Product Detailed Description
The Allen-Bradley Central Control Module, specifically the 1756-CCM (Central Compact Module), is a key component in Rockwell Automation’s ControlLogix family of chassis-based systems. It serves as a compact communication and control interface designed for distributed control architectures. This module enables seamless integration between local I/O chassis and remote CompactLogix controllers, supporting EtherNet/IP and DeviceNet networks for high-speed data exchange. Built for industrial environments, the 1756-CCM facilitates centralized management of I/O signals, reducing wiring complexity and enhancing system scalability. It is typically used in conjunction with a 1756 chassis and is programmed using Studio 5000 Logix Designer software, allowing for advanced diagnostics and configuration.

Product Advantages
The 1756-CCM offers several key benefits that make it a preferred choice for modern automation systems:
- Scalability and Flexibility: Easily expands from small to large systems with support for multiple chassis and up to 500 nodes on EtherNet/IP networks, allowing seamless growth without major redesigns.
- High-Speed Communication: Dual EtherNet/IP ports provide redundant connectivity and deterministic performance, reducing latency in real-time control applications.
- Integrated Diagnostics: Built-in status LEDs and software tools enable quick troubleshooting, minimizing downtime and maintenance costs.
- Robust Design: Operates in harsh environments (IP20 rating, vibration-resistant up to 5g), with options for hazardous locations, ensuring reliability in manufacturing floors or outdoor installations.
- Cost Efficiency: Reduces wiring and panel space by centralizing control, potentially lowering installation costs by 20-30% compared to traditional distributed I/O setups.
- Seamless Integration: Fully compatible with Logix5000 controllers and FactoryTalk software, simplifying programming and data analytics for predictive maintenance.
Overall, it enhances productivity by combining centralized control with distributed intelligence.
Precautions (Attention Matters)
To ensure safe and optimal operation of the 1756-CCM, observe the following precautions:
- Installation: Install in a grounded chassis with proper power supply (24V DC nominal). Avoid installing in slots adjacent to high-heat modules without adequate ventilation.
- Environmental: Use only in pollution degree 2 environments (non-conductive pollution). Protect from direct sunlight, corrosive gases, or excessive vibration (>5g). For hazardous locations, adhere to ATEX/IECEx guidelines and use approved enclosures.
- Wiring: Use shielded twisted-pair cables for EtherNet/IP connections to prevent EMI. Do not exceed 100m cable length without repeaters. Verify field wiring polarity before powering on to avoid damage.
- Power and Safety: Disconnect power before inserting/removing the module. The module is not hot-swappable in live systems. Replace lithium battery (if applicable for clock backup) every 5 years.
- Software: Update firmware using ControlFLASH tool only on isolated networks to prevent cyber vulnerabilities. Follow Rockwell’s cybersecurity guidelines, including network segmentation.
- Maintenance: Periodically inspect for dust accumulation and connector corrosion. Do not operate outside specified temperature/humidity ranges, as it may void warranty.
Failure to follow these may result in equipment damage, safety hazards, or invalidation of certifications.
Product Applications
The 1756-CCM is versatile for various industrial scenarios, including:
- Manufacturing Automation: Centralizes control in assembly lines for automotive or electronics production, managing sensors, actuators, and conveyors with real-time EtherNet/IP synchronization.
- Process Control: Used in oil & gas or chemical plants for remote I/O monitoring, integrating with SCADA systems for pressure, flow, and temperature regulation.
- Water/Wastewater Treatment: Supports distributed pump stations and valve controls, enabling efficient resource management over large sites.
- Material Handling: Enhances warehouse automation with coordinated motion control for sorters, lifts, and AGVs.
- Energy Management: Applies in power generation for substation monitoring, providing reliable data acquisition in harsh outdoor conditions.
- Food & Beverage: Facilitates hygienic processing lines with IP69K-rated variants for washdown environments, ensuring compliance with FDA standards.
Its modular design makes it ideal for any setup requiring centralized oversight of remote assets.
