Description

Key Applications

At a large combined-cycle power plant in Asia,the turbine control system(TCS)from a third-party vendor used PROFIBUS DP for I/O communication,while the main DCS was based on ABB’s Symphony platform.

To integrate TCS status signals(bearing vibration,speed,valve positions)into the central DCS for monitoring and alarm handling,engineers installed the ABB SINT4330C 3BSE020811R1 in the DCS I/O rack.The module was configured as a DP slave connected to the TCS’s PROFIBUS network.

Within hours of commissioning,all critical turbine parameters were visible in the DCS HMI,enabling operators to view integrated plant-wide data on a single screen.The SINT4330C ensured deterministic,low-latency communication with less than 10ms cycle time,meeting the plant’s operational requirements.

This deployment eliminated the need for hardwired analog/digital signals,reducing cabling costs and improving system flexibility.

Technical Principles&Innovation Highlights

1.Seamless System Integration

The SINT4330C allows ABB DCS systems to communicate with non-ABB devices using the widely adopted PROFIBUS DP standard—eliminating data silos and enabling unified control strategies.

2.High Availability with Redundancy

Supports redundant PROFIBUS networks(e.g.,via SINT4330C dual units),ensuring continuous communication even if one network segment fails—critical for safety and process continuity.

3.Plug-and-Play Configuration

Configured via ABB’s engineering tools(e.g.,Control Builder M),the module integrates easily into the DCS I/O structure.Device profiles(GSD files)can be imported for fast setup.

4.Real-Time Performance

Guarantees deterministic data exchange with cycle times suitable for process control(typically 1–50 ms),ensuring timely updates of field data.

5.Robust Industrial Design

Built for 24/7 operation in harsh environments with EMI resistance,wide temperature tolerance,and secure DIN-rail mounting.

Application Cases&Industry Value

Oil Refinery(Middle East):Used SINT4330C to connect ABB DCS with Siemens S7-400 PLCs controlling pump stations.Achieved full remote monitoring and reduced interface errors by 70%.

Water Treatment Plant(Europe):Integrated multiple wastewater lift stations using PROFIBUS-connected RTUs.The SINT4330C enabled centralized control without additional I/O cards or cabling.

Steel Mill(China):Connected rolling mill drives(ABB ACS800 series)to the DCS via PROFIBUS.Enabled real-time speed,torque,and fault status monitoring in the main control room.

These cases demonstrate how the SINT4330C reduces integration complexity,lowers engineering costs,and enhances operational visibility.

Installation,Maintenance&Support

Installation Steps:

Mount the SINT4330C on a 35mm DIN rail in an SDCS I/O rack.

Connect to the OCS backplane for power and internal communication.

Wire the PROFIBUS RS-485 interface using twisted-pair shielded cable.

Terminate both ends of the bus with 220Ωresistors.

Configure via Control Builder M using GSD files from connected devices.

Maintenance Tips:

Check LED status regularly(PWR,RUN,COM,ERR).

Inspect cable connections and shielding integrity.

Monitor bus error counters in the DCS diagnostics.

Replace if communication failures persist after troubleshooting.

Full-Cycle Support:

We offer technical documentation,configuration support,GSD file assistance,and retrofit planning for legacy ABB DCS systems using the SINT4330C.

Whether you’re integrating a new drive system or replacing a failed module,the ABB SINT4330C 3BSE020811R1 delivers reliable,standards-based communication for industrial automation.
