Honeywell TC-CCR013 ControlNet Redundant Communications Module

The TC-CCR013 serves as a high-performance ControlNet interface within the ControlLogix architecture, engineered specifically for mission-critical applications requiring physical media redundancy. Unlike standard single-channel modules, this dual-media interface ensures continuous data flow across redundant trunk cables (Trunk A and Trunk B). It facilitates high-speed, deterministic communication between controllers, I/O chassis, and human-machine interfaces (HMI) in complex industrial networks.

Detailed Engineering Specifications

Network Topology Constraints

Common Applications

• High-Availability Systems: Used in chemical processing, power generation, and wastewater treatment where network failure is not an option.

• Harsh Environments: Deployment in extreme temperature zones or corrosive areas using Plenum-rated FEP cabling.

• Extended Reach Networks: Utilizing repeaters and fiber optic bridges to span distances up to 10,000 meters.

Technical FAQ

What happens if Trunk A is disconnected?

The TC-CCR013 automatically switches to Trunk B without interrupting the process data. The module continuously monitors the health of both paths to ensure deterministic performance.

Can this module be used with fiber optics?

Yes, while the module natively uses BNC coax, it can interface with fiber optic segments through the use of ControlNet fiber repeaters to extend the total network distance to 10 km.
