Overview

The FENA-01 Ethernet Adapter module supports the Modbus/

TCP network protocol. This chapter contains a short description of

Modbus/TCP and the FENA-01 Ethernet Adapter module.

For information on Ethernet standards, including media and

topologies, see FENA-01 Ethernet Adapter Module Hardware

Manual (3AUA0000022986 [English]).

Modbus/TCP is a variant of the Modbus family of simple, vendor-

neutral communication protocols intended for supervision and

control of automation equipment. Specifically, it covers the use of

Modbus messaging over TCP connection on an IP network.

The implementation of the Modbus/TCP server in the FENA-01

module is done according to

• Modbus Application Protocol Specification v1.1a

• Modbus Messaging on TCP/IP Implementation Guide v1.0a

The supported Modbus commands are listed in chapter

Communication. Two simultaneous Modbus/TCP connections are

supported.

Further information on the Modbus/TCP protocol is available on

the world wide web from www.modbus.org.

The FENA-01 Ethernet Adapter module is an optional device for

ABB drives which enables the connection of the drive to an

Ethernet network. The module supports a variety of higher-level

communications protocols, including Modbus/TCP. Through the

FENA-01 Ethernet Adapter module it is possible to:
