ABB CCF 10 Modbus Coupler P 73113-4-0788 713

The ABB CCF 10 Modbus coupler, order code P 73113-4-0788 713, is a robust and compact protocol gateway designed to connect Modbus serial devices to Modbus TCP/IP networks. It is part of ABB's comprehensive range of communication interfaces for industrial automation and power systems, enabling seamless integration of legacy field devices into modern Ethernet-based control architectures.

Function and Operation

The CCF 10 acts as a bridge between a Modbus serial line (RTU or ASCII) and an Ethernet network running Modbus TCP. It converts Modbus requests from TCP clients into serial messages and forwards responses back to the clients. The coupler supports multiple simultaneous TCP connections, allowing several masters to poll serial slaves concurrently. It also features a built-in web server for easy configuration and monitoring.

Key Features

• Protocol conversion: Transparent conversion between Modbus RTU/ASCII (master or slave) and Modbus TCP.

• Dual Ethernet ports: Integrated switch for daisy-chaining, supporting redundant ring topologies (RSTP).

• Serial interface: One optically isolated RS232/RS485 port, software-selectable.

• Baud rates: Up to 115.2 kbps, with automatic baud detection option.

• Configuration: Web interface, serial console, or configuration file upload.

Technical Specifications

• Ethernet: 2 x 10/100Base-TX, auto MDI/MDIX, RJ45 connectors.

• Serial: DB9 male, supports RS232 (full modem signals) or RS485 (2-wire).

• Power supply: 24 V DC (10-36 V DC) or 100-240 V AC via external adapter (optional).

• Power consumption: < 5 W.

• Operating temperature: -40°C to +70°C, suitable for industrial cabinets.

• Mounting: DIN rail (EN 50022) or panel mount.

• Dimensions (HxWxD): 90 x 70 x 60 mm.

Applications

The CCF 10 is widely used in:

• Connecting Modbus RTU meters, protection relays, and drives to plant SCADA.

• Integrating legacy PLCs into new Ethernet control systems.

• Building remote monitoring solutions for substations and industrial sites.

• Data acquisition from distributed I/O modules over long distances using serial links.

Reliability and Diagnostics

Designed for continuous operation in harsh environments, the CCF 10 features galvanic isolation on the serial port, surge protection, and a rugged metal housing. LED indicators display power, link/activity, serial traffic, and error status. The device supports Modbus exception monitoring and can generate email alerts or SNMP traps on communication failures.

The ABB CCF 10 Modbus coupler (P 73113-4-0788 713) is a cost-effective solution to extend the life of Modbus serial equipment while transitioning to Ethernet-based automation, ensuring investment protection and system scalability.
