9. Modbus TCP

9.1. Overview

The OPT-3-MTPEG-IN device operates as a Modbus TCP to Modbus RTU converter and communicates to the drive using the
Modbus RTU protocol. For drives with factory fitted interface, the operating principle remains the same.

9.2. Usage Requirement

 W hen using the Modbus TCP to control the drive it is necessary to ensure that the amount of data and frequency of data exchange
does not exceed the amount of data which can be successfully exchanged on the Modbus sub-network within the permitted time.
 W hilst the Optitools Studio PC software supports communication through the Ethernet network for device commissioning, it is not
recommended to use this continuously during operation of the drive as the additional communication load may exceed the limit
resulting in loss of Cyclic communication.
o In this case, connect the PC software to the drive serial port using the USB / RS485 adaptor.
  U se port D1 or D2 of the external Ethernet adaptor.
  U se port D1 or D2 of the Compact 2 Ethernet adaptor.
  U se one of the available ports labelled "IOIOI".
o Do not connect via Ethernet if data logging is required.

9.3. Operation

9.3.1. Supported Commands
Modbus TCP supported commands and registers are the same as those for Modbus RTU. Refer to sections 4.3. Modbus RTU
Configuration Parameter on page 10 to 4.6. Modbus RTU Indirect Parameter Access on page 10 for further information.
9.3.2. IP Address
The default IP address is 192. 1 68. 1 .254, Subnet Mask 255.255.255.0
IP configuration can be changed using the internal webserver interface.
