Overview

The RETA-01 Adapter module supports the Modbus/TCP and

EtherNet/IP network protocols. This chapter contains a short

description of the above protocols and the RETA-01 Adapter

module, a delivery checklist and warranty information.

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 in an Ethernet environment using the TCP/IP

protocols.

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

module is done according to the Modbus/TCP Specification 1.0.

The supported Modbus commands are listed in chapter

Communication.

The Modbus/TCP protocol allows the RETA-01 module to be used

as an Ethernet bridge to control the drive. The RETA-01 module

supports eight simultaneous IP connections.

Further information can be obtained from www.modbus.org.

EtherNet/IP is based on the Common Industrial Protocol (CIP),

which is also the framework for both the ControlNet and

DeviceNet networks. EtherNet/IP uses standard Ethernet and

TCP/IP technology to transport CIP communication packets. The

module fulfills all requirements for certification as an Ethernet/IP

device.
