Interfaces and Configuration

Network Interface: LCN coaxial cable interface (BNC connector, 75Ω impedance)

Backplane Interface: Standard TDC 3000 cabinet slot (compatible with 51400665-100 backplane)

Status Indicators: PWR (power), LCN ACT (network activity), FAULT (fault) LEDs

Installation Method: Hot-swappable (supports on-line replacement)

Compatibility: Directly replace the old LCN interface card, compatible with the entire series of TDC 3000 cabinets Core function

LCN Network Access: Provides LCN network interfaces for older processors such as HPK2/HMPU, enabling communication and interconnection between the controller and the TDC 3000 system, and completing data acquisition, command issuance, and status reporting.

Data Forwarding and Protocol Conversion: Performs data format conversion and protocol adaptation between the internal bus of the processor and the LCN network, ensuring seamless data interaction between nodes of different architectures.

Network Status Monitoring: Monitors the communication status of the LCN network, data transmission quality, and link failures in real time. When an anomaly occurs, it triggers system alarms to facilitate rapid identification of network issues.

Redundant Communication Support: Supports dual LCN network redundancy configuration. In the event of a single network failure, it automatically switches, with the switching time being less than 50 ms, ensuring uninterrupted communication of critical control nodes.

Compatibility with Old Systems: Specifically adapted for early non-integrated processor nodes, addressing communication compatibility issues in the mixed architecture of new and old systems, and supporting smooth upgrade and expansion of the old system. Applicable scenarios

System: Honeywell TDC 3000, TPS, Experion PKS (compatible with older nodes)

Processor nodes: Non-integrated processor cabinets such as HPK2-2, HPK2-3, HMPU, etc.

Industry: Petrochemicals, thermal power, nuclear power, metallurgy, cement, glass, pharmaceuticals

Application: Old system renovation, access to older processor networks, LCN network expansion, replacement of communication fault cards, mixed networking of new and old systems
