Modbus TCP Module Device Configuration
5 Device Configuration
NOTE
The Error LED flashes whenever the device is receiving power but is not
connected to a network. The Error LED will flash occasionally during the
configuration process.
5.1 Overview
The Modbus TCP Module is configured with a static IP address as default. To avoid IP
address conflicts and to ensure successful deployment, we recommend that the device is
connected directly to a PC or laptop to configure the IP address, before connecting to the
network.
5.2 Configuration Methods
• Ethernet attributes can be configured directly in the device using the on-board web
server. The default address for a new Modbus TCP Module is 192.168.0.1. The
default subnet mask is 255.255.255.0. The web server will only accept connections
from within the same subnet domain.
Changes made via the on-board web server are stored permanently in the device.
• If the subnet domain of the device is different from the controller, or if the IP address
has been changed and is no longer known, use the Ethernet Device Configuration
Tool to scan the network and identify the device. Changes made via the Ethernet
Device Configuration Tool cannot be stored permanently in the device and will be
lost when control power is cycled.
