ABB CI853-1

Description

Product Description

The ABB CI853-1 is a high-performance communication interface module for the ABB AC 800M controller platform, serving as a critical link for peer-to-peer controller communication. Specifically, this module implements the ABB MasterBus 300 industrial fieldbus protocol as a Communication Adapter (CA). Its primary function is to enable deterministic, high-speed data exchange between multiple AC 800M controllers and other compatible devices on a MasterBus 300 network, facilitating distributed control architectures. The ABB CI853-1 is engineered for reliability in demanding industrial environments, forming the communication backbone for synchronized multi-controller applications. For detailed technical specifications and configuration guides, please visit the official product page for the ABB CI853-1. The robust and deterministic nature of the ABB CI853-1 module is essential for building scalable and responsive distributed control systems within ABB’s automation ecosystem.

Product Parameters

• Product Type: MasterBus 300 Communication Adapter (CA) Module.

• Model: CI853-1.

• Protocol: Implements the ABB MasterBus 300 (MB300) protocol, a deterministic, token-passing fieldbus.

• Communication Speed: Operates at a high data transfer rate, typically 1.5 Mbit/s, ensuring fast and predictable data exchange.

• Connector: Uses a proprietary, high-density connector for the MasterBus 300 trunk cable.

• Topology: Supports a bus (trunkline) topology with drop cables to individual stations (controllers).

• Function: Acts as a CA station on the MB300 network, allowing the host AC 800M controller to send and receive process data and messages with other CAs and MasterBus 300 devices.

• Integration: Installs directly into a slot on the AC 800M controller’s baseplate (e.g., for PM861, PM864) and is configured via ABB’s Control Builder M engineering software.

• LED Indicators: Provides status LEDs for power, module status, and MasterBus 300 network activity (e.g., token possession, communication errors).

Advantages and Features

The key advantage of the ABB CI853-1 is its provision of a deterministic and high-performance communication channel specifically optimized for the AC 800M controller family. It enables tight synchronization and fast data sharing between controllers, which is crucial for applications where control logic is distributed across multiple CPUs. The MasterBus 300 protocol offers predictable, collision-free communication, making it suitable for time-critical control loops spread across a network. The module is fully integrated into the Control Builder M engineering environment, allowing for centralized configuration of network parameters and data exchanges. The ABB CI853-1 is known for its industrial ruggedness and reliability, supporting continuous operation in process-critical environments.

Application Cases in Various Fields

• Distributed Process Control: Connecting multiple AC 800M controllers managing different sections of a large continuous process plant (e.g., refining, chemical processing) to share setpoints, interlocks, and production data in real-time.

• Power Plant Automation: Enabling communication between separate controllers for boiler control, turbine control, and balance-of-plant systems within a MasterBus 300 network for coordinated plant operation.

• Large Machine/Line Control: Synchronizing several AC 800M controllers each responsible for a different zone or cell in a complex manufacturing line, such as in automotive body shops or paper machines.

• System Expansion: Facilitating the addition of new controller stations to an existing MasterBus 300 network without compromising the performance of the existing control system.

Comparison with Competing Products

The ABB CI853-1 operates in a specific niche within ABB’s ecosystem. Compared to open-standard Ethernet-based modules (like CI871 for Ethernet/IP), the CI853-1 uses a proprietary, deterministic protocol (MB300) which can offer more predictable performance for tightly synchronized tasks, though with less multi-vendor interoperability. Within ABB’s range, it differs from PROFIBUS modules (CI868) or Ethernet modules by providing a dedicated controller-to-controller backbone. Competing products from other vendors would be proprietary controller network modules, such as Siemens’ CP 443-1 for Industrial Ethernet or Schneider’s Modbus Plus adapters. The ABB CI853-1‘s primary strength is its optimized, native integration for creating high-performance distributed AC 800M systems.

Selection Suggestions and Precautions

1. System Architecture: The ABB CI853-1 is only relevant if you are designing or maintaining a system based on the ABB MasterBus 300 protocol. Verify this is your existing or intended network architecture.

2. Controller Compatibility: Ensure the module is compatible with your specific AC 800M processor and that you have a suitable free slot on the baseplate.

3. Network Planning: MasterBus 300 requires careful network planning, including correct termination resistors at both ends of the trunk, proper cable types, and adherence to maximum cable lengths and station counts.

4. Configuration: All network configuration, including station addresses and data exchange tables (Producer/Consumer configuration), is performed within Control Builder M. Expertise in this software and the MB300 concept is required.

5. Redundancy: If network communication redundancy is critical, explore the availability of redundant MasterBus 300 network options or consider system-level controller redundancy.

6. Legacy Consideration: MasterBus 300 is a well-established but older technology. For new projects, evaluate if open standard Ethernet-based solutions (with appropriate real-time
