Product Description

The ABB SDCS-COM-81 is a specialized Printed Circuit Board (PCB) that serves to extend the communication and I/O capabilities of the main control board (SDCS-CON) within modern ABB DC drive converters like the DCS800.

It essentially acts as a communication hub and expansion slot aggregator. It provides:

• Fieldbus Connectivity: It often houses the connections and buffering for fieldbus adapter modules (e.g., Profibus, DeviceNet, Modbus) necessary for integrating the drive into plant-wide automation networks.

• Auxiliary I/O: It may provide additional digital or analog I/O points that expand beyond the capabilities of the main control board.

• System Interface: It manages the communication flow between the add-on modules and the main control processor.

The “81” indicates its specific function and design within the DCS800 control architecture.

Product Parameters

Product Advantages

• Network Flexibility: Crucial for allowing the DCS800 drive to integrate seamlessly into virtually any industrial automation network (via plug-in modules).

• I/O Scalability: Provides the ability to easily expand the drive’s I/O capacity to handle complex applications without needing a separate external PLC for simple signals.

• Modular Design: Allows users to select and install only the necessary communication and I/O modules, optimizing cost and complexity.

• High-Speed Communication: Designed to facilitate fast and reliable data exchange between the drive’s control system and the host controller.

Precautions

• Fieldbus Module Requirement: The SDCS-COM-81 itself only provides the infrastructure; a separate, specific Fieldbus Adapter Module (e.g., RDCO) must be plugged into it for network communication (like PROFINET or Ethernet/IP) to function.

• ESD Sensitivity: As a critical PCB, it must be handled only with proper Electrostatic Discharge (ESD) protection to avoid damage.

• Configuration: Proper drive parameter configuration (mapping of I/O and communication registers) is required within the DCS800 control panel software to activate and utilize the functions provided by the SDCS-COM-81.

• Compatibility: Ensure that any modules plugged into the SDCS-COM-81 are compatible with both the SDCS-COM-81 and the main SDCS-CON-8 drive control board.

Product Applications

The SDCS-COM-81 is necessary for DCS800 drive installations that require extensive communication or I/O:

• Integrated Control Systems: Used when the drive must communicate with a plant-wide DCS (like ABB 800xA) or a high-level PLC system (e.g., Siemens, Rockwell).

• Complex Machine Control: Employed in multi-drive systems (like rolling mills or paper machines) where drives need tight, synchronous communication over a common network.

• Remote I/O: Providing cost-effective, decentralized I/O points managed directly by the drive’s internal control program.
