5 MODBUS TCP
Modbus TCP uses the Ethernet network; so it is also necessary to configure all the parameters relating to it, as described in the chapter Ethernet
network parameters configuration.
NOTE: the AD3000 drive manages also the serial version Modbus RTU as a standard, without any optional card.
More information is available on the other product manuals.
5.1 Introduction
Modbus TCP is a communication protocol for a wide range of industrial and automation applications.
The AD3000 drive can be considered by Modbus communication as a slave (server). Data exchange is implemented through the Modicom Modbus
Reference Guide (PI-MBUS-300 Rev.J).
The communication type is master-slave (client-server) in which only the master (client) can start the transaction (by sending “queries”). The slave
(server) responds either by providing the data requested by the master (client) or by implementing the requested command.
AD3000 drive supports the MODBUS TCP protocol (on optional ETH-PROFI board).

5.2 Physical interface: ETH-PROFI optional board
To use the Modbus TCP fieldbus it is necessary to install the ETH -PROFI optional board described in paragraph Modbus TCP and the PROFIBUS
DP communication module (ETH-PROFI).
