Modbus TCP/IP Messaging
◆
Modbus TCP/IP Overview
The Modbus TCP/IP protocol is essentially the Modbus protocol over an Modbus TCP/IP network. A master
controller (typically a PLC) sends commands to slave devices, which then perform the specified functions and
send a response to the master. The drive using the option has slave functionality.

All of the command registers, monitor registers, and parameters documented in the drive Technical Manual are
accessible via the option.
■
High Speed Access Drive Modbus TCP/IP Option Registers
Many of the registers required for control have been specially mapped to provide higher speed access to increase
network performance. Use these registers for the best response times.
As shown in
, all of the drive command registers have been mapped to this high speed access area
(Modbus TCP/IP registers 01 (Hex.) to 01F (Hex.)). In addition, the monitors shown in
are mapped for
high speed access.
