Features:

  • Ethernet Bridge Connecting ABB Drives to Modbus/TCP and PROFINET IO Networks
  • Supports Up to Eight Simultaneous Modbus/TCP IP Client Connections
  • Implements Modbus/TCP Protocol per Specification 1.0 Standards
The ABB RETA-02 Adapter module serves as the communication gateway for ABB drives, enabling integration into Modbus/TCP and PROFINET IO industrial networks. It implements Modbus messaging over Ethernet using TCP/IP protocols according to the Modbus/TCP Specification 1.0, allowing the RETA-02 to function as an Ethernet bridge for drive control and supervision. The RETA-02 supports up to eight simultaneous IP connections, ensuring robust connectivity for multiple client devices. In addition to Modbus/TCP, the module supports the PROFINET IO protocol, providing flexible network compatibility for diverse automation architectures. The RETA-02 has been designed to deliver reliable protocol conversion and network interfacing within the drive system.

The RETA-02 provides essential communication functions for the drive and is a critical component of the network control path, directly affecting the proper, normal operation of the overall drive system. One RETA-02 module is required per drive for network connectivity. The RETA-02 is designed for direct installation onto compatible ABB drive units, occupying a compact form factor that integrates with the drive housing.

For applications requiring robust multi-client communication, the RETA-02 Adapter module supports up to eight simultaneous Modbus/TCP IP connections to the drive. In addition to standard single-connection operation, the multi-client configuration allows multiple supervisory systems to access the drive concurrently. The RETA-02 manages each connection independently using the internal protocol stack specified in the Modbus/TCP implementation.

The RETA-02 ABB Adapter module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
The ABB RETA-02 Ethernet Adapter Module is an optional add-on designed to integrate ABB drives into Ethernet networks, allowing the drive to function as a slave device. With this module, users can send control commands such as Start, Stop, and Run enable, as well as provide motor speed or torque references directly to the drive. It also enables interaction with the PID controller by feeding process actual values or process references.

Through the RETA-02, operators can read real-time status information, monitor actual drive values, change drive parameter settings, and reset drive faults, providing a flexible and efficient interface for industrial automation tasks. The module supports both Modbus/TCP and PROFINET protocols, making it compatible with a wide range of Ethernet-enabled automation devices.

The RETA-02 adapter module is installed into an optional slot on the drive’s motor control board. It features a robust IP20 degree of protection, a 34-pin parallel bus connector, and an RJ-45 connector for Ethernet, supporting both 10base-TX and 100base-TX media. The module supports both half and full-duplex serial communication at transfer rates of 10/100 Mbps, with a maximum segment length of 100 meters.

Designed for long-term reliability, the RETA-02 has an average current consumption of 380 mA at 5 V and an estimated minimum lifetime of 100,000 hours. Configuration is straightforward, with drive parameters set through the drive itself and an 8-way DIP switch for intranet IP address selection. This makes the RETA-02 a practical and durable solution for expanding ABB drives into networked automation systems.
