Product Overview

The 51403776-100 is a Local Control Network (LCN) processor or interface card designed to connect Honeywell Experion, TPS, or legacy servers to LCN-based control infrastructure.

This card bridges PC-based operator stations and distributed controllers on the LCN, enabling data acquisition, alarming, and supervisory control in TDC 3000 and TPS environments.

Key Features & Specifications

• LCN connectivity: Hardware connection to Local Control Network using coaxial cabling.
• Processor: Capable microprocessor and RAM for LCN protocol processing and data buffering.
• Memory: Typically 16 MW or higher supporting large node counts and complex data structures.
• Form factor: Half-length PCI or PCIe card for server/workstation integration.
• Time synchronization: GPS time-sync connector for coordinated timing across LCN nodes.
• Node addressing: Configurable LCN address with auto-discovery and conflict resolution.
• Compatibility: Compatible with GUS R110.1+ and legacy TDC 3000/TPS systems.

Typical Applications / Use Cases

LCN processor cards integrate modern PC servers with existing Honeywell distributed control systems.

• Connecting Experion/TPS servers to legacy LCN systems for data acquisition and operator interface without controller replacement.
• Enabling workstations to emulate Universal Stations on LCN, providing modern interfaces to aging infrastructure.
• Bridging communications during phased migrations where modern and legacy systems coexist.
• Supporting GPS-synchronized time coordination for sequence-of-events analysis.

Advantages / Why It Matters

• Investment protection: Upgrade servers while continuing to use installed LCN controllers.
• Improved performance: Newer generations provide higher capacity and memory than earlier versions.
• GPS time synchronization: Critical for precise event logging in regulated industries.
• Backward compatibility: Seamless legacy system integration minimizes engineering effort.
