Main Functions

1. Protocol conversion gateway: Translate ABB proprietary INFI-NET bus signals to universal fieldbus signals for third-party PLC, HMI, SCADA connection
2. Real-time data forwarding: Transmit field measurement values, equipment status, fault alarm data between DCS and upper monitoring systems
3. Remote control channel: Receive control commands from external fieldbus master to adjust DCS loop output
4. Bus fault diagnosis: Automatic detection of bus disconnection, short circuit, signal attenuation with local alarm and system event recording

Product Advantages

1. Native matching with ABB INFI 90 DCS system, stable and seamless communication without additional conversion equipment
2. Multi-protocol compatibility, flexible access to different brand automation devices and industrial upper computer monitoring platforms
3. Hot-swap design reduces system maintenance downtime for continuous production factories
4. Electrical isolation between internal and external buses effectively avoids grid noise interference causing communication failure
5. Compact rack-mounted design saves cabinet layout space, integrated status indicators for quick troubleshooting
