Honeywell TC-CCR014 Redundant Network Interface Card

Resilient Network Architecture for Critical Data Exchange

The Honeywell TC-CCR014 redundant network interface card provides two independent communication paths. This card ensures uninterrupted data flow between controllers and supervisory systems. It automatically detects network failures and initiates seamless failover. You gain enhanced network uptime without operator intervention. This card integrates perfectly with Honeywell’s Experion PKS and TDC 3000 platforms.

Communication Protocols and Network Management

This interface card supports standard TCP/IP and UDP protocols for flexible integration. It also handles Honeywell’s proprietary data exchange formats efficiently. The card maintains two active connections simultaneously for redundancy. It continuously monitors each link for errors and signal integrity. The card also manages traffic prioritization for critical control messages. This management ensures timely delivery of essential process data.

Redundancy Logic and Failover Mechanism

The card uses a heartbeat protocol to verify link health continuously. It sends periodic test messages across both network paths. Upon detecting a primary link failure, the card activates the standby path instantly. This transition occurs without losing any data packets. The card also supports manual switchover for maintenance purposes. Additionally, it logs all network events for troubleshooting and analysis.

Traffic Management and Data Buffering

The TC-CCR014 incorporates a 128 KB packet buffer for each network port. This buffer absorbs traffic bursts and prevents packet loss. It also facilitates smooth data flow during network congestion. The card implements quality of service policies for traffic prioritization. It gives highest priority to time-critical control messages. This prioritization ensures consistent loop response times. The card also filters unnecessary broadcast frames effectively.

Physical Dimensions and Connectivity Features

This interface card measures 28.5 cm in height and 17.8 cm in width. Its depth is 5.5 cm for standard rack installation. The device weighs approximately 1.0 kilograms. It provides two RJ-45 Ethernet connectors on the front panel. These connectors support both copper and fiber media via transceivers. The card also includes diagnostic LEDs for each network port. These LEDs display link speed, activity, and redundancy status.

Installation, Configuration, and Integration

You can install the TC-CCR014 into any TDC 3000 rack slot. Configuration involves assigning unique IP addresses to both ports. Software then sets the redundancy parameters and timeout thresholds. The card auto-negotiates speed and duplex with connected switches. It also supports VLAN tagging for network segmentation. Routine monitoring includes checking diagnostic LEDs and system logs.
