ABB RETA-01-KIT Ethernet Adapter Module Kit

The ABB RETA-01-KIT, also cataloged as the RETA-01 Ethernet Communication Adapter, operates as a dedicated hardware component for industrial Ethernet integration within ABB variable frequency drive platforms. Installed directly into the drive control board option slot, the module converts 34-pin parallel backplane drive signals into EtherNet/IP and Modbus TCP network communications, enabling real-time speed referencing, torque control, and diagnostic telemetry streaming to supervisory PLCs.

Hardware Specifications

Backplane Bus Communication and Deterministic Networks

The adapter board attaches directly to the drive control board backplane connector, achieving high-velocity data transfer between host drive registers and internal network buffers. Deterministic networks like EtherNet/IP utilize explicit and implicit messaging over the module backplane interface to update motor speed references and drive status words within low-latency scan intervals. Firmware flash compatibility is maintained through internal flash EEPROM storage, which automatically validates drive option parameters and firmware revisions upon initialization to ensure uninterrupted parameter exchange.

Frequently Asked Questions

Q: Can the RETA-01-KIT module be inserted or removed while the host drive is powered?

A: No. Installing or removing the adapter module while auxiliary DC bus power is applied to the drive control board will damage internal logic circuitry and trigger a hardware fault on the host controller. Auxiliary power must be isolated prior to hardware manipulation.

Q: How does the module handle network protocol switching between EtherNet/IP and Modbus TCP?

A: The onboard dual-stack firmware supports both EtherNet/IP and Modbus TCP protocols concurrently. Protocol selection and profile setup execute via drive parameter group 51 settings without requiring physical DIP switch adjustments or firmware refloashing.

Field Installation Guidelines

Insert the RETA-01 module carefully into option slot 1 or option slot 2 on the drive control board, ensuring the 34-pin header seats fully into the host bus connector. Secure the board mechanically using the provided grounding screw to ensure structural stability and establish electrical frame contact.

Route shielded CAT5e or CAT6 Industrial Ethernet cable through dedicated low-voltage wiring channels, keeping a minimum clearance of 300 mm from high-power AC motor output cables and input line reactors. Terminate the RJ45 shield braid to the panel ground busbar at the cabinet entry point to suppress high-frequency PWM inverter noise and prevent ground loops. Maintain a minimum engagement of 5 full threads when torquing the PCB grounding screw to 0.8 N-m.
