunction with Ovation system configuration software to enable quick configuration of communication parameters, protocol parameters, and diagnostic thresholds, simplifying commissioning and maintenance procedures.
Typical Applications & Industry Use Cases
The 1C31166G02 combination of versatility, reliability, and ruggedness makes it suitable for a wide range of industrial applications across key sectors:
Power IndustryIn thermal, hydropower, and nuclear power plants, the module connects serial devices including PLCs, intelligent instruments (e.g., temperature/pressure transmitters), excitation systems, and governors. It enables the DCS to realize centralized monitoring of auxiliary systems such as coal handling, water treatment, and desulfurization.
Water Treatment IndustryIn water supply plants and wastewater treatment plants, it connects remote terminal units (RTUs), water pump controllers, and water quality analyzers via the RS-485 bus, facilitating data acquisition and remote control of distributed stations.
Oil & Petrochemical IndustryIn oil refining and chemical processing units, the module interfaces with serial devices of the field safety instrumented systems (SIS), motor protection controllers, and valve positioners. It ensures the coordinated operation of process control and safety interlocking systems.
Industrial Automation UpgradesIn legacy system retrofitting projects, it serves as an interconnection node between the Ovation DCS and legacy serial devices. This protects existing equipment investments and enables a smooth transition between old and new systems.
