ABB's RETA-02 PROFINET IO and Modbus/TCP adapter enables fast and simple connectivity of ABB drives to a PROFINET IO or a Modbus/TCP network. With ABB fieldbus adapters, users are free to choose and integrate their power devices to virtually any automation architecture.

The RETA-02 Ethernet Adapter module is an optional device that, when mounted under the cover of ABB drives, makes it possible to: 

• Send control commands to the drive (Start, Stop, Run enable, etc.)
• Send motor speed or torque reference to the drive
• Send a process actual value or a process reference to the PID controller of the drive
• Read status information and actual values from the drive
• Change drive parameter values
• Reset a drive fault

The fieldbus adapter can be ordered installed on new drives, or the module can be retrofitted to ABB’s existing drives. Key features include the following:

• Compatible devices: Ethernet standard IEEE 802.3 and 802.3u devices
• Medium: 10base-TX or 100base-TX
• Termination: Internal
• Wiring: CAT 5 UTP, CAT 5 FTP* or CAT 5 STP* (*Recommended)
• Connector: RJ-45
• Maximum segment length: 100 m
• Topology: Bus, star
• Serial communication type: Half and full Duplex
• Transfer rate: 10/100 Mbps
• Carrier protocol: TCP/IP
• Application protocols: Modbus/TCP & PROFINET IO
