1. Introduction
Modbus/TCP communication board make SV-iP5A inverter be connected to Ethernet
network. Controlling and monitoring inverter can be done by PLC sequence 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.

(1) Opt B/D (Option card information, COM-01)
The type of communication card installed in inverter is displayed automatically.
If iP5A Modbus/TCP communication card is installed, “Modbus/TCP”message
is displayed automatically.
(2) Opt mode (drive and freq. command setting mode, COM-02)
Set the method for drive and freq. setting command of communication card.
(3) Opt Version (Option version information, COM-03)
Version of communication card installed in inverter is displayed automatically.
(4) Modbus/TCP IP, Subnet Mask, Gateway Address (COM-61~66)
IP version that Modbus/TCP option supports is v4.
All the addresses and masks are expressed as decimal number. decimal
number. decimal number. decimal number and a number between 0 and 255
is input for each decimal number.
In Modbus/TCP option, all decimal number is supposed to changed into
hexadecimal number. Also input dividing 2 higher hexadecimal numbers and
2 lower numbers
EX) For setting IP Address 196.168.10.131
Change 196.168.10.131 into hexadecimal numbers. C0.A8.0A.83
For COM-61 IP Addr Hi, input C0:A8 HEX.
ForCOM-62 IP Addr Lo, input 0A:83 HEX.
(5) Comm UpDate (COM-67)
For COM-61 ~ 66 parameters, when power inputs for the first time, the values
set in Option are expressed. But if you set, the setting is not reflected at once.
If Comm Update is set as Yes, the value is reflected to Modbus/TCP
communication card and only Modbus/TCP communication card operates again.
In the case of Parameter initialization, the values of COM-61 ~ 66 are
changed into initial values even though they aren’t reflected to actual option
board. So also in this case, Comm. UpDate has to be done.

9. Modbus/TCP Frame
(1) Modbus/TCP Frame structure
Generally, Ethernet uses Ethernet II Frame.
MODBUS Application Protocol Header (MBAP Header)
MBAP Header structure is as below.
Protocol Data Unit (PDU)
AS an actual Data of Modbus TCP, consists of Function Code and Data.
Detail information will be given at “(2) Function Code Description.”
MBAP Header( 7 bytes)
PDU (5 bytes ~)

Description
Transaction Identifier
2 Bytes
As an identified transmitting number,
is increased by 1 each time Data Frame
is send to Server from Client.
Protocol Identifier

Fixed as 0.
Length
2 Bytes
Modbus Data Frame length.
From MBAP Header to Unit Identifier,
Byte-unit length can be expressed.
Unit Identifier
1 Bytes
When Modbus TCP and Modbus RTU
are connected with Gate, Slave number
is written. When Modbus TCP is only used,
it is fixed as 0xFF.

(2) Function Code Description
Modbus TCP can be divided into Client and Server. Client gives the command
and Server responds to the command. Generally, as Client, there are PLC, HMI,
PC so on, and Server means inverter.
