ABB FENA-21 Ethernet adapter module

ABB FENA-21 Ethernet adapter module

The F-series FENA-21 is a 2-port Ethernet adapter supporting several communication protocols: PROFINET IO, EtherNet/IP and Modbus TCP. The selection for the protocol is done via a parameter in a drive.

PROFINET

The FENA-21 Ethernet adapter supports PROFINET IO DP-V1 communication. With the FENA-01/-11 module, the PROFINET network may employ either the PROFIdrive profile or the ABB Drives profile. In addition, two transparent modes – for 16-bit and 32-bit words respectively – are available.

EtherNet/IP

The FENA Ethernet adapter acts as an EtherNet/IP server with support for ODVA AC/DC Drive, ABB drives and Transparent profiles. The adapter module supports both explicit messaging where each attribute of a class is set individually and implicit messaging using input and output instances.

Modbus TCP

The adapter module acts as a Modbus TCP server with support for ABB drives and Transparent profiles. Common read/write single and multiple register function codes are supported.
