ABB CI522A 3BSE018283R1

Description

Product Description

The ABB CI522A 3BSE018283R1 is a high-performance, single-channel communication interface module for the ABB S800 I/O family. This module, commonly referred to as the CI522A, serves as a critical link, enabling direct and efficient serial data exchange between a master controller (like an AC 800M PLC) and field devices or subsystems using the RS-232C/V.24 communication standard. Integrating the 3BSE018283R1 CI522A into an S800 station provides a compact and reliable solution for point-to-point serial connections, essential for interfacing with peripherals such as barcode readers, weight scales, printers, or legacy PLCs. For engineers needing a robust serial port directly in the I/O rack, the ABB CI522A offers a streamlined and configurable interface.

Product Parameters and Specifications

• Product Type: Single-Channel Serial Communication Interface (RS-232C/V.24)

• Communication Standard: EIA RS-232C, CCITT V.24.

• Electrical Interface: Supports data rates up to 19.2 kbps, with configurable parameters for data bits, stop bits, and parity.

• Connector: Features a front-mounted 9-pin D-sub female connector (DCE pinout).

• Protocol Support: Supports transparent (character-based) communication, as well as protocol-specific drivers (e.g., for certain ABB drives or MODBUS RTU slave/master operation) depending on controller configuration.

• Galvanic Isolation: Provides isolation between the serial port and the internal S800 I/O bus for enhanced noise immunity.

• Configuration: Configured via the engineering tool (e.g., ABB Control Builder) for the connected master controller, setting baud rate, format, and operational mode.

• Compatibility: Designed for use in ABB S800 I/O stations, connecting to controllers like the AC 800M, AC 700, or Compact Product Suite.

Advantages and Features

1. Integrated Serial Connectivity: The ABB CI522A 3BSE018283R1 brings a standard serial port directly into the industrial I/O rack, eliminating the need for external serial converters or communication cards in the controller, simplifying cabinet layout and wiring.

2. High Noise Immunity: The built-in galvanic isolation protects the sensitive controller and I/O bus from electrical disturbances, surges, and ground loop issues commonly encountered on serial lines in industrial settings.

3. Flexible Protocol Handling: Its ability to operate in transparent mode or with specific protocol drivers provides versatility for connecting to both simple character-based devices and more complex, protocol-driven equipment.

4. Compact and Efficient: As a single-slot S800 module, it saves space and centralizes communication interfaces alongside other I/O points, improving organization and maintenance access.

5. Seamless System Integration: When used with an ABB controller, the CI522A is configured within the same engineering environment as the rest of the application, providing a unified view of data exchange and simplified diagnostics.

Application Cases in Various Fields

• Packaging and Labeling: Connects to barcode scanners or vision systems on a production line to read codes and send product data directly to the PLC for tracking and control decisions.

• Batch Weighing: Interfaces with precision weighing scales in pharmaceutical or food & beverage applications to receive weight data for ingredient dispensing and recipe control.

• Legacy System Integration: Provides a communication path to older machinery or devices (e.g., certain CNC machines, displays) that only offer an RS-232 port for data logging or start/stop commands.

• Data Logging and Reporting: Connects to local printers or serial terminal displays for generating hard-copy production reports or showing machine status.

Comparison with Competing Products

• vs. External USB/Serial Converters: While inexpensive, external converters are not industrially hardened, lack isolation, and introduce a point of failure (PC driver dependency, power supply). The 3BSE018283R1 is a rugged, integrated component with guaranteed performance and direct PLC driver support.

• vs. Controller-Embedded Serial Ports: Many PLC CPUs have built-in serial ports. Using the ABB CI522A offloads communication processing, frees up the controller’s central resources, and allows placement of the serial connection closer to the field device, reducing cable runs.

• vs. Multi-port Serial Communication Modules: Modules offering 2 or 4 RS-232 ports provide higher density. The single-channel CI522A is a cost-optimized solution for applications requiring only one point-to-point link, avoiding the expense of unused ports.

Selection Suggestions and Precautions

1. Verify Required Protocol: Confirm the communication mode required by your field device (e.g., simple ASCII string, MODBUS RTU). Ensure the CI522A and the connected ABB controller support the necessary protocol driver or transparent mode configuration.

2. Cable Specification: Use a high-quality, shielded cable with the correct pinout (DCE). The cable length should be kept as short as possible, ideally under 15 meters, to ensure reliable data transmission at higher baud rates.

3. Configuration Consistency: The communication parameters (baud rate, data bits, parity, stop bits) configured in the Control Builder project for the CI522A must exactly match the settings on the connected field device.

4. Grounding and Shielding: Properly terminate the cable shield at the field device end only to prevent ground loops, leveraging the module’s internal isolation for protection.

5. Diagnostics: Utilize the status LEDs on the front of the ABB 3BSE018283R1 CI522A module and the diagnostic tools in the engineering software to troubleshoot connection or data transfer issues.
