1. Introduction
Ethernet communication option module connects the iS7 inverter to the
Ethernet network. It supports 2 kinds of protocol, Modbus/TCP and
Ethernet/IP.
Controlling and monitoring of inverter can be done by PLC se uence program
or any Master Module. Since Ethernet which constitutes Internet has been
used and IPv4 has been supported, wherever Internet can be done, controlling
and monitoring is possible. But, Ethernet network of the factory has to be
connected to Internet through Gateway.
With simple wiring, installation time can be reduced and maintenance
becomes easier.

7. Selecting Protocol
For using the iS7 Ethernet option module, there are 2 kinds of protocol,
Modbus TCP and Ethernet IP. You can select one of the protocols by
selecting the No.1 switch. The switch is placed next to the RJ45 connector
for Ethernet cable. No. 2, 3 and 4 of switch are not available.
Switch State Protocol
OFF (Switch at the upper position) Modbus TCP
ON (Switch at the lower position Ethernet IP
If the option module is operating, protocol will be not changed even if
switch selection is changed. Protocol is determined by the state of switch
when the option module is turned On or the inverter is initialized by ‘Yes’
execution of COM-94 Comm Update.

11. Ethernet IP
(1) Basic Constitution of Protocol
The Ethernet IP is a protocol which is implemented with the CIP
(Common Industrial Protocol), specified by the ODVA, using TCP and
UDP.
Originator: the device which is re uesting connection. Also called
client. The device can be PLC or Scanner.
Target: the device which responds to the re uest for connection. Also
called server. The device here is Inverter.

(2) Implicit Message
An Implicit Message is also called an I/O Message. This is the data
communicated between the Client (Originator) and Server (Target) with
Input Instance and Output Instance, at preset period. Class 1
