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
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.

.
EtherNet/IP
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.
