Description

ABB CI626V1 3BSE012868R1

Key Functions

Communication Protocol Support

• Supports the PROFIBUS DP V1 protocol, operating as a Master or Slave to connect field devices (such as sensors, actuators, and frequency converters).
• Compatible with high-speed PROFIBUS DP communication (up to 12 Mbps), suitable for industrial control scenarios requiring real-time performance.

Data Interaction Capability

• Handles input/output data (e.g., process variables, status signals) and supports both periodic data transmission (cyclic communication) and aperiodic data transmission (e.g., parameter settings, diagnostic information).
• Enables seamless integration with ABB AC 800M controllers to achieve centralized monitoring and management in distributed control systems (DCS).

Diagnosis and Redundancy

• Features self-diagnosis functionality to real-time monitor communication link status and module faults (e.g., power anomalies, bus disconnections), with alarms indicated via LED indicators or system software.
• Supports redundant configuration (requires redundant power supplies and bus architecture) to enhance system reliability and reduce downtime risks.

Technical Parameters

Physical Characteristics

Appearance and Interfaces

• Module Dimensions: Approximately 36 mm (width) × 175 mm (height) × 150 mm (depth) (subject to the manual for specifics).
• Interface Types:
• PROFIBUS Interface: Connects to bus cables via a Sub-D 9-pin connector.
• Backplane Interface: Connects to the AC 800M controller rack’s backplane bus via metal contacts for power and data transmission.

LED Indicators

• PWR (Power): Green light indicates normal power supply.
• BUS (Bus Status): Flashing green light indicates active communication; off light indicates bus disconnection or fault.
• FAULT (Fault): Red light indicates module fault or communication anomaly.

Application Scenarios

• Industrial Automation Systems: Used in production line control for industries such as chemical, power, metallurgy, and pharmaceuticals to connect field devices and control systems.
• Distributed Control Systems (DCS): Serves as a core node in PROFIBUS networks to enable data interaction between controllers and remote I/O stations or intelligent devices.
• Process Control and Monitoring: Supports real-time data acquisition and command issuance, suitable for scenarios requiring high-speed communication and reliability.

Installation and Wiring

Installation Steps

1. Insert the module into the corresponding slot of the AC 800M controller rack (operate with power off).
2. Secure the module with rail clips to ensure good contact.
3. Connect the PROFIBUS bus cable: Master stations require terminal resistors (typically 120 Ω) at both ends of the bus; slave stations do not.

Wiring Considerations

• Use shielded twisted-pair cables for PROFIBUS to minimize electromagnetic interference (EMI).
• Ensure the bus positive/negative poles (red for +, black for -) match the module’s interface definitions (refer to the manual’s pin diagram).
• If configuring redundant modules, connect redundant bus cables and set corresponding hardware addresses.

Configuration and Programming

• Hardware Configuration: Define parameters such as module type, bus address (e.g., PROFIBUS slave addresses 1–126), and input/output data length via ABB Control Builder M software.
• Programming Interface: Use standard PROFIBUS communication function blocks (e.g., read input data, write output data) in PLC programs to interact with field devices.

Maintenance and Fault Handling

Daily Maintenance

• Regularly check the module’s indicator lights to ensure normal power supply and communication.
• Clean dust from the module surface to avoid poor heat dissipation (recommended every 6–12 months).
