Interfaces and Configuration

Installation: Slot of C300 controller chassis, supports hot swapping

Panel Indicators: PWR, COM A/B, ACT, FAULT, REDY, etc. LED

Configuration: Set link address, baud rate, redundancy mode through Experion PKS/TPS software

Redundancy: Supports 1:1 link redundancy, fault switching < 50 ms

Core Functions

High-speed I/O Data Exchange: C300 reads and writes with remote I/O (such as FTA, I/O subrack) in real time

Link Redundancy Management: Both HIO links work simultaneously, automatic seamless switching occurs when a single link fails

I/O Subrack Expansion: One card can carry multiple I/O subracks, supports distributed I/O architecture

Diagnosis and Alarm: Report faults such as link interruption, CRC error, node offline, etc. to the system

Time Synchronization: Support full network time synchronization to ensure consistent SOE event timing Application scenario

System: Honeywell Experion PKS, TPS, TDC3000 (C300 controller platform)

Industry: Petrochemicals, power, metallurgy, papermaking, pharmaceuticals, etc. (process industries)

Typical configuration: C300 controller + 51401642‑150 + remote I/O subrack (such as 51401643‑150)
