Honeywell TC-CCN013 Redundant Controller

Fault-Tolerant Architecture for Continuous Process Management

The Honeywell TC-CCN013 redundant controller delivers uninterrupted control for critical industrial processes. This controller operates as part of a dual-redundant pair for automatic failover. It eliminates single points of failure in your control system architecture. You gain enhanced system availability and operational reliability. This controller integrates smoothly with Honeywell’s Experion PKS and TDC 3000 environments.

Core Processing Capabilities and Memory Architecture

This module features a powerful 32-bit microprocessor for rapid loop execution. It provides ample memory for application programs and system databases. The controller supports online configuration changes without interrupting process control. Its advanced diagnostics continuously monitor both the controller and its peer. These diagnostics ensure the redundant pair remains synchronized at all times.

Redundancy Management and Data Synchronization

The controller actively synchronizes its database with the standby unit. It transfers all process data and setpoints continuously. This synchronization ensures the standby unit remains fully current. The module automatically initiates a failover upon detecting a hardware fault. This failover occurs seamlessly without process disruption. The controller also logs all events and alarms for audit trails. These logs provide valuable data for root cause analysis.

Energy Storage and Data Retention Capabilities

The TC-CCN013 includes a lithium coin cell battery for memory retention. This battery preserves critical data during power outages. It maintains the application program and configuration settings. The battery also sustains real-time clock operation. Its typical service life extends to five years. You can replace the battery online without system shutdown. This online replacement maintains system integrity and availability.

Physical Dimensions and Connectivity Options

The module measures 28.5 cm in height and 17.8 cm in width. Its depth is 5.5 cm for standard rack compatibility. The device weighs approximately 1.2 kilograms. It provides dual RS-232 ports for local communication. One RS-485 port supports Modbus connectivity to external devices. The controller also connects to a network via an Ethernet module. This connectivity enables seamless data exchange with higher-level systems.

Installation and Maintenance Strategy

You can install this controller in any TDC 3000 rack slot. Proper installation requires matching it with an identical unit. This pairing creates the redundant controller pair. The module supports online firmware updates for security patches. These updates do not affect the current process operation. Routine maintenance involves periodic battery checks and replacements. The controller’s diagnostic LEDs provide immediate status feedback.
